Chris Westin updated DRILL-2001:
--------------------------------
Summary: Poor error message when arithmetic expression with MIN/MAX
functions on a string type (was: Exception is thrown in arithmetic expression
with MIN/MAX functions on a string type)
> Poor error message when arithmetic expression with MIN/MAX functions on a
> string type
> -------------------------------------------------------------------------------------
>
> Key: DRILL-2001
> URL: https://issues.apache.org/jira/browse/DRILL-2001
> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Data Types
> Affects Versions: 0.8.0
> Reporter: Victoria Markman
> Priority: Minor
> Fix For: Future
>
>
> We do support MIN/MAX(<string data type>).
> However, if I inadvertently were to use this in arithmetic expression, I
> would get an exception:
> {code}
> { "a1": "aaa" }
> { "a1": "bbb" }
> { "a1": "bbb" }
> { "a1": "eee" }
> {code}
> Works correctly:
> {code}
