START TRANSACTION | TiDB SQL Statement Reference |
An overview of the usage of START TRANSACTION for the TiDB database. |
reference |
This statement starts a new transaction inside of TiDB. It is similar to the statements BEGIN and SET autocommit=0.
In the absence of a START TRANSACTION statement, every statement will by default autocommit in its own transaction. This behavior ensures MySQL compatibility.
BeginTransactionStmt:
mysql> CREATE TABLE t1 (a int NOT NULL PRIMARY KEY);
Query OK, 0 rows affected (0.12 sec)
mysql> START TRANSACTION;
Query OK, 0 rows affected (0.00 sec)
mysql> INSERT INTO t1 VALUES (1);
Query OK, 1 row affected (0.00 sec)
mysql> COMMIT;
Query OK, 0 rows affected (0.01 sec)This statement is understood to be fully compatible with MySQL. Any compatibility differences should be reported via an issue on GitHub.
