Union query help

01-13-2004, 04:17 PM
After reading several threads about union queries I came up with this:

"SELECT Sum(views) AS SumViews1 FROM Vehicles Where O_AirBag = 'true' UNION SELECT Sum(views) AS SumViews2 FROM Vehicles Where O_DualAirBag = 'true'"

but it errors out. If I run it without the union, and run each sql statement seperately they run fine. Why isn't the union working? Any ideas?

you have to name the fields the same name. Change SumViews2 to be SumViews1

Nope, still saying i have an error in my sql syntax. Maybe something is up with my database?

I checked my php version and it is above 4 so it is supposed to accept union queries.

it should have nothing to do with your php version, it should be dependent on your MySQL version.

I'll have to check and see what version it is, but I'm pretty sure it's a recent version.
