Transaction Management
By default, autocommit is turned off, which means each transaction consists of multiple statements ended by either a COMMIT or ROLLBACK statement.
If an error occurs during the execution of an SQL statement, the default is to roll back the statement. You can change this behavior and roll back the entire transaction if an error occurs by issuing SET SESSION WITH ON_ERROR = ROLLBACK TRANSACTION.
To determine the current status of transaction error handling, issue the SELECT DBMSINFO('ON_ERROR_STATE') statement.
