RELEASE SAVEPOINT

Destroys the specified savepoint in the current transaction.

Syntax

RELEASE SAVEPOINT spname

spname is the savepoint identifier.

Usage

Use the RELEASE SAVEPOINT instruction to delete a savepoint defined by the SAVEPOINT instruction. See database documentation for more details about the behavior of this SQL statement. Note for example that IBM^® Informix^® IDS will also release any savepoint that has been declared between the specified savepoint and the RELEASE SAVEPOINT instruction.

Example

In the next example, the RELEASE SAVEPOINT instruction cancels the UPDATE and INSERT statements and destroys the sp1 and sp2 savepoints. Only the DELETE statement will take effect at the end of the transaction:

MAIN
  DATABASE stock
  BEGIN WORK
  DELETE FROM items
  SAVEPOINT sp1
  INSERT INTO items VALUES ( ... )
  SAVEPOINT sp2
  UPDATE items SET ...
  RELEASE SAVEPOINT sp1
  ROLLBACK WORK TO SAVEPOINT
  COMMIT WORK
END MAIN
