Fix cte rewrite by mv wrongly when query has scalar aggregate but view no
For example as following, it should not be rewritten by materialized view successfully
// materialzied view define
def mv20_1 = """
select
l_shipmode,
l_shipinstruct,
sum(l_extendedprice),
count()
from lineitem
left join
orders on lineitem.L_ORDERKEY = orders.O_ORDERKEY
group by
l_shipmode,
l_shipinstruct;
"""
// query sql
def query20_1 =
"""
select
sum(l_extendedprice),
count()
from lineitem
left join
orders
on lineitem.L_ORDERKEY = orders.O_ORDERKEY
"""
Fix predicates compensation by mistake
For example as following, it can return right result, but it's wrong earlier.
// materialzied view define
def mv7_1 = """
select l_shipdate, o_orderdate, l_partkey, l_suppkey
from lineitem
left join orders
on lineitem.l_orderkey = orders.o_orderkey
where l_shipdate = '2023-12-08' and o_orderdate = '2023-12-08';
"""
// query sql
def query7_1 = """
select l_shipdate, o_orderdate, l_partkey, l_suppkey
from (select * from lineitem where l_shipdate = '2023-10-17' ) t1
left join orders
on t1.l_orderkey = orders.o_orderkey;

and optimize some code usage and add more comment for method
