Without looking too hard, would using a TOP 1 in the sub select work? -----Original Message----- From: Bruce Sorge [mailto:[EMAIL PROTECTED] Sent: 01 February 2007 17:26 To: CF-Talk Subject: SQL QUestion
I have a lot of duplicate information in a table. I know how to query to find the dupes, but I am having problems with deleting them (there are thousands). I tried this: DELETE FROM CODES WHERE Code = (SELECT Code, COUNT(Code) AS NumOccurrences FROM Codes GROUP BY Code HAVING ( COUNT(Code) > 1 )) Now of of course even if this one did work, it just occured to me that it will not do what I want it to. What I want is to leave one instance of the code in the database and delete the duplicates only. Is this possible without me going line by line?
