ROLLBACK

This statement reverts all changes in the current transaction inside of TIDB. It is the opposite of a COMMIT statement.

Synopsis

RollbackStmt:

RollbackStmt

Examples

mysql> CREATE TABLE t1 (a INT NOT NULL PRIMARY KEY);

mysql> BEGIN;
Query OK, 0 rows affected (0.00 sec)

mysql> INSERT INTO t1 VALUES (1);
Query OK, 1 row affected (0.00 sec)

mysql> ROLLBACK;
Query OK, 0 rows affected (0.01 sec)

mysql> SELECT * FROM t1;
Empty set (0.01 sec)

MySQL compatibility

This statement is partly compatible with MySQL. TiDB only has syntactic support for CompletionTypeWithinTransaction. Closing the connection or continuing to open a new transaction after the transaction is rolled back is not supported. Any compatibility differences should be reported via an issue on GitHub.
