How can I aquire pessimistic locking using MFC ODCB classes ?
 
I used this code but no exception is raising on the second process.
 
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////

CString sSQL = "SELECT * FROM table_1 WHERE table_id = 1 FOR UPDATE";

// open recordset:

try

{

    if(!m_pSet->IsOpen())

    {

        m_db.BeginTrans();

        m_pSet->Open(CRecordset::snapshot, sSQL); // dynasets not supported

    }

}

catch(CDBException *e)

{

    e->ReportError();

    e->Delete();

    m_db.Rollback();

}

//////////////////////////////////////////////////////////

 

Thanx.
