------------------------------------
Summary: agg can't be pushed down correctly
Key: CALCITE-5566
URL: https://issues.apache.org/jira/browse/CALCITE-5566
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.33.0
Reporter: shampoo liu
{code:sql}
select count(*) from (select max("position_title") "position_title" from
"foodmart"."employee" where "gender" like '%a%' group by "birth_date",
"gender") where "position_title" like '%z%'
{code}
The plan generated from sql above is as this :
{code:java}
PLAN=EnumerableAggregate(group=[{}], EXPR$0=[COUNT()])
JdbcToEnumerableConverter
JdbcFilter(condition=[LIKE($2, '%z%')])
JdbcAggregate(group=[{8, 15}], position_title=[MAX($5)])
JdbcFilter(condition=[LIKE($15, '%a%')])
JdbcTableScan(table=[[foodmart, employee]])
{code}
Expected:
{code:java}
PLAN=JdbcToEnumerableConverter
JdbcAggregate(group=[{}], EXPR$0=[COUNT()])
JdbcFilter(condition=[LIKE($2, '%z%')])
JdbcAggregate(group=[{8, 15}], position_title=[MAX($5)])
JdbcFilter(condition=[LIKE($15, '%a%')])
JdbcTableScan(table=[[foodmart, employee]])
{code}
