> Sample models are attached.  User query is:
> SELECT * FROM v_TV_SHOWS.v_SHOWS_ACTORS2
> WHERE SHOW_NAME LIKE '%E%' AND 
> NOT ACTOR_SHOW_ID IN (SELECT ACTOR_SHOW_ID FROM v_TV_SHOWS.v_SHOWS_ACTORS2  WHERE ACTOR_NAME = 'MALCOLM JAMAL-WARNER')
> OPTION DEBUG and MMProcess.log are attached.
> Customer complaint is that the query contains criteria on ACTOR_NAME and ACTOR_SHOW_ID which is coming from Oracle and on SHOW_NAME which is coming from SQL Server.  In the query plan, there is a SELECT node that does not have criteria to Oracle.  Instead it is SELECT * which pulls all records.  Customer tables are huge so this is an issue for them.
