The label for a column heading consists of three 20-byte segments. Interactive SQL, the Query/400 program, IBM DB2 Query Manager and SQL Development Kit for iSeries, and other products can display or print each 20-byte segment on a separate line. If the label for a column contains mixed data, each 20-byte segment must be a valid mixed data character string. The shift characters must be paired within each 20-byte segment.
