/images/arrow_right.png IDRGValidator::WildCharacter property space
Get and Set the "match any single character" wildcard character for SQL queries.
You can use this property if you have ported the original DRG database into another database, which uses a different wild character for the queries. The default match-single-character wildcard character is the underscore symbol (_). With the drgValidator module you can always formulate a query using the question mark (?) as a wildcard, as in each query string a ? is replaced by the wildcard character specified by this property before execution.
