## Interface NamedParameterJdbcOperations

- All Known Implementing Classes:
    NamedParameterJdbcTemplate

      public interface NamedParameterJdbcOperations

  Interface specifying a basic set of JDBC operations allowing the use of named parameters rather than the traditional '?' placeholders.

  This is an alternative to the classic `JdbcOperations` interface, implemented by `NamedParameterJdbcTemplate`. This interface is not often used directly, but provides a useful option to enhance testability, as it can easily be mocked or stubbed.

  Since:
    2.0
  Author:
    Thomas Risberg, Juergen Hoeller

- - ### Method Detail

    - #### getJdbcOperations

          JdbcOperations getJdbcOperations()

                    throws DataAccessException

      Execute a JDBC data access operation, implemented as callback action working on a JDBC PreparedStatement. This allows for implementing arbitrary data access operations on a single Statement, within Spring's managed JDBC environment: that is, participating in Spring-managed transactions and converting JDBC SQLExceptions into Spring's DataAccessException hierarchy.

      The callback action can return a result object, for example a domain object or a collection of domain objects.

      Parameters:
        `sql` - SQL to execute
        `paramSource` - container of arguments to bind to the query
        `action` - callback object that specifies the action
      Returns:
        a result object returned by the action, or `null`
      Throws:

    - #### queryForList

          <T> List<T> queryForList(String sql,

      Query given SQL to create a prepared statement from SQL and a list of arguments to bind to the query, expecting a result list.

      The results will be mapped to a List (one entry for each row) of result objects, each of them matching the specified element type.

      Parameters:
        `sql` - SQL query to execute
        `paramMap` - map of parameters to bind to the query (leaving it to the PreparedStatement to guess the corresponding SQL type)

      Returns:
        a List that contains a Map per row

    - #### queryForRowSet

      Query given SQL to create a prepared statement from SQL and a list of arguments to bind to the query, expecting a SqlRowSet.

      The results will be mapped to an SqlRowSet which holds the data in a disconnected fashion. This wrapper will translate any SQLExceptions thrown.

      Note that that, for the default implementation, JDBC RowSet support needs to be available at runtime: by default, Sun's `com.sun.rowset.CachedRowSetImpl` class is used, which is part of JDK 1.5+ and also available separately as part of Sun's JDBC RowSet Implementations download (rowset.jar).

      Parameters:
        `sql` - SQL query to execute
        `paramSource` - container of arguments to bind to the query
      Returns:
        a SqlRowSet representation (possibly a wrapper around a `javax.sql.rowset.CachedRowSet`)
      Throws:
        `DataAccessException` - if there is any problem executing the query
