Multiple Select Statements using SQL Server 2005 “WITH” Statement

Question

I am trying to use the \"WITH\" statement in SQL Server 2005. It seems to work fine if I do something like:

WITH MyBigProducts AS (SELECT * FROM Products WHE         


        

Answer 1

I believe that Common Table Expressions are only valid for immediate use which is why you are getting an error for the "SELECT Count(*) FROM MyBigProducts". In order to reuse a CTE you should use a temporary table instead

DECALRE @BigProducts TABLE (...[declaration omitted]...)

INSERT INTO @BigProducts
SELECT * 
FROM Products 
WHERE Size='Big'


SELECT Name FROM @BigProducts
SELECT Count(*) FROM @BigProducts

Please correct me if I am wrong.
