# Autocommit

#### Syntax

    AUTOCOMMIT { ON | OFF }

#### Description

Turns the connection's auto-commit mode on or off. JDBC specifies that the default auto-commit mode is `ON`. Certain types of processing require that auto-commit mode be `OFF`. For information about auto-commit, see the Derby Developer's Guide.

If auto-commit mode is changed from off to on when there is a transaction outstanding, that work is committed when the current transaction commits, not at the time auto-commit is turned on. Use Commit or Rollback before turning on auto-commit when there is a transaction outstanding, so that all prior work is completed before the return to auto-commit mode.

#### Example

    ij> autocommit off;
    ij> DROP TABLE menu;
    0 rows inserted/updated/deleted
    ij> CREATE TABLE menu (course CHAR(10), item CHAR(20), price INT);
    0 rows inserted/updated/deleted
    ij> INSERT INTO menu VALUES ('entree', 'lamb chop', 14),
    ('dessert', 'creme brulee', 6),
    ('appetizer', 'baby greens', 7);
    3 rows inserted/updated/deleted
    ij> commit;
    ij> autocommit on;
    ij>
