Makes sense. I take it that this is a deviation from the ANSI 92 standard, then? What happens if I put an ORDER BY in a view, then call an ORDER BY in a query, e.g.: CREATE VIEW test_view AS SELECT client_name, city, zip FROM clients WHERE zip IS NOT NULL ORDER BY zip; SELECT * FROM test_view ORDER BY city; Does the second ORDER BY override or suppliment the view ORDER BY, or is it ignored? -Josh ______AGLIO DATABASE SOLUTIONS___________________________ Josh Berkus Complete informationtechnology josh@agliodbs.com and data management solutions (415) 565-7293 for law firms, small businesses fax 621-2533 and non-profit organizations.
