Applicability

This topic applies only to OceanBase Database Enterprise Edition. OceanBase Database Community Edition provides only MySQL mode.

ORA-20000: The stored procedure 'raise_application_error' was called which causes this error to be generated", "ORA%06ld: %.*s

  • Error code in OceanBase Database: 20000

  • SQLSTATE: HY000

  • Cause: The error code of RAISE_APPLICATION_ERROR defined by the stored procedure is called.

  • Solution: Fix the problem based on the description in the error message, or contact the application administrator or database administrator for more information.

ORA-21000: error number argument to raise_application_error of stringstring is out of range

  • Error code in OceanBase Database: 21000

  • SQLSTATE: HY000

  • Cause: The error code of RAISE_APPLICATION_ERROR is out of range.

ORA-21560: argument %.*s is null, invalid, or out of range

  • Error code in OceanBase Database: 5934

  • SQLSTATE: HY000

  • Cause: The passed argument value is NULL, invalid, or out of range. For example, the value of the LOB/FILE positional or size argument exceeds the range of 1 to (4 GB – 1), or files are opened in invalid open modes.

  • Solution: Check and correct the program to ensure that no NULL, invalid, or out-of-range value is passed.

ORA-22003: value is out of range

  • Error code in OceanBase Database: 4157

  • SQLSTATE: 22003

  • Cause: An unexpected communication error occurred while executing the specified TCP/IP function func. The return code of the TCP/IP function is rc, and the argument of the func function is parm.

  • Solution: Contact OceanBase Technical Support for troubleshooting.

ORA-22369: invalid parameter encountered in method %s

  • Error code in OceanBase Database: 5955

  • SQLSTATE: HY000

  • Cause: An invalid parameter is being passed to SYS, including SYS.AnyType, SYS.AnyData, and SYS.AnyDataSet.

  • Solution: Check the parameters being passed and make sure that the parameters are allowed.

Note

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

ORA-22370: incorrect usage of method %s

  • Error code in OceanBase Database: 5956

  • SQLSTATE: HY000

  • Cause: SYS.AnyType, SYS.AnyData, or SYS.AnyDataSet is being used inappropriately.

  • Solution: Make sure that the usage is correct.

Note

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

ORA-22625: OCIAnyData is not well-formed

  • Error code in OceanBase Database: 5965

  • SQLSTATE: HY000

  • Cause: You attempted to use OCIAnyData without initializing or constructing it.

  • Solution: Use OCIAnyDataBeginConstruct to initialize the handle before attributes are added. Use OCIAnyDataEndConstruct to complete the construction. Alternatively, use OCIAnyDataConvert to perform the construction. Make sure that OCIAnyData is properly constructed before it accesses attributes.

Note

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

ORA-22626: Type Mismatch while constructing or accessing OCIAnyData

  • Error code in OceanBase Database: 5957

  • SQLSTATE: HY000

  • Cause: The provided type did not match the type of AnyData. If the operation is attempting to do piecewise construction or access, the type provided does not match the type of the current attribute.

  • Solution: Make sure that the type provided matches the type of object to be constructed or accessed.

Note

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

ORA-22627: tc [%s] must be that of object/varray/nested table

  • Error code in OceanBase Database: 5966

  • SQLSTATE: HY000

  • Cause: The type code is not that of the object/varray/nested table.

  • Solution: Make sure that the type code is OCI_TYPECODE_OBJECT, OCI_TYPECODE_VARRAY, or OCI_TYPECODE_TABLE.

Note

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

ORA-22806: not an object or REF

  • Error code in OceanBase Database: 5477
  • SQLSTATE: 42000
  • Cause: The item is neither an object nor a REF.
  • Solution: Use an object or REF and retry the operation.

ORA-22816: unsupported feature with RETURNING clause

  • Error code in OceanBase Database: 9573

  • SQLSTATE: HY000

  • Cause: The object type column does not support the RETURNING clause, LONG column, remote tables, and INSERT and INSTEAD OF triggers with subqueries.

  • Solution: Use independent statements to obtain values.

Note

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

ORA-22903: MULTISET expression not allowed

  • Error code in OceanBase Database: 9716
  • SQLSTATE: HY000
