Applicability

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

OBE-00000: PX DOP downgrade from %ld to %ld

  • OceanBase error code: 5780

  • SQLSTATE: HY000

  • OceanBase error code: 5024

  • SQLSTATE: 23000

  • Cause: An UPDATE or INSERT statement is attempting to insert a duplicate key.

  • Solution: Remove the UNIQUE constraint or do not insert this key.

OBE-00001: unique constraint (%.*s) violated

  • OceanBase error code: 5595

  • SQLSTATE: 23000

  • Cause: An UPDATE or INSERT statement is attempting to insert a duplicate key.

  • Solution: Remove the UNIQUE constraint or do not insert this key.

OBE-00001: unique constraint violated, column '%.*s' with value '%.*s' in %s

  • OceanBase error code: 5334

  • SQLSTATE: HY000

  • Cause: An UPDATE or INSERT statement is attempting to insert a duplicate key.

  • Solution: Remove the UNIQUE constraint or do not insert this key.

OBE-00001: unique constraint (%.*s) violated

  • OceanBase error code: 5562

  • SQLSTATE: HY000

  • Cause: An UPDATE or INSERT statement is attempting to insert a duplicate key.

OBE-00036: maximum number of recursive SQL levels (%ld) exceeded

  • OceanBase error code: 9697

  • SQLSTATE: HY000

  • Cause: You are attempting to go more than the specified number of recursive SQL levels.

  • Solution: Remove the recursive SQL or the recursive trigger.

Note

This error code is introduced since OceanBase Database V4.0.0.

OBE-00051: timeout occurred while waiting for a resource

  • OceanBase error code: 5848

  • SQLSTATE: HY000

  • Cause: The error is usually caused by dead instances.

  • OceanBase error code: 6006

  • SQLSTATE: HY000

  • Cause: The resource is busy.

  • Solution: Try again or increase the timeout period.

OBE-00185: invalid argument for %s call

  • OceanBase error code: 5488
  • SQLSTATE: HY000
  • Cause: The %s call contains an invalid argument.

Note

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

  • OceanBase error code: 6005
  • SQLSTATE: HY000
  • Cause: The update operation failed to add a lock. This error is returned to the upper layer, and the system retries the operation.
  • Solution: This is an internal error code. Contact OceanBase Technical Support for troubleshooting.

Note

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

OBE-00060: internal error code, arguments: -4012, Timeout, query has reached the maximum query timeout: %ld(us), maybe you can adjust the session variable ob_query_timeout or query_timeout hint, and try again

  • OceanBase error code: 4012
  • SQLSTATE: HY000
  • Cause: The execution timed out.
  • Solution:
    • Reduce the amount of time required through performance tuning.
    • Extend the timeout period.
    • Contact OceanBase Technical Support for troubleshooting.

Note

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

OBE-00060: internal error code, arguments: -4013, No memory or reach tenant memory limit

  • OceanBase error code: 4013
  • SQLSTATE: HY000
  • Cause: Memory allocation failed.

    • OceanBase error code: 5683

    • SQLSTATE: HY000

    • Cause: The function contains excessive arguments.

    OBE-00942: table or view \'%s.%s\'does not exist

    • OceanBase error code: 5019

    • SQLSTATE: 42S02

    • Cause: The table or view does not exist. In OceanBase Database V2.2.70 and later, role privileges are added. If the current role does not have the SELECT privilege on some tables or views, this error is returned.

    • Solution: Check the spelling of the SQL statement. In particular, check the privileges of the current role in OceanBase Database V2.2.70 and later.

    OBE-00942: table or view '%.*s' does not exist

    • OceanBase error code: 5201

    • SQLSTATE: 42S02

    • Cause: The table or view does not exist. In OceanBase Database V2.2.70 and later, role privileges are added. If the current role does not have the SELECT privilege on some tables or views, this error is returned.

    • Solution: Check the spelling of the SQL statement. In particular, check the privileges of the current role in OceanBase Database V2.2.70 and later.

    OBE-00957: duplicate column name

    • OceanBase error code: 4228

    • SQLSTATE: 42000

    • Cause: The column to be created already exists.

    OBE-00959: tablespace '%.*s' does not exist

    • OceanBase error code: 4354

    • SQLSTATE: HY000

    • Cause: The tablespace does not exist.

    OBE-00964: table name not in FROM list

    • OceanBase error code: 5490
    • SQLSTATE: 42000
    • Cause: The table name is not in the FROM list.
    • Solution: Make sure that the name entered is a correct table name and is in the FROM list.

    Note

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

    OBE-00969: missing ON keyword

    • OceanBase error code: 5370

    • SQLSTATE: HY000

    • Cause: The ON keyword is missing.

    OBE-00972: identifier \'%.*s\' is too long

    • OceanBase error code: 5179

    • SQLSTATE: 42000

    • Cause: The specified identifier exceeds the maximum length.

    • Solution: Reduce the number of bytes of the specified identifier to less than the maximum length.

    OBE-00976: Specified pseudo column or operator not allowed here

    • OceanBase error code: 5763

    • SQLSTATE: HY000

    • Cause: The LEVEL, PRIOR, ROWNUM, CONNECT_BY_ROOT, CONNECT_BY_ISLEAF, and CONNECT_BY_ISCYCLE keyword are not allowed at the current location.

    • Solution: Delete the LEVEL, PRIOR, ROWNUM, CONNECT_BY_ROOT, CONNECT_BY_ISLEAF, and CONNECT_BY_ISCYCLE keyword.

    OBE-00979: not a GROUP BY expression

    • OceanBase error code: 5218

    • SQLSTATE: 42000

    • Cause: The expression is not a GROUP BY expression.

    OBE-00980: synonym translation is no longer valid

    • OceanBase error code: 5330

    • SQLSTATE: HY000

    • Cause: The synonym is not converted into a valid target object. The possible causes are as follows:

      • The target mode does not exist.

      • The target object does not exist.

      • The synonym specifies an incorrect database link.

      • The synonym specifies a target object for versioning but does not perform versioning.

    • Solution: Modify the definition of the synonym so that the synonym points to a valid object.

    OBE-00984: column not allowed here

    • OceanBase error code: 5942

    • SQLSTATE: HY000

    • Cause: This column cannot be inserted here.

    OBE-00988: missing or invalid password(s)

    • OceanBase error code: 5887

    • SQLSTATE: HY000

    • Cause: The password is incorrect.

    OBE-00989: Cursor Variable in record, object, or collection is not supported by this release

    • OceanBase error code: 9811
    • SQLSTATE: HY000
    • Cause: The current version does not support nesting cursor variables within records, objects, or collections.
    • Solution: Avoid nested cursor structures.

    OBE-00998: must name this expression with a column alias

    • OceanBase error code: 5872

    • SQLSTATE: HY000

    • Cause: The expression must be named with a column alias.
