MySQL joins and COUNT(*) from another table

Question

I have two tables: groups and group_members.

The groups table contains all the information for each group, such as its ID, tit

Answer 1

Your groups_main table has a key column named id. I believe you can only use the USING syntax for the join if the groups_fans table has a key column with the same name, which it probably does not. So instead, try this:

LEFT JOIN groups_fans AS m ON m.group_id = g.id

Or replace group_id with whatever the appropriate column name is in the groups_fans table.
