Apologies as this probably isn't really for this list but...

In postgresql you can execute a statement such as: 

SELECT 1 > 2;

And it would return 'f'

Does anyone know if you can do this in SQL Server as I have to do a
conversion of some prewritten SQL code.

MTIA,

Graham.

If you look here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/tsqlref/ts_oa-oz_3qpf.asp

"Unlike other SQL Server data types, a Boolean data type cannot be specified 
as the data type of a table column or variable, and cannot be returned in a 
result set."

Generally you'd use a BIT type instead of a boolean, but that's not going to 
help you here. I'm not even sure if you can use a boolean expression in the 
column-list part of a select.

The only thing I can think of is to use a case:
  SELECT WHEN 1>2 THEN 1 ELSE 0 END;

As to why MSSQL doesn't support booleans, you could try asking their tech 
support, but I wouldn't get your hopes up.

No, I don't know. Can't you simply try?
