Microsoft Jet 4.0 provides enhanced support for ANSI 92 keywords. For example, with Microsoft Jet 4.0 you can use the ANSI CREATE PROCEDURE syntax to create a new query. As a result of this support there are a number of new reserved words. If you have table or column names that conflict with one of the reserved words, you will now get a syntax error when referencing it in a query.
