CRecordset::m_hstmt
Contains a handle to the ODBC statement data structure, of type HSTMT, associated with the recordset.
Remarks
Each query to an ODBC data source is associated with an HSTMT.
警告
Do not use m_hstmt before Open has been called.
Normally you do not need to access the HSTMT directly, but you might need it for direct execution of SQL statements. The ExecuteSQL member function of class CDatabase provides an example of using m_hstmt.
