> val tableA = tableEnv.sqlQuery("select custom_func(a) as a, custom_func(b) as b from tableS")
> tableEnv.registerTable("tableA", tableA)
> val tableB = tableEnv.sqlQuery("select ROW(a, b) as body from tableA")
> tableEnv.registerTable("tableB", tableB)
> val tableC = tableEnv.sqlQuery("select body.a, body.b from tableB")
> In this logic, the custom_func is executed four times
> tableC === select Row(custom_func(a) as a, custom_func(b) as b).a, Row(custom_func(a) as a, custom_func(b) as b).b from tableS
