Character Based Functions - Example
Assume that NAME is a VARCHAR(128) column, encoded in Unicode
UTF-8, that contains 'Jürgen'. The following query:
SELECT CHARACTER_LENGTH(NAME,CODEUNITS32)
FROM T1 WHERE NAME = ’Jürgen’;
or
SELECT CHARACTER_LENGTH(NAME,CODEUNITS16)
FROM T1 WHERE NAME = ’Jürgen’;
returns the value 6. A similar query:
SELECT CHARACTER_LENGTH(NAME,OCTETS)
FROM T1 WHERE NAME = ’Jürgen’;
or
SELECT LENGTH(NAME)
FROM T1 WHERE NAME = ’Jürgen’;
returns the value 7.
