Subject [jira] Updated: (DERBY-2377) Document language based ordering which will be implemented by code related sub-tasks of DERBY-1478.
Date Thu, 24 May 2007 22:30:16 GMT

Mike Matrigali updated DERBY-2377:

I still having a hard time seeing the value of the table of valid expressions, and worry that
the list is wrong - I have not had a chance to think about how collation may affect every
statement.  I wonder if there is anything we can tie this to.  Somewhere we must explain where
it is valid to use CHAR (because it can be compared) but can not use CLOB.  

again I am not sure of the right wording, but create index statement does not really include
a comparison operator.   Internally the ordering of the index is very dependent on the collation
of the datatypes but I don't think that is ever a user documented.   

going from our reference guide many of the things listed as statements are actually clauses.
 So at least from the chapter of contents the following clauses could be affected:
# SQL clauses

    * CONSTRAINT clause
    * GROUP BY clause
    * HAVING clause
    * ORDER BY clause
    * WHERE clause

> Document language based ordering which will be implemented by code related sub-tasks
of DERBY-1478.
