      Description

      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.
