Future Keywords
Microsoft has also reserved a number of keywords for future use. These are not implemented in MS SQL Server 2000 and hence do not represent valid SQL commands. Nevertheless, it will be a good idea to avoid these altogether in your code (as identifiers, for instance) as they might render your code invalid in future versions. You may notice that some of the keywords listed here are, in fact, mandated by the SQL99 standard.Microsoft SQL Server reserved future keywords:
