Partition Elimination - response (1) by dnoeth

The date conditions are simply pushed into the stil table like any other condition resulting in partition elimination based on hard-coded values.
I don't have access to a TD13.10 right now, but for your example 1i would usually expect an access to SIMS first, followed by a (product) join to stil "enyhanced by dynamic partition elimination".
 
What are the DDL and stats for the SIMS table?
