Mike, thanks for going through the wiki page. Especially, the store section since I am not too familiar with store code. Following are my responses 1)Mike:Obtain collation id(type) from DataValueDescriptor(DVD) through DVD.getCollateId method. The way I had collation in mind, collation type would be stored only in DataTypeDescriptor(DTD) and DVD would only store Collator object in DVD, ie the DVD will be unaware of how the Collator object was created using a specific collation type. The DVD for non-default-collation subclass of SQLChar is CollatorSQLChar and currently, it's constructor looks as follows public CollatorSQLChar(String val, RuleBasedCollator collatorForCharacterDatatypes) ie, no collation type info is passed to the CollatorSQLChar. May be to support the store requirement, we should add another parameter to the constructor above, called collationId. This collationId can later be retrieved by store using DVF.getCollateId. Any comments from anyone?
Yes looks like you need to pass collateId in constructor and save it around just for this call, I don't think it should be used for anything
else. I don't see another way unless it is possible to write a function that returns a collate id based on an input RuleBasedCollator.
