arprilia Posted August 29, 2007 Share Posted August 29, 2007 Greetings to all.... I've encountered some problems with my query.... Although it's executed successfully, it takes a lot of time... the query:- SELECT pm_ic, pm_nama FROM a LEFT JOIN b ON (a.pm_id,a.iklan_id) = (b.pm_id,b.iklan_id) WHERE b.statusmohon_id = '98' AND b.iklandetail_id = '15' ORDER BY a.pm_nama BUT, when i remove the ORDER BY statement, it executes faster... Before this i used this query:- SELECT pm_ic,pm_nama FROM a,b WHERE a.pm_id=b.pm_id AND a.iklan_id=b.iklan_id AND b.statusmohon_id='98' AND b.iklandetail_id='15' ORDER BY pm_nama Any suggestions? Thanx in advance.... Quote Link to comment Share on other sites More sharing options...
