Purpose
Defines the completion of an explicit Teradata session mode transaction, commits the transaction, and drops its Transient Journal.
An explicit Teradata session mode transaction must always start with a BEGIN TRANSACTION statement, and you must always specify both BEGIN TRANSACTION and END TRANSACTION statements to define the limits of an explicit transaction in Teradata session mode.
See BEGIN TRANSACTION for additional usage information about END TRANSACTION.
Required Privileges
None.
Syntax
ANSI Compliance
END TRANSACTION is a Teradata extension to the ANSI SQL:2011 standard.
The statement is valid only in Teradata session mode. If you submit an END TRANSACTION statement in ANSI session mode, Teradata Database aborts the request and returns an error.
For ANSI session mode transaction control statements, see COMMIT and ROLLBACK.
BEGIN TRANSACTION/END TRANSACTION Pairs and Explicit Transactions
When you code an explicit transaction in Teradata session mode, you must initiate the transaction with a BEGIN TRANSACTION statement and complete it with an END TRANSACTION statement. See BEGIN TRANSACTION.
END TRANSACTION and Multistatement Requests
There can be no more than one END TRANSACTION statement specified in a multistatement request, and that statement, if specified, must be the last statement in the request.
Differences Between the Effects of END TRANSACTION and ABORT or ROLLBACK
While an END TRANSACTION request terminates and commits a transaction and drops its Transient Journal, ABORT and ROLLBACK requests terminate a transaction with rollback. See ABORT and ROLLBACK.
In general, the rules for committing transactions using the COMMIT statement also apply to END TRANSACTION. See COMMIT.
Rules for END TRANSACTION Using Embedded SQL
- END TRANSACTION is valid only when you specify the TRANSACT(BTET) or -tr(BTET) options to the preprocessor. Otherwise, an error is returned and the precompilation fails.
- END TRANSACTION cannot be performed as a dynamic SQL statement.
- When END TRANSACTION is processed, the transaction, if not already aborted, is committed.
