### 4.4.2 About Transactions in SQL Commands

Transactional mode is a stateful transaction mode where you can, for example, perform an update, select data for review, and `COMMIT` or `ROLLBACK` changes. It is implemented using `DBMS_JOBS`.

Consider the following behavior in transactional mode:

- Actions are not committed to the database until you enter an explicit `COMMIT` command.

- Exiting SQL Commands terminates and rolls back the current transaction.

- A session timeout terminates and rolls back the current transaction.

  Note that the Environment Setting, `SQL Commands Maximum Inactivity in minutes`, sets the time before an inactive session times out. The default timeout is 60 minutes.

- The CSV Export option is not available.

### 4.4.4 Terminating a Command

You can terminate a command in SQL Commands using a semicolon (;), a slash (/), or with nothing.

Consider the following valid alternatives:

    SELECT * from emp;

    SELECT * from emp
    /

    SELECT * from emp

The first example demonstrates the use of a semicolon (;), the second example demonstrates using a slash (/), and the final example demonstrates a command with no termination.
