Hi, I was looking for something like this. InMssql when I use a query like selece a,b from some table where a.x=b.y,then if a is having say 30000 records and b is having 4 records then it will compare all the 30000 records with the 4 records one by one,but if I make it where b.y=a.x then it will be faster. I know with index I could increase the performance by 50 %,but what other possibilities are there to improve the performance Stephan Szabo wrote: > On Mon, 28 Oct 2002, Savita wrote: > > > Using explain I am not able to get the detailed information. > > What information are you looking to get? > > ---------------------------(end of broadcast)--------------------------- > TIP 3: if posting/reading through Usenet, please send an appropriate > subscribe-nomail command to majordomo@postgresql.org so that your > message can get through to the mailing list cleanly -- Best Regards - Savita ---------------------------------------------------- Hewlett Packard (India) +91 80 2051288 (Phone) 847 1288 (HP Telnet) ----------------------------------------------------
