  • SQLSTATE: HY000

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

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

ORA-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.

  • Cause: The statement lists duplicate privileges.

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

  • Error code in OceanBase Database: 4362

  • SQLSTATE: HY000

  • Cause: NOAUDIT does not allow the BY ACCESS or BY SESSION clause.

ORA-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));
    

ORA-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.

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

  • Error code in OceanBase Database: 4262

ORA-01724: floating point precision is out of range (1 to 126)

  • Error code in OceanBase Database: 4356

  • SQLSTATE: HY000

  • Cause: The floating-point precision exceeds the range of 1 to 126.

  • Solution: Use a correct floating-point precision.

ORA-01727: numeric precision specifier is out of range (1 to 38)

  • Error code in OceanBase Database: 4357

  • SQLSTATE: HY000

  • Cause: The numeric precision exceeds the range of 1 to 38.

  • Solution: Use a correct numeric precision.

ORA-01728: numeric scale specifier is out of range (-84 to 127)

  • Error code in OceanBase Database: 4358

  • SQLSTATE: HY000

  • Cause: The numeric scale exceeds the range of -84 to 127.

  • Cause: No database link name exists behind the at sign (@).

ORA-01730: invalid number of column names specified

  • Error code in OceanBase Database: 5242

  • SQLSTATE: HY000

  • Cause: The number of column names defined in the view is different from the number of output columns returned by the query that defines the view.

  • Solution: Modify the view definition to ensure that the number of column names in the view is the same as the number of output columns returned by the query.

ORA-01731: circular view definition encountered

  • Error code in OceanBase Database: 5239

  • SQLSTATE: 42S02

  • Cause: A circular view is defined.

ORA-01732: data manipulation operation not legal on this view

  • Error code in OceanBase Database: 5714

  • SQLSTATE: HY000

  • Cause: The data manipulation operation on this view is invalid.

ORA-01733: virtual column not allowed here

  • Error code in OceanBase Database: 5715

  • SQLSTATE: HY000

  • Cause: Virtual columns are present.

ORA-01741: illegal zero-length identifier

  • Error code in OceanBase Database: 5854

ORA-01743: only pure functions can be indexed

  • Error code in OceanBase Database: 5905

  • SQLSTATE: HY000

  • Cause: The SYSDATE or user environment is used in the index function.

  • Solution: PL functions must be pure functions such as RNDS, RNPS, WNDS, and WNPS.

ORA-01744: inappropriate INTO

  • Error code in OceanBase Database: 5617

ORA-01749: you may not GRANT/REVOKE privilege to/from yourself

  • Error code in OceanBase Database: 5384

  • SQLSTATE: HY000

  • Cause: You are attempting to grant privileges to yourself or revoke your own privileges, which is not allowed.

ORA-01750: UPDATE/REFERENCES may only be REVOKEd from the whole table, not by column

  • Error code in OceanBase Database: 5923

  • SQLSTATE: HY000

  • Cause: The UPDATE or REFERENCES operation can be revoked only from the entire table but not by column.

ORA-01752: cannot delete from view without exactly one key-preserved table

  • Error code in OceanBase Database: 5721

  • SQLSTATE: HY000

  • Cause: The deleted table may have the following problems:

    • The table does not contain key-preserved tables.

    • The table contains multiple key-preserved tables.

    • The key-preserved table is an unmerged view.

  • Solution: Redefine the view or delete the view from the base table.

ORA-01758: table must be empty to add mandatory (NOT NULL) column

  • Error code in OceanBase Database: 5946

  • SQLSTATE: HY000

  • Cause: A mandatory (NOT NULL) column can be added only to an empty table.

ORA-01760: illegal argument for function

  • Error code in OceanBase Database: 5728

  • SQLSTATE: HY000

  • Cause: The function contains invalid arguments.

ORA-01765: specifying owner's name of the table is not allowed

  • Error code in OceanBase Database: 5731

  • Cause: The UPDATE ... SET expression must be a subquery.

ORA-01776: cannot modify more than one base table through a join view

  • Error code in OceanBase Database: 5716

  • SQLSTATE: HY000

  • Cause: A column that belongs to multiple base tables is inserted or updated.

  • Solution: Split the statement into two or more independent statements.

ORA-01779: cannot modify a column which maps to a non key-preserved table

  • Error code in OceanBase Database: 5722

  • SQLSTATE: HY000
