CDBVariant::Clear
Call this member function to clear the CDBVariant object.
void Clear( );
Remarks
If the value of the m_dwType data member is DBVT_DATE, DBVT_STRING, or DBVT_BINARY, Clear frees the memory associated with the union pointer member. Clear sets m_dwType to DBVT_NULL.
The CDBVariant destructor calls Clear.
