DXParametricQueryDD

Purpose:

This is the class that is used to represent a parametric query for DD.

Methods:

initialization
   init(LPDISPATCH ds, LPCTSTR queryString);

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

datastore
   LPDISPATCH datastore();

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

qlType
   short qlType();

Gets query language type.

queryString
   BSTR queryString();

Gets query string.

prepare
   prepare([VARIANT parms]);

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

execute
   execute([VARIANT parms]);

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

status
   long status();

Gets the status of the query.

result
   VARIANT result();

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

resultSetCursor
   LPDISPATCH resultSetCursor();

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

numberOfResults
   long numberOfResults();

Gets the number of results.
