查询的count的数目如何接收？

pRst->Open("select count(*) from information",_variant_t((IDispatch*)pConn),adOpenStatic,adLockOptimistic,adCmdText);

pRst->Open("select count(*) as cnt from information",_variant_t((IDispatch*)pConn),adOpenStatic,adLockOptimistic,adCmdText);
int x = pRst->GetCollect("cnt").intVal;
