Question

I have an oracle query to delete rows in a child table, but the query doesn’t work because of too many values in the in clause. Is there a different way I can write this by using join or something to make it work?

delete from PROCESS 
where PACKAGE_ID in (select id from PACKAGE where NAME like 'Test%');

---

Had used * instead of id in the inner select there, so when I switched to id it worked. But I’m still curious if this can be written in a different way, as there is a limit of 1000(?) items in an in clause.

Answer 1

The limit of 1000 items in an IN clause only applies when you “manually” specify them. It doesn’t apply when the items are returned by a sub-query.

I think the way you have it now is the way to go.
