select /*+ SET_VAR(query_timeout = 600) */ subq_0.`c1` as c0 from (select ref_1.`s_name` as c0, ref_1.`s_suppkey` as c1, ref_1.`s_address` as c2, ref_1.`s_address` as c3 from regression_test_query_p0_sql_functions_window_functions.tpch_tiny_supplier as ref_1 where (ref_1.`s_name` is NULL) or (ref_1.`s_acctbal` is not NULL)) as subq_0 where (subq_0.`c3` is NULL) or (subq_0.`c2` is not NULL)
reason:
FunctionIsNull and FunctionIsNotNull execute returns a const column, but their VectorizedFnCall::is_constant returns false, which causes problems with const handling when VCompoundPred::execute.
This pr converts const column to full column in VCompoundPred execute. In the future, there will be a more thorough solution to such problems.
