## Proposed changes
Add cases regarding whether MTMV normal rewriting is still supported
when constants exist in various query statements. There are various types of statements:
("plac_x" is a placeholder and will be replaced with various pre-prepared constants in the code.)
1. select plac_1 from tb
2. select col1 from (select plac_1 as col1 from tb) as t1
3. select plac_1 from tb group by plac_1
4. select plac_1 from tb where plac_1 >= 1 group by plac_1
5. select col1 from (select plac_1 as col1 from tb where plac_1 >= 1) as t1
6. select plac_1 from tb left join (select plac_1 as col1 from tb) as t1 on plac_1 = t1.col1
7. select plac_1 from tb1 left join (select plac_1 as col1 from tb2) as t1 on plac_1 = t1.col1 group by plac_1
8. select t1.col1 from (select plac_1 as col1 from tb1 where plac_1 = plac_1) as t1 left join (select plac_1 as col2 from tb2) as t2 on t1.col1 = t2.col2 group by t1.col1
9. select t1.col1 from (select plac_1 as col1 from tb1 where plac_1 = plac_1 group by col1) as t1 left join (select plac_1 as col2 from tb2) as t2 on t1.col1 = t2.col2 group by t1.col1
10. select plac_1 from tb1 left join (select plac_2 as col1 from tb2) as t1 on plac_1 = t1.col1
11. select plac_1 from tb1 left join (select plac_2 as col1 from tb2) as t1 on plac_1 = t1.col1 group by plac_1
12. select t1.col1 from (select plac_2 as col1 from tb1 where plac_2 = plac_2) as t1 left join (select plac_1 as col2 from tb2) as t2 on t1.col1 = t2.col2 group by t1.col1
13. select t1.col1 from (select plac_2 as col1 from tb2 where plac_2 = plac_2 group by col1) as t1 left join (select plac_1 as col2 from tb1) as t2 on t1.col1 = t2.col2 group by t1.col1
