void SetParamNull( int nIndex, BOOL bNull = TRUE );
Parameters
nIndex
The zero-based index of the parameter.
bNull
If TRUE (the default value), the parameter is flagged as Null. Otherwise, the parameter is flagged as non-Null.
Remarks
Call this member function to flag a parameter as Null (specifically having no value) or as non-Null. Unlike SetFieldNull, you can call SetParamNull before you have opened the recordset.
SetParamNull is typically used with predefined queries (stored procedures).
