How do I include a text (or ntext) field in a query that uses an aggregate function

eg

SELECT textField, someOtherField, COUNT(anotherFieldAgain) AS Total
FROM tblTable
GROUP BY textField, someOtherField

In MS access I could use the FIRST or LAST function to do this (on a SQL Server back-end) - and not include it in the group by clause.  How do I do this in SQL Server?

The best you can really do is to do a cast/convert on it:


SELECT convert(varchar(8000),textField), someOtherField, COUNT(anotherFieldAgain) AS Total
FROM tblTable
GROUP BY convert(varchar(8000),textField), someOtherField


Of course, you loose anything over 8000 bytes.....Why do you need to group on a text field???

It's not so much that I want to group on the field.  What I'm doing is counting how many records there are in related tables and outputting all the data in this table.  Maybe I could count the related records in a subquery?

Yes, you could count in a subquery--those are about the only options...
