I'd like to do this, which is perfectly acceptable in SSMS:
SELECT A, B, NULL AS 'C', Shape FROM database.dbo.PARCELS WHERE PID_NUM IN ( 'someCriteria')
When I pass this query to MakeQueryLayer_Management it will create the object but no records are returned. If i drop " NULL AS 'C' " the Query Layer will be populated with rows. I am 100% confident my query returns records.
What is the proper syntax in ESRI's implementation of SQL to populate an aliased field with NULL?
