Applicability

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

OBE-01543: tablespace '%.*s' already exists

  • Error code in OceanBase Database: 4353

  • SQLSTATE: HY000

  • Cause: A tablespace with the specified name already exists.

  • Solution: Change the name of the tablespace to be created.

OBE-01555: snapshot too old

  • Error code in OceanBase Database: 4138

  • SQLSTATE: HY000

  • Cause: The rollback records required by the reader for consistency reads are overwritten by other compilers.

  • Solution: Change the value of undo_retention to extend the range of rollback records.

OBE-01700: duplicate username in list

  • Error code in OceanBase Database: 5381

  • SQLSTATE: HY000

  • Cause: The username is duplicate with an existing one.

OBE-01702: a view is not appropriate here

  • Error code in OceanBase Database: 5901

  • SQLSTATE: HY000

  • Cause: You are attempting to define EDITIONING_VIEW in a view.

  • Solution: Create EDITIONING_VIEW in a base table.

OBE-01705: an outer join cannot be specified on a correlation column

  • Error code in OceanBase Database: 5622

  • SQLSTATE: HY000

  • Cause: You cannot specify an OUTER JOIN operator (+) on a correlated column.

OBE-01711: duplicate privilege listed

  • Error code in OceanBase Database: 4349

  • SQLSTATE: HY000

  • Cause: The statement lists duplicate privileges.

OBE-01718: BY ACCESS | SESSION clause not allowed for NOAUDIT

  • Error code in OceanBase Database: 4362

  • SQLSTATE: HY000

  • Cause: The BY ACCESS or BY SESSION clause is specified in the NOAUDIT statement.

  • Solution: Delete the BY ACCESS or BY SESSION clause.

OBE-01719: outer join operator (+) not allowed in operand of OR or IN

  • Error code in OceanBase Database: 5623

  • SQLSTATE: HY000

  • Cause: The OR clause contains an OUTER JOIN operator (+).

  • Solution: If A and B are predicates, you can try the following method to obtain the effect of (A(+) or B):

    SELECT WHERE (A(+) AND NOT B)) UNION ALL (SELECT WHERE (B));
    

OBE-01720: grant option does not exist for '%.*s.%.*s'

  • Error code in OceanBase Database: 5371

  • SQLSTATE: HY000

  • Cause: A grant is being performed on a view, or the view is being replaced, but the underlying object does not have the grant option.

  • Solution: Obtain the grant options of all underlying objects in the view, or revoke the current grant on the view.

OBE-01722: invalid number: '%.*s'

  • Error code in OceanBase Database: 4262

  • SQLSTATE: 01000

  • Cause: The specified number is invalid.

  • Solution: Specify a valid number.

OBE-01722: invalid number

  • Error code in OceanBase Database: 5085

  • SQLSTATE: 22000

  • Cause: The specified number is invalid.

  • Solution: Specify a valid number.

OBE-01722: invalid number char '%c'

  • Error code in OceanBase Database: 5114
