>  The SQL in dummy.iq:
> {code:java}
> !use scott
> !set outputformat mysql
> select sum(mgr) from emp;
> !ok{code}
> Because the data type of MGR is TINYINT, according to SUM's data type inference rules, the data type of SUM is also TINYINT.
> This SQL throws the exception:
> {code:java}
> java.sql.SQLException: Error while executing SQL "select sum(mgr) from emp": Value 38835 out of range {code}
