      Description

      The LIKE transformations and optimizations are disabled when using a database with a territory-based collation. See the following email thread: http://www.nabble.com/territory-based-collations-and-optimizations-for-the-LIKE-operator-td19111725.html#a19111725 That thread, in turn, refers to DERBY-1478. It would be nice if we did not have to perform full table scans for LIKE queries in databases with territory-based collations.
