In this example, the Latin values in the Description column are compressed using the CAMSET_L function with ALC. The DECAMSET_L function uncompresses the previously compressed values.

CREATE MULTISET TABLE Pendants
   (ItemNo INTEGER,
    Gem CHAR(10) UPPERCASE CHARACTER SET LATIN,
    Description VARCHAR(1000) CHARACTER SET LATIN
       COMPRESS USING TD_SYSFNLIB.CAMSET_L
       DECOMPRESS USING TD_SYSFNLIB.DECAMSET_L);
