The Upgrade Advisor detected a script that contains a colon (:) following a reserved keyword. In earlier versions of SQL Server, this syntax is ignored and the statements execute successfully. In SQL Server 2005 and later, this syntax causes the statement to fail when the database compatibility mode is set to 90 or later.
When you upgrade to SQL Server 2008, user databases maintain their compatibility mode. Using a colon after a reserved keyword is ignored when the database compatibility mode is set to 80 or earlier.
