ANSI-89 wildcard characters
Use this set of wildcard characters when you use the Find and Replace dialog
box to find and optionally replace data in an Access database or an Access
project. You also use these characters when you run select and update queries
against an Access database, but you do not use them in queries run against an
Access project. For more information about using select and update queries,
see the articles Create a simple select query and Update the data in a
database.
