The encapsulation of Data Definition Language (DDL) by the DB Interface Module allows the creation of national character set columns when defining new tables. The public enum ValueType, from class RWDBValue, is used by class RWDBColumn to specify the type of a column. When creating a table, specifying a column type of RWDBValue::UString, RWDBValue::MBString, or RWDBValue::WString results in a national character set column type. Please see your Access Module User Guide for more information on the SQL type to which these RWDBValue types map.
