Subject RE: Problem with MSSQL and Criteria.addSelectColumn
Date Fri, 17 Mar 2006 16:11:29 GMT
Playing around with the supplied queries with Query Analyzer
on my SQL server, I got the same problem as you with the 
non-aliased query.  However, I also got problems running the 
aliased query.

In looking for a valid query syntax, I found some references 
to the fact that in order to be compliant with the SQL-92 
standard, MS SQL Server 2000 is more strict on implied joins.
E.g.

  WHERE CSProfileAuthorization.CSAUTHORIZATIONREGISTRYID=
  CSAuthorizationRegistry.ID 

I suspect that this is the reason that MS SQL doesn't work
and MySQL does.  IMHO, you'd have the same issue if you went
to Oracle or any DB that applies the standards more strictly.
I know I've hit problems like that in moving MySQL development 
code to MS SQL (especially foreign key contraint enforcement).

You might try restructuring the query to use two explicit 
joins to create a more DB vendor independent format.
