UPT provides the following functionality in Pass Through sessions:
  • Proper storage of all assigned and unassigned Unicode characters from U+0000 to U+10FFFD.
  • Ability to store PTCs in Unicode columns as data and retrieve it as entered. For example:
    INSERT INTO currency (U&'#20BD' UESCAPE '#');
  • Ability to use PTCs in queries. For example:
    SELECT feed FROM twitter WHERE feed LIKE U&'%#+01F602%' UESCAPE '#';
  • Noncharacters and ill-formed code unit sequences are changed to the REPLACEMENT CHARACTER (U+FFFD) which can pass through and be stored in Teradata.

With UPT enabled, users can expect translation errors to be reduced or eliminated.
