> Key: CALCITE-1051

> Project: Calcite
> Issue Type: Bug

>
> Underflow exception occurs when executing query with more then 19 values in
> the in-clause.
> Example below illustrates the problem in the csv example:
> {code}
> select e.name from emps as e where e.empno in (130, 130, 130, 130, 130, 130,
> 130, 130, 130, 130, 130, 130, 130, 130, 130, 130, 130, 130, 130, 130 );
> Error: Error while executing SQL "select e.name from emps as e where e.empno
> in (130, 130, 130, 130, 130, 130, 130, 130, 130, 130, 130, 130, 130, 130,
> 130, 130, 130, 130, 130, 130 )": Underflow (state=,code=0)
> {code}
> The SqlToRelConverter will convert this to a SemiJoin. Literals in the IN
> clause value list are scaled. When the type of the literal does not have a
> scale set, as happens with a java.lang.Integer, the default value of the
> type.scale is chosen, which is Integer.MIN_VALUE. Scaling to this value
> causes the underflow.
