关于CRecordSet::GetRecordCount()

Question

无法直接得到： long count=0;
if(  !IsEOF() ) //safely checking 
{
count=m_RecordSet.GetRecordCount(); //record current position
m_RecordSet.MoveLast();
SetAbsolutePosition(count); //restore position
SQLRowCount(m_RecordSet.m_hstmt,&count);//get record count
// m_RecordSet.MoveFirst();
}
else if( m_RecordSet.IsOpen() )
{
SQLRowCount(m_RecordSet.m_hstmt,&count);//get record count
} return count;
