SQL query update

Any assistance is appreciated. We need to update ibf_posts.author_id. I have tried this but it doesn't seem to work. No errors but the query hasn't finished after hours of running. 2.9g dbase. ibf_posts is 1.9g

UPDATE ibf_posts SET author_id = (SELECT member_id FROM ibf_members 
                 WHERE ibf_members.members_display_name = ibf_posts.author_name)

Tables: ibf_posts, ibf_members

ibf_posts.author_name = ibf_members.members_display_name

ibf_posts.author_id = ibf_members.member_id

[slinky = slinky]
[4814 = 4814]

but we have:

[slinky = slinky]
[0 = 4814]
Solution

  • Try it like this:

    UPDATE ibf_posts, ibf_members
SET ibf_posts.author_id = ibf_members.member_id
WHERE ibf_members.members_display_name = ibf_posts.author_name;
