What Happens to the Current Transaction If a DDL Statement Is Executed?

If a DDL statement is executed, the current transaction will be committed and ended. All the
database changes made in the current transaction will become permanent. This is called an
implicit commit by a DDL statement. The following tutorial exercise shows you that the CREATE
TABLE statement forced the current transaction to be committed and ended. The subsequent
ROLLBACK statement has no effects on the closed transaction.
SQL> connect HR/fyicenter
SQL> INSERT INTO fyi_links (url, id) VALUES ('oracle.com', 112);
SQL> INSERT INTO fyi_links (url, id) VALUES ('sql.com', 113);

Table created.
SQL> ROLLBACK;
Rollback complete.
