Hi Michael, Yes, I understand this but, I would like to have the results of both "table1.name, table2.name" sorted as one column. Is this possible?

If you want to order by table1.name and table2.name, just enter them in a comma-separated-list after ORDER BY, e.g., SELECT table1.name, table2.name, <other selected columns> FROM table1, table2 WHERE table1.id = table2.id ORDER BY table1.name, table2.name Check out the following link for the online docs: <http://www.postgresql.org/docs/current/static/queries-order.html> It doesn't explicitly give you an example of sorting on more than one column, but the syntax explanation at the top includes it. Does this help? Michael Glaesemann grzm myrealbox com
