Mamta A. Satoor updated DERBY-2416:
-----------------------------------
Attachment: DERBY2416_CollationSensitiverShells_stat_v2.txt
DERBY2416_CollationSensitiverShells_diff_v2.txt
With patch DERBY2416_CollationSensitiverShells_diff_v2.txt, I am extending the
patch attached yesterday
(DERBY2416_CollationSensitiveVarcharShell_diff_v1.txt). This latest patch has
collation sensitive subclasses for SQLVarchar, SQLLongvarchar and SLQClob. The
collation sensitive subclass for SQLChar is already checked in as
CollatorSQLChar.
So, In brief, the change description for yesterday's patch applies to the patch
I am attaching right now. In addition, it applies the same logic for creating
subclasses for SQLVarchar, SQLLongvarchar and SLQClob.
These classes are not hooked into Derby runtime yet and hence won't impact the
existing tests.
I will go ahead and commit this patch, so I can make more progress on language
based ordering task. If anyone has any comments on this patch, please let me
know about them and I can address them in subsequent patches.
> Provide a shell for a subclass of SQLChar and SQLVarch which will use the

> The existing SQLChar datatype has the Derby's default collation which is
> UCS_BASIC defined on them. With Derby 10.3, we want to support an additional
> collation for char datatypes which will be based on the territory. This jira
> issue is the placeholder for creating subclass of SQLChar which will use the
> passed Collator to do the collation. The current use of this class in Derby
> 10.3 will be for territory based collation but this class can be used in
> future for other kinds of collations like case-insensitive etc.
