Is it possible to have temp tables in a function?

Question

Apparently, I can\'t use them. I\'m getting an error message like:

Invalid use of a side-effecting operator \'SELECT\' within a function

Answer 1

You can also do it with a CTE. See the template browser in SSMS. IntelliSense confuses the issue and will show an error until you complete the CTE and the following insert/select, but it will work.

Answer 2

No, per this thread where the same question was asked, you cannot, but you can use a table variable

DECLARE @MyTempTableVariable TABLE (SCHEMA)

INSERT INTO @MyTempTableVariable
SELECT bleh
FROM bleh
