16.20 - Example: Using STRING_CS to Translate a KANJI1 String to UNICODE - Advanced SQL Engine - Teradata Database

Consider the SysNames table from the preceding example, “Example: Using STRING_CS to Determine the Client Character Set.”

The following statement uses STRING_CS to determine which encoding to use to translate strings in the SysName column from the KANJI1 server character set to the UNICODE server character set:

   SELECT CASE STRING_CS(SysName)
      WHEN 0 THEN TRANSLATE(SysName USING KANJI1_SBC_TO_UNICODE)
      WHEN 1 THEN TRANSLATE(SysName USING KANJI1_KANJIEBCDIC_TO_UNICODE)
      WHEN 2 THEN TRANSLATE(SysName USING KANJI1_KANJIEUC_TO_UNICODE)
      WHEN 3 THEN TRANSLATE(SysName USING KANJI1_KANJISJIS_TO_UNICODE)
      ELSE TRANSLATE(SysName USING KANJI1_SBC_TO_UNICODE)
      END
   FROM SysNames;
