Aborts the current transaction.
The current transaction is aborted. No database alterations requested in the transaction build-up are executed.
All cursors opened by the current connection are closed.
If there is no currently active transaction, any cursors opened by the current ident are closed, but the ROLLBACK statement is otherwise ignored. No error code is returned in this case.
When a BACKUP transaction is rolled back, all files created with CREATE BACKUP are deleted.
The ROLLBACK statement cannot be used in a result-set procedure.
The ROLLBACK statement cannot be used within an atomic compound SQL statement, see COMPOUND STATEMENT.
The ROLLBACK BACKUP statement must be used to abort a BACKUP transaction.
The ROLLBACK BACKUP statement is not supported in procedural usage contexts.
See the Mimer SQL Programmer's Manual, Transaction Handling and Database Security, for a more detailed discussion of transaction handling.
Exampleexec sql INSERT INTO sometable VALUES (:hv1, :hv2...); if SQLSTATE = "00000" then exec sql COMMIT; else exec sql ROLLBACK; end if;
