I have four tables that I join to get one record set about a customer. They are: UserInfo, ExtraAddr, DslInfo, and DslExtra.
Specifically the main tables are joined with: SELECT * FROM UserInfo u, DslInfo d WHERE u.UserID = d.UserID; I've been adding more data to other tables and LEFT JOINING to get the data (since it's optional). SELECT * FROM UserInfo u, DslInfo d LEFT JOIN DslExtra e ON d.DslID = e.DslID LEFT JOIN ExtraAddr a ON a.UserID = u.UserID WHERE u.UserID = d.UserID; However it appears this syntax is not valid in MySQL 5.x (It works on 4.x). I need to LEFT JOIN *two* tables, but I can't seem to get it. I just LEFT JOIN the DslExtra table in the above example it works just fine, it's only when I try and do the second that I get an error. Unknown column 'u.UserID' in 'on clause' Can I not do this type of multi table left join with 5.x? Or do I need to recraft the query? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
