Hi @huosenyuan ,
Thanks for debugging.
Is there any data in `t_job0` and `t_job1`? Looks like we need to figure out why we get null from `statement.getResultSet()`.

Hi @huosenyuan ,
> List<QueryResult> queryResults = executeQuery0(); has result; after The result set in statement has been cleared；
Thanks for feedback.
Who did clear this `List<QueryResult>`? I just wanna figure out this SS's bug or not.
> Can not support hsqldb
I suppose so, but I am a little confused that why this exception came there.

`t_job0` and `t_job1` has data;
`List<QueryResult> queryResults = executeQuery0(); ` has result; after The result set in statement has been cleared；
so
`statement.getResultSet() ` statement does not query results
