SAVEPOINT
Purpose
Identifies a stage within a transaction which can subsequently be used as ROLLBACK point.
Syntax
SAVEPOINT <savepoint>
See Also
BEGIN TRANSACTION, COMMIT, END TRANSACTION, ROLLBACK, SAVE TRANSACTION, SET TRANSACTION, TXNISOLATION(), TXNLEVEL()
Description
The SAVEPOINT statement identifies a stage within a transaction which can subsequently be used as ROLLBACK point. The name of the savepoint is specified in <savepoint>.
Issuing the SAVEPOINT <savepoint> statement causes the TXNLEVEL() to increase by 1. If the transaction is rolled back to the <savepoint> using the ROLLBACK command, the TXNLEVEL will decrease by 1 and a partial rollback of the transaction will be carried out. Changes made since the specified <savepoint> was declared are discarded and the transaction continues from the <savepoint>.
A transaction is a sequence of SQL statements that Recital treats as a single unit. A transaction begins with the first executable SQL statement after a BEGIN TRANSACTION. A transaction ends with a COMMIT, ROLLBACK or END TRANSACTION.
Example
BEGIN TRANSACTION parent_and_child 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()) SAVEPOINT parent_added INSERT INTO accounts (ORD_VALUE) VALUES (30) ROLLBACK TRANSACTION parent_added END TRANSACTION
