Hi,
Perhaps try to remove the brackets ?
SELECT location FROM visiExPr where location=1 UNION SELECT location FROM
visiExPr where location=0;
(I assume you're using MySQL 4.0.x ?)
Regards,
Jocelyn Fournier

Subject: Union does not work
Hi,
Could anybody tell me why the following query does not work?
SELECT location FROM visiExPr where location=1 union (SELECT location FROM
visiExPr where location=0);
Thanks!
Dan
