---------------------------------
Assignee: (was: Kristine Hahn)
> Document implicit casting rules
> -------------------------------
>
> Key: DRILL-2443
> URL: https://issues.apache.org/jira/browse/DRILL-2443
> Project: Apache Drill
> Issue Type: Improvement
> Components: Documentation
> Reporter: Victoria Markman
>
> This document should describe the implicit casting rules in different
> operations: joins, "union all" and functions.
> For example,
> if t1.a1 is defined as an INTEGER and t2.a2 is defined as BIGINT, using these
> two columns in a join predicate will result in t1.a1 to be converted to
> BIGINT implicitly and explicit cast will not be needed:
> select * from t1, t2 where t1.a1 = t2.a2;
