Parameters
| Parameter | Description |
|---|---|
| WORK | This parameter is optional and is provided for compatibility with SQL standards. The COMMIT; statement is equivalent to the COMMIT WORK; statement. |
| COMMENT | Commits the current transaction and associates a comment with it. This comment can help you diagnose faults of the distributed transaction. Note: If the distributed transaction cannot be committed due to a network or server fault, OceanBase Database will store the comment and transaction ID in the data dictionary. The comment indicates the faulty application and provides information for contacting the DBA that commits the transaction. |
