- Query returns rows when using optimization goal "allrows_oltp". The showplan was indicating the use of MERGE JOIN and Serial Mode.
- Query doesn't return rows when using optimization goal "allrows_mix". The showplan was indicating the use of MERGE JOIN and Parallelism.
- Query return rows when using optimization goal "allrows_mix" after running update index statistics. The showplan was indicating the use of NESTED LOOP JOIN and Parallelism.
Problem solved by executing update statistics.
