ERROR 5934 (HY000): fetch out of sequence

  • OceanBase error code: 5934

  • SQLSTATE: HY000

  • Cause: The operation attempted to fetch data from an invalid cursor. Possible causes:

    • The data is fetched from the cursor after the retrieval reaches the last line and the ORA-1403 error is returned.

    • The FOR UPDATE clause is used to open the cursor, and then the data is fetched after the COMMIT statement is issued.

    • All placeholders in the SQL statement are re-bound, and the data is fetched before the statement is re-executed.

    Note

    This error can also occur if a PL cursor is circularly and implicitly fetched.

  • Solution:

    • Do not issue the FETCH statement after the retrieval reaches the last line.

    • After you use the FOR UPDATE clause to open the cursor, do not fetch the data after you issue the COMMIT statement.

    • Bind placeholders again, execute the SQL statement, and then fetch the data.

ERROR 5959 (HY000): invalid SIZE specified
