Kathey Marsden updated DERBY-3854:
----------------------------------
Component/s: SQL
> Implement LIKE transformations and optimizations for databases using
> territory-based collations
> -----------------------------------------------------------------------------------------------
>
> Key: DERBY-3854
> URL: https://issues.apache.org/jira/browse/DERBY-3854
> Project: Derby
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 10.3.3.0, 10.4.1.3, 10.5.0.0
> Reporter: Rick Hillegas
>
> 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.
