LeftJoin caries out a left join to another ArrData object or a TableData object (to bring in fields from matching records). It is possible to match on any number of fields (which are specified in the JoinFields parameter). It then brings in the required fields (specified in the CopyFields parameter) which must be present in the ArrData object, or all fields with matching names if none are specified. All matched and required fields must have the same name in both objects (use Rename if necessary).
