The text, ntext, or image data type cannot be selected as DISTINCT

I have you use the DISTINCT in my sql select statement.
here is what I did:

Set RS=Condata.Execute("SELECT DISTINCT course,title,Name,CRhr,inst_type,COU_DESC,long_des c FROM schedule WHERE subj='" & tsubj & "' ORDER BY course,title")

I got the error: Microsoft OLE DB Provider for SQL Server </SPAN> (0x80040E14)
The text, ntext, or image data type cannot be selected as DISTINCT.

There is a field, Cou_Desc, uses Ntext datatype. If I change this field to Varchar then asp app works fine. The problem that if I change this field datatype, then something else will not work .

The question is: Is there a way to make the sql statement works without changing the field datatype?

Thanks very much for your help

Just cast it to a varchar.

Example:

Code:

SELECT DISTINCT course,
	title,
	Name,
	CRhr,
	inst_type,
	CAST(COU_DESC As varchar(1000)) As COU_DESC,
	long_desc
FROM schedule 
WHERE subj = '" & tsubj & "' 
ORDER BY course,
	title
