All Implemented Interfaces:
  CallableStatement, PreparedStatement, Statement, Wrapper

    public class JDBCCallableStatement

extends JDBCPreparedStatement
implements CallableStatement

The interface used to execute SQL stored procedures. The JDBC API provides a stored procedure SQL escape syntax that allows stored procedures to be called in a standard way for all RDBMSs. This escape syntax has one form that includes a result parameter and one that does not. If used, the result parameter must be registered as an OUT parameter. The other parameters can be used for input, output or both. Parameters are referred to sequentially, by number, with the first parameter being 1.

(JDBC4 clarification:)

       {?= call <procedure-name>[(<arg1>,<arg2>, ...)]}
       {call <procedure-name>[(<arg1>,<arg2>, ...)]}

IN parameter values are set using the `set` methods inherited from `PreparedStatement`. The type of all OUT parameters must be registered prior to executing the stored procedure; their values are retrieved after execution via the `get` methods provided here.

A `CallableStatement` can return one `ResultSet` object or multiple `ResultSet` objects. Multiple `ResultSet` objects are handled using operations inherited from `Statement`.

For maximum portability, a call's `ResultSet` objects and update counts should be processed prior to getting the values of output parameters.

### HSQLDB-Specific Information:

As with many DBMS, HSQLDB support for stored procedures is not provided in a completely standard fashion.

Beyond the XOpen/ODBC extended scalar functions, stored procedures are typically supported in ways that vary greatly from one DBMS implementation to the next. So, it is almost guaranteed that the code for a stored procedure written under a specific DBMS product will not work without at least some modification in the context of another vendor's product or even across a single vendor's product lines. Moving stored procedures from one DBMS product line to another almost invariably involves complex porting issues and often may not be possible at all. Be warned.

One kind of HSQLDB stored procedures and functions is Java routines that map directly onto the static methods of compiled Java classes found on the class path of the engine at runtime. The CREATE PROCEDURE or CREATE FUNCTION statements are used in SQL to support the Java methods.

The other kind of HSQLDB stored procedures is SQL routines that are created as part of schemas. Overloaded methods are supported and resolved according to the type of parameters. With procedures, `OUT` and `IN OUT` parameters are also supported.

In addition, HSQLDB stored procedure call mechanism allows the more general HSQLDB SQL expression evaluation mechanism. This extension provides the ability to evaluate simple SQL expressions, possibly containing Java method invocations.

With HSQLDB, executing a `CALL` statement that produces an opaque (OTHER) or known scalar object reference has virtually the same effect as:

     CREATE TABLE DUAL (dummy VARCHAR);
     INSERT INTO DUAL VALUES(NULL);
     SELECT <simple-expression> FROM DUAL;

HSQLDB functions can return a single result set. Procedures that return one or more result sets. Here is a very simple example of an HSQLDB stored procedure generating a user-defined result set:

     package mypackage;

     import java.sql.ResultSet;
     import java.sql.SQLException;

     class MyLibraryClass {

          public static ResultSet mySp() throws SQLException {
              return ctx.getConnection().createStatement().executeQuery("select * from my_table");
          }
     }

Constructor Detail

### JDBCCallableStatement

    public JDBCCallableStatement(JDBCConnection c,
                                 String sql,
                                 int resultSetType,
                                 int resultSetConcurrency,
                                 int resultSetHoldability)
                          throws org.hsqldb.HsqlException,
                                 SQLException

  Constructs a new JDBCCallableStatement with the specified connection and result type.

  Parameters:
    `c` - the connection on which this statement will execute
    `sql` - the SQL statement this object represents
    `resultSetType` - the type of result this statement will produce
  Throws:
    `org.hsqldb.HsqlException` - if the statement is not accepted by the database
    `SQLException` - if preprocessing by driver fails

Method Detail

### registerOutParameter

    public void registerOutParameter(int parameterIndex,
                                     int sqlType)
                              throws SQLException

  Registers the OUT parameter in ordinal position `parameterIndex` to the JDBC type `sqlType`. All OUT parameters must be registered before a stored procedure is executed.

  The JDBC type specified by `sqlType` for an OUT parameter determines the Java type that must be used in the `get` method to read the value of that parameter.

  If the JDBC type expected to be returned to this output parameter is specific to this particular database, `sqlType` should be `java.sql.Types.OTHER`. The method `getObject(int)` retrieves the value.

  ### HSQLDB-Specific Information:

  HSQLDB supports this feature. This method can be called after a PrepareCall method. HSQLDB has already determined which parameters are OUT or INOUT parameters, therefore this method only checks and throws an exception if the parameter is not of the correct form. The data type argument is ignored

  The `get` method to read the value of the parameter is determined by the engine based on the data type of the parameter. Furthermore, HSQLDB supports multiple OUT and INOUT parameters for stored procedures.

  Specified by:
    `registerOutParameter` in interface `CallableStatement`
  Parameters:
    `parameterIndex` - the first parameter is 1, the second is 2, and so on
    `sqlType` - the JDBC type code defined by `java.sql.Types`. If the parameter is of JDBC type `NUMERIC` or `DECIMAL`, the version of `registerOutParameter` that accepts a scale value should be used.
  Throws:
    `SQLException` - JDBC 4.1 [if the parameterIndex is not valid;] if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if `sqlType` is a `ARRAY`, `BLOB`, `CLOB`, `DATALINK`, `JAVA_OBJECT`, `NCHAR`, `NCLOB`, `NVARCHAR`, `LONGNVARCHAR`, `REF`, `ROWID`, `SQLXML` or `STRUCT` data type and the JDBC driver does not support this data type
  See Also:
    `Types`

### registerOutParameter

    public void registerOutParameter(int parameterIndex,
                                     int sqlType,
                                     int scale)
                              throws SQLException

  Registers the parameter in ordinal position `parameterIndex` to be of JDBC type `sqlType`. (JDBC4 clarification:) All OUT parameters must be registered before a stored procedure is executed.

  The JDBC type specified by `sqlType` for an OUT parameter determines the Java type that must be used in the `get` method to read the value of that parameter.

  This version of `registerOutParameter` should be used when the parameter is of JDBC type `NUMERIC` or `DECIMAL`.

  ### HSQLDB-Specific Information:

  HSQLDB supports this feature.

  Specified by:
    `registerOutParameter` in interface `CallableStatement`
  Parameters:
    `parameterIndex` - the first parameter is 1, the second is 2, and so on
    `sqlType` - the SQL type code defined by `java.sql.Types`.
    `scale` - the desired number of digits to the right of the decimal point. It must be greater than or equal to zero.
  Throws:
    `SQLException` - JDBC 4.1[if the parameterIndex is not valid;] if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if `sqlType` is a `ARRAY`, `BLOB`, `CLOB`, `DATALINK`, `JAVA_OBJECT`, `NCHAR`, `NCLOB`, `NVARCHAR`, `LONGNVARCHAR`, `REF`, `ROWID`, `SQLXML` or `STRUCT` data type and the JDBC driver does not support this data type
  See Also:
    `Types`

### wasNull

    public boolean wasNull()
                    throws SQLException

  Retrieves whether the last OUT parameter read had the value of SQL `NULL`. Note that this method should be called only after calling a getter method; otherwise, there is no value to use in determining whether it is `null` or not.

  ### HSQLDB-Specific Information:

  HSQLDB supports this feature.

  Specified by:
    `wasNull` in interface `CallableStatement`
  Returns:
    `true` if the last parameter read was SQL `NULL`; `false` otherwise
  Throws:
    `SQLException` - if a database access error occurs or this method is called on a closed `CallableStatement`

### getString

    public String getString(int parameterIndex)
                     throws SQLException

  Retrieves the value of the designated JDBC `CHAR`, `VARCHAR`, or `LONGVARCHAR` parameter as a `String` in the Java programming language.

  For the fixed-length type JDBC `CHAR`, the `String` object returned has exactly the same value the (JDBC4 clarification:) SQL `CHAR` value had in the database, including any padding added by the database.

  ### HSQLDB-Specific Information:

  HSQLDB supports this feature.

  Specified by:
    `getString` in interface `CallableStatement`
  Parameters:
    `parameterIndex` - the first parameter is 1, the second is 2, and so on
  Returns:
    the parameter value. If the value is SQL `NULL`, the result is `null`.
  Throws:
    `SQLException` - JDBC 4.1[if the parameterIndex is not valid;] if a database access error occurs or this method is called on a closed `CallableStatement`
  See Also:
    `setString(java.lang.String, java.lang.String)`

                       throws SQLException

  (JDBC4 modified:) Retrieves the value of the designated JDBC `BIT` or `BOOLEAN` parameter as a `boolean` in the Java programming language.

  ### HSQLDB-Specific Information:

  HSQLDB supports this feature.

  Specified by:
    `getBoolean` in interface `CallableStatement`
  Parameters:

                              throws SQLException

  Registers the designated output parameter. This version of the method `registerOutParameter` should be used for a user-defined or `REF` output parameter. Examples of user-defined types include: `STRUCT`, `DISTINCT`, `JAVA_OBJECT`, and named array types.

  All OUT parameters must be registered before a stored procedure is executed.

  For a user-defined parameter, the fully-qualified SQL type name of the parameter should also be given, while a `REF` parameter requires that the fully-qualified type name of the referenced type be given. A JDBC driver that does not need the type code and type name information may ignore it. To be portable, however, applications should always provide these values for user-defined and `REF` parameters. Although it is intended for user-defined and `REF` parameters, this method may be used to register a parameter of any JDBC type. If the parameter does not have a user-defined or `REF` type, the typeName parameter is ignored.

  Note: When reading the value of an out parameter, you must use the getter method whose Java type corresponds to the parameter's registered SQL type.

  ### HSQLDB-Specific Information:

  HSQLDB supports this feature.

  Specified by:
    `registerOutParameter` in interface `CallableStatement`
  Parameters:
    `parameterIndex` - the first parameter is 1, the second is 2,...
    `sqlType` - a value from `Types`
    `typeName` - the fully-qualified name of an SQL structured type
  Throws:

  Registers the OUT parameter named `parameterName` to the JDBC type `sqlType`. All OUT parameters must be registered before a stored procedure is executed.

  The JDBC type specified by `sqlType` for an OUT parameter determines the Java type that must be used in the `get` method to read the value of that parameter.

  If the JDBC type expected to be returned to this output parameter is specific to this particular database, `sqlType` should be `java.sql.Types.OTHER`. The method `getObject(int)` retrieves the value.

  ### HSQLDB-Specific Information:

  HSQLDB supports this feature.

  Specified by:
    `registerOutParameter` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `sqlType` - the JDBC type code defined by `java.sql.Types`. If the parameter is of JDBC type `NUMERIC` or `DECIMAL`, the version of `registerOutParameter` that accepts a scale value should be used.
  Throws:
    `SQLException` - JDBC 41.[if parameterName does not correspond to a named parameter;] if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if `sqlType` is a `ARRAY`, `BLOB`, `CLOB`, `DATALINK`, `JAVA_OBJECT`, `NCHAR`, `NCLOB`, `NVARCHAR`, `LONGNVARCHAR`, `REF`, `ROWID`, `SQLXML` or `STRUCT` data type and the JDBC driver does not support this data type or if the JDBC driver does not support this method

  (JDBC4 clarification:)

  All OUT parameters must be registered before a stored procedure is executed.

  For a user-named parameter the fully-qualified SQL type name of the parameter should also be given, while a REF parameter requires that the fully-qualified type name of the referenced type be given. A JDBC driver that does not need the type code and type name information may ignore it. To be portable, however, applications should always provide these values for user-named and REF parameters. Although it is intended for user-named and REF parameters, this method may be used to register a parameter of any JDBC type. If the parameter does not have a user-named or REF type, the typeName parameter is ignored.

  Note: When reading the value of an out parameter, you must use the `getXXX` method whose Java type XXX corresponds to the parameter's registered SQL type.

                   throws SQLException

  Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the `java.lang` equivalent objects should be used.

  The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface `SQLData`), the JDBC driver should call the method `SQLData.writeSQL` to write it to the SQL data stream. If, on the other hand, the object is of a class implementing `Ref`, `Blob`, `Clob`, `NClob`, `Struct`, `java.net.URL`, or `Array`, the driver should pass it to the database as a value of the corresponding SQL type.

  Note that this method may be used to pass datatabase- specific abstract data types.

  ### HSQLDB-Specific Information:

  HSQLDB supports this feature.

  Specified by:
    `setObject` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `x` - the object containing the input parameter value
    `targetSqlType` - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
    `scale` - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For all other types, this value will be ignored.
  Throws:
    `SQLException` - JDBC 4.1[if parameterName does not correspond to a named parameter;] if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if `targetSqlType` is a `ARRAY`, `BLOB`, `CLOB`, `DATALINK`, `JAVA_OBJECT`, `NCHAR`, `NCLOB`, `NVARCHAR`, `LONGNVARCHAR`, `REF`, `ROWID`, `SQLXML` or `STRUCT` data type and the JDBC driver does not support this data type

                   throws SQLException

  Sets the value of the designated parameter with the given object. This method is like the method `setObject` above, except that it assumes a scale of zero.

  ### HSQLDB-Specific Information:

  HSQLDB supports this feature.

  Specified by:
    `setObject` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `x` - the object containing the input parameter value
    `targetSqlType` - the SQL type (as defined in java.sql.Types) to be sent to the database
  Throws:
    `SQLException` - JDBC 4.1[if parameterName does not correspond to a named parameter;] if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if `targetSqlType` is a `ARRAY`, `BLOB`, `CLOB`, `DATALINK`, `JAVA_OBJECT`, `NCHAR`, `NCLOB`, `NVARCHAR`, `LONGNVARCHAR`, `REF`, `ROWID`, `SQLXML` or `STRUCT` data type and the JDBC driver does not support this data type

### setObject

    public void setObject(String parameterName,
                          Object x)
                   throws SQLException

  Sets the value of the designated parameter with the given object. The second parameter must be of type `Object`; therefore, the `java.lang` equivalent objects should be used for built-in types.

  The JDBC specification specifies a standard mapping from Java `Object` types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database.

  Note that this method may be used to pass datatabase- specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface `SQLData`, the JDBC driver should call the method `SQLData.writeSQL` to write it to the SQL data stream. If, on the other hand, the object is of a class implementing `Ref`, `Blob`, `Clob`, `NClob`, `Struct`, `java.net.URL`, or `Array`, the driver should pass it to the database as a value of the corresponding SQL type.

  This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

                 throws SQLException

  Sets the designated parameter to SQL `NULL`. This version of the method `setNull` should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

  Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.

### setCharacterStream

    public void setCharacterStream(String parameterName,
                                   Reader reader,
                                   long length)
                            throws SQLException

  Sets the designated parameter to the given `Reader` object, which is the given number of characters long. When a very large UNICODE value is input to a `LONGVARCHAR` parameter, it may be more practical to send it via a `java.io.Reader` object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from UNICODE to the database char format.

  Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

  Specified by:
    `setCharacterStream` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `reader` - the `java.io.Reader` object that contains the UNICODE data used as the designated parameter
    `length` - the number of characters in the stream
  Throws:
    `SQLException` - JDBC 4.1[if parameterName does not correspond to a named parameter;] if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method

                        throws SQLException

  Sets the designated parameter to the given input stream. When a very large ASCII value is input to a `LONGVARCHAR` parameter, it may be more practical to send it via a `java.io.InputStream`. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII to the database char format.

  Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

  Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of `setAsciiStream` which takes a length parameter.

  Specified by:
    `setAsciiStream` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `x` - the Java input stream that contains the ASCII parameter value
  Throws:
    `SQLException` - if parameterName does not correspond to a named parameter; if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method
  Since:
    JDK 1.6, HSQLDB 2.0

### setBinaryStream

                         throws SQLException

  Sets the designated parameter to the given input stream. When a very large binary value is input to a `LONGVARBINARY` parameter, it may be more practical to send it via a `java.io.InputStream` object. The data will be read from the stream as needed until end-of-file is reached.

  Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

  Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of `setBinaryStream` which takes a length parameter.

  Specified by:
    `setBinaryStream` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `x` - the java input stream which contains the binary parameter value
  Throws:
    `SQLException` - if parameterName does not correspond to a named parameter; if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method

  Specified by:
    `setCharacterStream` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `reader` - the `java.io.Reader` object that contains the Unicode data
  Throws:
    `SQLException` - if parameterName does not correspond to a named parameter; if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method JDK 1.6, HSQLDB 2.0

### setNCharacterStream

    public void setNCharacterStream(String parameterName,
                                    Reader value)
                             throws SQLException

  Sets the designated parameter to a `Reader` object. The `Reader` reads the data till end-of-file is reached. The driver does the necessary conversion from Java character format to the national character set in the database.

  Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

  Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of `setNCharacterStream` which takes a length parameter.

  Specified by:
    `setNCharacterStream` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `value` - the parameter value
  Throws:

    `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method JDK 1.6, HSQLDB 2.0

### setClob

    public void setClob(String parameterName,
                        Reader reader)
                 throws SQLException

  Sets the designated parameter to a `Reader` object. This method differs from the `setCharacterStream (int, Reader)` method because it informs the driver that the parameter value should be sent to the server as a `CLOB`. When the `setCharacterStream` method is used, the driver may have to do extra work to determine whether the parameter data should be send to the server as a `LONGVARCHAR` or a `CLOB`

  Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of `setClob` which takes a length parameter.

  Specified by:
    `setClob` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `reader` - An object that contains the data to set the parameter value to.
  Throws:
    `SQLException` - if parameterName does not correspond to a named parameter; if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method JDK 1.6, HSQLDB 2.0

### setBlob

    public void setBlob(String parameterName,
                        InputStream inputStream)
                 throws SQLException

  Sets the designated parameter to a `InputStream` object. This method differs from the `setBinaryStream (int, InputStream)` method because it informs the driver that the parameter value should be sent to the server as a `BLOB`. When the `setBinaryStream` method is used, the driver may have to do extra work to determine whether the parameter data should be send to the server as a `LONGVARBINARY` or a `BLOB`

  Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of `setBlob` which takes a length parameter.

  Specified by:
    `setBlob` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `inputStream` - An object that contains the data to set the parameter value to.
  Throws:
    `SQLException` - if parameterName does not correspond to a named parameter; if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method JDK 1.6, HSQLDB 2.0

### setNClob

    public void setNClob(String parameterName,
                         Reader reader)
                  throws SQLException

  Sets the designated parameter to a `Reader` object. This method differs from the `setCharacterStream (int, Reader)` method because it informs the driver that the parameter value should be sent to the server as a `NCLOB`. When the `setCharacterStream` method is used, the driver may have to do extra work to determine whether the parameter data should be send to the server as a `LONGNVARCHAR` or a `NCLOB`

  Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of `setNClob` which takes a length parameter.

  Specified by:
    `setNClob` in interface `CallableStatement`
  Parameters:
    `parameterName` - the name of the parameter
    `reader` - An object that contains the data to set the parameter value to.
  Throws:
    `SQLException` - if parameterName does not correspond to a named parameter; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; if a database access error occurs or this method is called on a closed `CallableStatement`
    `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method JDK 1.6, HSQLDB 2.0

### getObject

    public <T> T getObject(int parameterIndex,
                           Class<T> type)
                throws SQLException

  Returns an object representing the value of OUT parameter `parameterIndex` and will convert from the SQL type of the parameter to the requested Java data type, if the conversion is supported. If the conversion is not supported or null is specified for the type, a `SQLException` is thrown.

  At a minimum, an implementation must support the conversions defined in Appendix B, Table B-3 and conversion of appropriate user defined SQL types to a Java type which implements `SQLData`, or `Struct`. Additional conversions may be supported and are vendor defined.

  Parameters:
    `parameterIndex` - the first parameter is 1, the second is 2, and so on
    `type` - Class representing the Java data type to convert the designated parameter to.
  Returns:
    an instance of `type` holding the OUT parameter value
  Throws:
    `SQLException` - if conversion is not supported, type is null or another error occurs. The getCause() method of the exception may provide a more detailed exception, for example, if a conversion error occurs
    `SQLFeatureNotSupportedException` - if the JDBC driver does not support this method

### close

    public void close()
               throws SQLException

  Does the specialized work required to free this object's resources and that of it's parent classes.

  Specified by:
    `close` in interface `Statement`
  Overrides:
    `close` in class `JDBCPreparedStatement`
  Throws:
    `SQLException` - if a database access error occurs

### closeOnCompletion

    public void closeOnCompletion()
                           throws SQLException

  Specifies that this `Statement` will be closed when all its dependent result sets are closed. If execution of the `Statement` does not produce any result sets, this method has no effect.

  Note: Multiple calls to `closeOnCompletion` do not toggle the effect on this `Statement`. However, a call to `closeOnCompletion` does effect both the subsequent execution of statements, and statements that currently have open, dependent, result sets.

  Throws:
    `SQLException` - if this method is called on a closed `Statement`

### isCloseOnCompletion

    public boolean isCloseOnCompletion()
                                throws SQLException

  Returns a value indicating whether this `Statement` will be closed when all its dependent result sets are closed.

  Returns:
    `true` if the `Statement` will be closed when all of its dependent result sets are closed; `false` otherwise
  Throws:
    `SQLException` - if this method is called on a closed `Statement`

### executeQuery

    public ResultSet executeQuery()
                           throws SQLException

  Executes the SQL query in this `PreparedStatement` object and returns the `ResultSet` object generated by the query.

  ### HSQLDB-Specific Information:

  HSQLDB supports this method for a call to a FUNCTION that returns a result. For a PROCEDURE that returns one or more results, the first result is returned.

  If the FUNCTION or PROCEDURE does not return a ResultSet, an `SQLException` if thrown.

  Specified by:
    `executeQuery` in interface `PreparedStatement`
  Overrides:
    `executeQuery` in class `JDBCPreparedStatement`
  Returns:
    a `ResultSet` object that contains the data produced by the query; never `null`
  Throws:
    `SQLException` - if a database access error occurs, this method is called on a closed `PreparedStatement` or the SQL statement does not return a `ResultSet` object
