When using union the order by clause needs to us a number denoting the column number instead of a column name try: select brand from tableofitemsoftype1 union select brand from tableofitemsoftype2 group by 1. ----- Original Message ----- From: Brenton Bills <fud@mail.theinternet.com.au> To: <zope@zope.org> Sent: Monday, January 17, 2000 3:47 PM Subject: [Zope] re: SQL Unions. Hi people, I have been attempting to do an SQL union from an ZSQL Method with MysqlDA as my back end database. The only problem is I cant seen to get it to work. Are unions a bad thing? Should I be using something else. Eg. Get all the brands we have in our database. select brand from tableofitemsoftype1 union select brand from tableofitemsoftype2 group by brand.

From what I understand this would get all of the brands and group them together and place them in a single column results table?
