I'm not sure about Sybase (in fact, I'm curious, does it work??), but MS SQL
Server 2000 also allows the notation where []'s surround database objects:

SELECT [Date] FROM [Table]

This is not dependent on QUOTED_IDENTIFIER.

In fact, it would appear that this is preferred syntax for MSSQL.  As far as
I can tell, auto-generated SQL by SQL Server tools always use []'s (for
example, click on a table in Enterprise Manager, [Copy], and then [Paste]
into notepad or some such, and you'll see the autogenerated CREATE TABLE
statement with all objects inside []'s).  Of course this may be totally
unportable, and a way for MS keep the lobsters in the pot.
