> ----------------------------
>
> Key: DRILL-6369
> URL: https://issues.apache.org/jira/browse/DRILL-6369
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.13.0

>
> The {{typeof()}} function reports the type of a column. For example:
> {noformat}
> SELECT typeof(a) FROM (VALUES (1)) AS T(a);
> +---------+
> | EXPR$0 |
> +---------+
> | BIGINT |
> +---------+
> {noformat}
> But, it does not work on constants:
> {noformat}
> SELECT typeof(10) FROM (VALUES (1)) AS T(a);
> Error: SYSTEM ERROR: IllegalArgumentException:
> Can not set org.apache.drill.exec.vector.complex.reader.FieldReader field
> org.apache.drill.exec.expr.fn.impl.UnionFunctions$GetType.input to
> org.apache.drill.exec.expr.holders.IntHolder
> {noformat}
