Question

Say I have a stored proc that has a return param called Count and it is made up of the following SQL:

with temp as
(
    SELECT ROW_NUMBER() OVER( ORDER BY o.createDate) as rowNum,
           o.orderId
    FROM Orders as o

)
SELECT * FROM temp where rowNum BETWEEEN 10 and 20
SELECT @Count = COUNT(*) FROM Temp

Currently this will break because Temp is gone after the first select. Is it possible for me to set the value of the return parameter to the total number of rows in my CTE and return the rows from 10-20?

I’m thinking I might have to do this using a temp table but I’m curious if it can be done using a CTE.

Answer 1

Unfortunately, you can’t do what you are trying to do. Gordon’s answer is acceptable except that it isn’t returning a value to your variable.

You are running into a fundamental problem. CTEs only allow for one query after it.

A temp table or table variable would be the only way to go. Unless you would would go after the table again outside of the CTE to return the variable, like this:

with temp as
(
    SELECT ROW_NUMBER() OVER( ORDER BY o.createDate) as rowNum,
           o.orderId
    FROM Orders as o
)
SELECT * FROM temp where rowNum BETWEEEN 10 and 20
SELECT @Count = COUNT(*) FROM Orders
