In this example, the Unicode values in the Description column are compressed using the LZCOMP function with ALC. The LZDECOMP function uncompresses the previously compressed values.

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