How do I generate random number for each row in a TSQL Select?

Question

I need a different random number for each row in my table. The following seemingly obvious code uses the same random value for each row.

SELECT table_name,

If you don't need it to be an integer, but any random unique identifier, you can use newid()

SELECT table_name, newid() magic_number 
FROM information_schema.tables
