问题 On our production SQL2000 instance, we have a database with hundreds of stored procedures, many of which use a technique of creating a #TEMP table "early" on in the code and then various inner stored procedures get EXECUTEd by this parent sProc.

In testing with SQL2008, I find 2 manifestations of

问题 When I run the following query in SQL Server 2014 to create a temporary table: CREATE TABLE #temp ( location char(16) null, location_desc varchar(25) null, Emp_Num EMPNUM null ) I receive the error: Cannot find the data type empnum. empnum is a user-defined data type.
