      Description

      SQL>comment on table json_test is 'table''s comment for ansi json support test';

          • ERROR[15005] Unmatched quote in input (unterminated string):
            insert into TRAFODION."MD".TEXT values (1802720017000399316, 3, 0, 0, 0, 'table's comment for ansi json support test') ; [2018-02-26 18:02:46]

       

      So quotes in string 'table''s comment for ansi json support test' is escaped twice, because we have a Insert statement within Comment-On statement.

       

      And statement below works fine:

      SQL>comment on table json_test is 'table''''s comment for ansi json support test';

      — SQL operation complete.

      SQL>showddl json_test;
      CREATE TABLE TRAFODION.JSON.JSON_TEST
      (
      K INT DEFAULT NULL NOT SERIALIZED
      , J VARCHAR(200) CHARACTER SET ISO88591
      COLLATE DEFAULT DEFAULT NULL NOT SERIALIZED
      )
      ATTRIBUTES ALIGNED FORMAT
      ;

      COMMENT ON TABLE TRAFODION.JSON.JSON_TEST IS 'table's comment for ansi json
      support test' ;

      — SQL operation complete.
