Have a look at "Delimited Identifiers" in Books Online.  "SET 
QUOTED_IDENTIFIER ON" affects how the double-quote symbol works.  Off, it 
works like a single-quote, as a string delimiter.  On, it indicates an object 
identifier (e.g. table name or column name).  

Rules of the game are that ODBC connections default to ON, and db-lib to OFF. 
 tsql's behavior is, er, undefined in this regard, as would be a ct-lib 
connection (e.g. sqsh).  ON adheres to SQL-92; OFF reflects how db-lib has 
consistently worked since Sybase delivered its first server 20 years ago.

If I were writing your query, it would look like this:

        select Description, [Manufacturer Code], [Item Category Code]
        from [TEST SML$Item] where ([No_] = 'A4800A')

That's not standard SQL (yours is), but it will work with Microsoft servers 
irrespective of the QUOTED_IDENTIFIER setting.
