                 Key: DERBY-2528
                 URL: https://issues.apache.org/jira/browse/DERBY-2528
             Project: Derby
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 10.3.0.0
            Reporter: Mamta A. Satoor
         Assigned To: Mamta A. Satoor


As per the wiki page http://wiki.apache.org/db-derby/BuiltInLanguageBasedOrderingDERBY-1478,
Section Collation Determination, item 2)
)<column definition> (of character string type) SQL spec Section 11.1 <schema definition>,
General Rule 3 specifies that the character set associated with schema is used as the default
character set for all <column definitions>. Based on this, character columns in user
tables will have USER character set associated with them and hence collation type of UCS_BASIC/TERRITORY_BASED.
The collation derivation will be implicit. 

In order for column definition to pick up the collation from the schema, correct collation
type should be available in schema. In Derby implementation world, this translates having
correct collation type in SchemaDescriptor. This jira entry is to track the work required
in associating collation type to a SchemaDescriptor.
