Input masks are especially useful for dates because conventions vary in different regions. For example, applying an input mask for the date in the European format (DD-MM-YYYY) means dates can’t be entered in your database in other formats. You can apply an input mask to columns in tables, query result sets, and to controls on forms or reports.
