Hi guys,

As title says im getting that error message, I know why im getting it but what is the best work around? Ive tried a few but must be getting the syntax wrong.

SELECT     PartNumber, Manufacture, COUNT(PartNumber) as TheCount
FROM         CounterfeitParts
WHERE      COUNT(PartNumber) > 1
Group BY PartNumber, Manufacture

Thanks,
Dean

Incorrect syntax near the keyword 'Group'.

the correct syntax would be this:
SELECT     PartNumber, Manufacture, COUNT(PartNumber) as TheCount
FROM         CounterfeitParts
Group BY PartNumber, Manufacture
HAVING COUNT(PartNumber) > 1

however, doing a count(PartNumber) here is usually better COUNT(*) instead ...

I know Guy (aka Scary Scar Puffy Shirt Dude) has already correctly answered your question, but if it helps I have an article out there on SQL Server Group By Solutions, and point #3 illustrates the HAVING clause.   If the article helps you, please click the 'Yes' button at the bottom.
