Purpose:
This is the class that is used to represent a parametric query for VisualInfo for AS/400.
Methods:
init(LPDISPATCH ds, LPCTSTR queryString);
This method must be called following the creation of a DXParametricQueryV4 object (except for methods returning a DXParametricQueryV4 object). The method initializes the query object with the datastore and query string. The input parameter LPDISPATCH pointer contains a DXDatastoreV4 object.
LPDISPATCH datastore();
Gets the datastore. The returned LPDISPATCH pointer contains a DXDatastoreV4 object.
short qlType();
BSTR queryString();
prepare([VARIANT parms]);
Prepares the query. The optional parameter is in the form af an array of DXNVPairV4 objects.
execute([VARIANT parms]);
Executes the query. The optional parameter is in the form af an array of DXNVPairV4 objects.
long status();
VARIANT result();
Gets the result collection. The value of the VARIANT is a DXResultsV4 object.
LPDISPATCH resultSetCursor();
Gets the result set cursor. The returned LPDISPATCH pointer contains a DXResultSetCursorV4 object.
long numberOfResults();
Gets the number of results.
