[jira] [Created] (CALCITE-5664) Support CONVERT function with "USING" keyword

ZheHu created CALCITE-5664:
------------------------------

             Summary: Support CONVERT function with "USING" keyword
                 Key: CALCITE-5664
                 URL: https://issues.apache.org/jira/browse/CALCITE-5664
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.34.0
            Reporter: ZheHu
            Assignee: ZheHu


After CALCITE-111, we now support CONVERT(charValue, srcCharsetName, destCharsetName) that works on converting character sets.
CONVERT(charValue USING transcodingName) also fits the SQL standard, and MySQL has  implement it. For example:
 * select convert('employ_id' using utf16) as alia from employee

Noted: Calcite already supports this from the parser.
