After updating the royaltyper entries for the two authors, insert the savepoint percentchanged, then determine how a 10 percent increase in the book’s price would affect the authors’ royalty earnings. The transaction is rolled back to the savepoint with the rollback transaction command:
begin transaction royalty_change update titleauthor set royaltyper = 65 from titleauthor, titles where royaltyper = 75 and titleauthor.title_id = titles.title_id and title = "The Gourmet Microwave" update titleauthor set royaltyper = 35 from titleauthor, titles where royaltyper = 25 and titleauthor.title_id = titles.title_id and title = "The Gourmet Microwave" save transaction percentchanged update titles set price = price * 1.1 where title = "The Gourmet Microwave" select (price * total_sales) * royaltyper from titles, titleauthor where title = "The Gourmet Microwave" and titles.title_id = titleauthor.title_id rollback transaction percentchanged commit transaction
Define a transaction by enclosing SQL statements and/or system procedures with the phrases begin transaction and commit. If you set the chained transaction mode, Adaptive Server implicitly invokes a begin transaction before the following statements: delete, insert, open, fetch, select, and update. You must still explicitly enclose the transaction with a commit.
If no transaction is currently active, the commit or rollback statement has no effect on Adaptive Server.
ANSI SQL – Compliance level: Entry-level compliant.
The commit transaction and commit tran forms of the statement are Transact-SQL extensions.
