Fix Error “The function ‘DENSE_RANK’ must have an OVER clause with ORDER BY” in SQL Server

Posted on by Ian

If you’re getting an error that reads “The function ‘DENSE_RANK’ must have an OVER clause with ORDER BY” in SQL Server, it’s probably because you’re calling the DENSE_RANK() function without an ORDER BY clause.

Window functions such as DENSE_RANK() require an OVER clause, and that clause must have an ORDER BY clause. If you’re getting the above error, it’s likely that you’re providing an OVER clause, but you’re omitting the ORDER BY clause.

To fix this error, add an ORDER BY clause to the OVER clause.
