I am running a dual athlon 1800 with an gig of ram. I am running postgres 7.2. I have a table that hs 15 million rows. I have a query that has one columns and the select cluase and one column in the where clause with no joining or sub-queries. If I do not index the column from the where clause the query returns the 150,000 rows in 4 and a half minutes. If in do index the column from the where clause using a btree the 150,000 rows return in 11 and a half minutes.
Any insight would be greatly appreciated. Donny L. Drummonds ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
