The query is run against a staging db and the table only contains some 500

But I will check the query as you have suggested to see what is going on.

Hi All,
I've run into a odd problem, where calling the count function hangs my

you're using left outer join to locate rows in A for which there is
missing a row in B. the more idiomatic SQL for this is:
UPDATE a SET a.y=1 WHERE NOT EXISTS (SELECT * FROM b WHERE a.x = b.x)
works on any DB and performs better too.
