select count(*) from table;count ------- 100 (1 row) is correct select count(*) from table where col::text ~~* '%text%'; count ------- 1 (1 row) is correct.

That is out of 100 records there is one that has "text" in column "col" so the !~~* should return 99 rows. ?? -wes
select count(*) from table where col is null; (null is neither equal nor not-equal to anything, even null) Cheers, Steve -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
