Purpose
Commit changes made during a transaction and close the transaction
Syntax
BEGIN TRANSACTION [<transaction>]
<statements>
END TRANSACTION [<transaction>]
See Also
BEGIN TRANSACTION, COMMIT, ROLLBACK, SAVE TRANSACTION, SAVEPOINT, SET TRANSACTION, TXNISOLATION(), TXNLEVEL()
Description
The BEGIN TRANSACTION statement is used to flag the beginning of a transaction. The END TRANSACTION statement is used to commit changes made during the transaction and close the transaction. The COMMIT statement and the ROLLBACK statement can also be used to close a transaction. The COMMIT statement will save the changes made and the ROLLBACK statement will discard the changes made.
Transactions can be nested by issuing a second or subsequent BEGIN TRANSACTION before an existing transaction has been closed. The TXNLEVEL() function returns the current transaction nesting level. When a transaction is closed, transactions nested within it are also closed.
Savepoints can be set during a transaction. These identify stages within the transaction which can subsequently be used as ROLLBACK points.
The optional <transaction> is a name for the transaction. This name can be used by the COMMIT and ROLLBACK statements.
Example
BEGIN TRANSACTION trans1 INSERT INTO customer; (TITLE, LAST_NAME, FIRST_NAME, INITIAL, STREET,; CITY, STATE, ZIP,LIMIT, START_DATE); VALUES; ('Ms', 'Jones', 'Susan', 'B', '177 High Street','Beverly', 'MA', '01915', 2000, date()) INSERT INTO accounts (ORD_VALUE) VALUES (30) BEGIN TRANSACTION trans2 INSERT INTO accounts (ORD_VALUE) VALUES (60) // Rollback the trans1 transaction and any transactions // nested in trans1 ROLLBACK TRANSACTION trans1 END TRANSACTION
