You are using the table alias "dj" in the subquery (the query enclosed in parentheses), but then you try to access the same table alias outside of that subquery - that appears to be the problem. But without seeing the entire query, not sure.

As JRCPrez suggests and based on your own statement, you cannot do this.  It's a scope issue.  The column only exists within the scope of the subquery.  You cannot reference it outside that scope.

You need to include whatever table is aliased as t3 in the FROM clause.

In your where clause, you have a line that says "and r.login = t3.login" but, in your join (the from clause), you only reference tables with the aliases of r, u, cu, and dj. You need to include the table with the alias of t3.
