Hi,

Le Samedi 14 Juin 2003 17:01, Emmanuel Engelhart a écrit :

Taken from the postgresql manual 
(http://www.postgresql.org/docs/view.php?version=7.3&idoc=0&file=sql-select.html#SQL-UNION):
ORDER BY and LIMIT can be attached to a sub-expression if it is enclosed in 
parentheses. Without parentheses, these clauses will be taken to apply to the 
result of the UNION, not to its right-hand input expression.


Regards.
