Applicability

This topic applies only to the Oracle-compatible mode OceanBase Database.

OBE-02000: missing VALUE keyword

  • Error code in OceanBase Database: 5466
  • SQLSTATE: HY000
  • Cause: The VALUE keyword is missing.
  • Solution: Add the VALUE field to the expression.

Note

This error code is introduced since OceanBase Database V4.1.0.

OBE-02014: cannot select FOR UPDATE from view with DISTINCT GROUP BY etc

  • Error code in OceanBase Database: 5788

  • SQLSTATE: HY000

  • Cause: You are attempting to select FOR UPDATE from a view that is not merged. In practice, a view is not merged if a syntax (such as DISTINCT or GROUP BY) that prevents merging is used or parameter settings are inappropriate in the initialization file.

  • Solution: Identify the cause why the view is not merged and take corresponding measures so that the view can be merged.

OBE-02017: integer value required

  • Error code in OceanBase Database: 9671

  • SQLSTATE: HY000

  • Cause: Integer values are not used.

OBE-02019: connection description for remote database not found

  • Error code in OceanBase Database: 5835

  • SQLSTATE: HY000

  • Cause: No connection description is found for the remote database.

OBE-02021: DDL operations are not allowed on a remote database

  • Error code in OceanBase Database: 5095

  • SQLSTATE: HY000

  • Cause: You are attempting to perform DDL operations, such as CREATE TABLE tablename@remotedbname, on a remote database.

  • Solution: To modify the structure of a remote database, you must connect to the remote database and have the required privileges.

OBE-02024: database link not found

  • Error code in OceanBase Database: 5836

  • SQLSTATE: HY000

  • Cause: The database link to be deleted is not found in the dictionary.

  • Solution: Modify the database link name.

OBE-02049: timeout: distributed transaction waiting for lock

  • Error code in OceanBase Database: 6004

  • SQLSTATE: HY000

  • Cause: When the current statement reads a row of data being modified by another transaction that is being committed, the statement must wait until the transaction is committed and then determine whether to read the row of data. A timeout error is returned if the wait times out.

  • Solution: Query the [G]V$OB_TRANSACTION_PARTICIPANTS view for the transaction that is being committed. View the logs on the corresponding server based on the transaction ID to determine why the commit has not been completed.

OBE-02051: another session or branch in same transaction failed or finalized

  • Error code in OceanBase Database: 6264

  • SQLSTATE: HY000

  • Cause: Another session with the same global transaction ID at the same site failed. This error may also be caused by the following program error: When the database is updated, another tightly coupled transaction branch with the same global transaction ID is completed or terminated.

  • Solution: You do not need to take any actions because the transaction will automatically resume. If a program error occurred, ensure that the database is not updated once the transaction manager enables two-phase commit for tightly coupled distributed transactions.

Note

The exception indicated by this error code will not be captured by the PL exception handling mechanism in this version.

OBE-02089: COMMIT is not allowed in a subordinate session

  • Error code in OceanBase Database: 6258

  • SQLSTATE: XAE07

  • Cause: COMMIT is executed in a session that is not a global coordinator of two-phase commit.

  • Solution: Execute COMMIT only in global coordinator sessions.

OBE-02097: parameter cannot be modified because specified value is invalid

  • Error code in OceanBase Database: 4701 and 5855

  • SQLSTATE: HY000

  • Cause: The initialization parameter can be modified, but the modified value is invalid.

  • Solution: Check the value range of the parameter in the OceanBase Database Reference Guide of the corresponding version.

OBE-02149: Specified partition does not exist

  • Error code in OceanBase Database: 5146

  • SQLSTATE: HY000

  • Cause: The partition of the object is not found.

  • Solution: Use a correct partition name and retry.

OBE-02204: ALTER INDEX and EXECUTE not allowed for views

  • Error code in OceanBase Database: 5372

  • SQLSTATE: HY000

  • Cause: You are attempting to grant or revoke view operation privileges that are invalid for views.

  • Solution: Do not attempt to grant or revoke the ALTER, INDEX, or EXECUTE privilege on views.

OBE-02205: only SELECT and ALTER privileges are valid for sequences

  • Error code in OceanBase Database: 5364

  • SQLSTATE: HY000

  • Cause: You are attempting to grant or revoke a sequence operation privilege that is invalid for sequences.

  • Solution: Do not attempt to grant or revoke the DELETE, INDEX, INSERT, UPDATE, REFERENCES, or EXECUTE privilege on sequences.

OBE-02207: invalid INITRANS option value

  • Error code in OceanBase Database: 5724

  • SQLSTATE: HY000

  • Cause: The value of INITRANS is not an integer ranging from 1 to 255, and is not less than or equal to the value of MAXTRANS.

OBE-04091: table '%.*s'.' %.*s' is mutating, trigger/function may not see it

  • Error code in OceanBase Database: 5791

  • SQLSTATE: HY000

  • Cause: A trigger or a user-defined PL function referenced in this statement is attempting to view or modify a table while the statement that triggers the table is modifying this table.
