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

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
