How to combine to boolean collumns ?

Hi, my name is Wilhelm and I'm new to this forum.

I having problems with a SQL SELECT statement. I'm trying to combine two boolean columns in ms sql server 2000.

I tried this:

SELECT (Bol1 OR Bol2) as Bol

Anyone have any suggestion why this don't work ?
I think i have done something similar in Orcale ones.SELECT (Bol1 | Bol2) as Bol|||I just found out. Thanks anyway :)
