Booleans?

Hello.
I just changed the databases of a website from Access to SQL Server.
Converting the bases went smothly, but now I recieve error message to my SQL-quereries:
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid column name 'True'.

The query is: "Select pieces,date from orders where active = True AND company_id <> 19 AND authorize_wait = 0 ORDER BY send_date desc"

When I change int the query to: "active = 1" the page works like before (with Access)

I supose SQL Server is able to understand commands with True/False-quereries, so what is wrong here?
Thank you for your help
/CalleMSSQL does not define a "True" or "False" variable. You need to either use a one as you have in your example OR define a local variable

declare @.True bit
set @.True = 1
Select pieces,date
from orders
where active = @.True
AND company_id <> 19
AND authorize_wait = 0
ORDER BY send_date desc|||Thank you for your response!
