Hello, I am little bit unsure when index is used for sorting and when not. I have two almost same SQL first uses sort using index and second not. The only difference is in DESC keyword.
the SQL is as follows: select * from bills where closedtime < '2012-06-08 12:04:36.343 ' AND CLOSED = TRUE order by closedtime limit 1 select * from bills where closedtime < '2012-06-08 12:04:36.343 ' AND CLOSED = TRUE order by closedtime DESC limit 1 of course i can supply explain analyze if needed. Second query on same data is about 10 - 100 times slower(does not use index for sorting) Where is mistake or am I missing something?
