pengzhiwei updated CALCITE-2551:
--------------------------------
Description:
In the sql as follow:
{code:java}
select empno from emp
where not case when true then deptno in (10,20) else true end
{code}
A ClassCastException was thrown out as follow:
{code:java}
java.lang.ClassCastException: org.apache.calcite.sql.fun.SqlCase cannot be cast
to org.apache.calcite.sql.SqlBasicCall
at
org.apache.calcite.sql2rel.SqlToRelConverter.pushDownNotForIn(SqlToRelConverter.java:987)
at
org.apache.calcite.sql2rel.SqlToRelConverter.convertWhere(SqlToRelConverter.java:1070)
at
{code}
The problem is that the SqlToRelConverter#pushDownNotForIn method miss
consideration
for SqlCase.
