> Reporter: Julian Hyde
> Assignee: Julian Hyde
>
> Cannot implement a JOIN whose ON clause contains a mixture of equi and theta
> conditions. The equivalent query expressed using WHERE can be implemented.
> The solution is to make EnumerableJoinRule split the condition into equi and
> non-equi parts, provided that the join type is inner.
