Re: Optimizing IN queries

Isak,

Looks to me like most of the time is spent doing "not in (select a ton
of rows from bilkaib)".

Try something like "not exists (select null from bilkaib b where
b.dokumnr = dok.dokumnr and alusdok = 'LY')".

Thank you very much.
Query seems to return now immediately.

dok.dokumnr is not null
bilkaib.dokumnr can be null

I hope that modified query produces same results as original.

Andrus.
