I'll be the first to admit this is a bit off-topic, and I'd happily listen to any suggestions of where else I should take this question (as long as it doesn't hurt :) )

My perl code has generated the following query, and all looks good to me:

select csGroups.ID as groupid,csUsers.UserName as username,csUsers.ID as id,csGroups_lang.Title as grouptitle from csGroups_lang,csUsers,csGroups,csUsers_Groups where csGroups.ID = csGroups_lang.ID and csUsers.ID = csUsers_Groups.UserID and csGroups.ID = csUsers_Groups.GroupID and (id IN (1,2)) order by username asc limit 0,10

But the MySQL database i've connected to via dbi doesn't like it. It's reason:

Unknown column 'csUsers_Groups.UserID' in 'where clause'

I have verified that csUsers_Groups.UserID does indeed exist. Do any of you Perl/DB gurus know if you have to select a column from a table in order to be allowed to use the column in your where clause?
