Purpose:

This is the class that is used to represent a parametric query for ImagePlus for OS/390.

Methods:

initialization
   init(LPDISPATCH ds, LPCTSTR queryString);

This method must be called following the creation of a DXParametricQueryIP object (except for methods returning a DXParametricQueryIP object). The method initializes the query object with the datastore and query string. The input parameter LPDISPATCH pointer contains a DXDatastoreIP object.

datastore
   LPDISPATCH datastore();

Gets the datastore. The returned LPDISPATCH pointer contains a DXDatastoreIP object.

qlType
   short qlType();

Gets query language type.

queryString
   BSTR queryString();

Gets the query string.

prepare
   prepare([VARIANT parms]);

Prepares the query. The optional parameter is in the form af an array of DXNVPairIP objects.

execute
   execute([VARIANT parms]);

Executes the query. The optional parameter is in the form af an array of DXNVPairIP objects.

status
   long status();

Gets the status of the query.

result
   VARIANT result();

Gets the result collection. The value of the VARIANT is DXResultsIP object.

resultSetCursor
   LPDISPATCH resultSetCursor();

Gets the result set cursor. The returned LPDISPATCH pointer contains a DXResultSetCursorIP object.

numberOfResults
   long numberOfResults();

Gets the number of results.
