Depesz,
do you always have this: "(cr='00' or db='00')"? or do the values (00) change? if they don't change, or *most* of the queries have "(cr='00' or db='00')", than the biggest time difference you will get after creating this index: create index test on bilkaib (kuupaev) where cr='00' or db='00';
I have always cr='00' or db='00' clause. Separate values are never tested. I changed by queries back to old values and created this single index. This seems to be even better that Vladimir suggestion. Thank you very much.
