That's because using EXEC to run the dynamic SQL creates its own session, so an ordinary temporary table would be out of scope to any subsequent code. For a system variable summary table, see Section 5.1.5, Server System Variable Reference.For more information about manipulation of system variables, see Section 5.1.9, Using System Variables. For example, if a user_name or host_name value in an account name is legal as an unquoted identifier, you need not quote it. SELECT * FROM global_temp.view1.
