I think that the SQL standard should be extended to include:
blah blah blah ORDER::COLLATION BY blah blah blah
-OR-
blah blah blah ORDER(COLLATION) BY blah blah blah
It would require the engine to have the collation in its system tables. Other collaltions
could be inserted, written. For example, 'US-EN-NA'=>US English, Numeric Alpha ordering. So
any database could order any language based on tables. The local user would not even have to
have the font to display it, if they weren't interested in displaying it.
I will probably write to the SQL standards board someday soon to propose this.
