Without the OnOff
parameter, this function returns auto-commit status for connection_id. TRUE is returned if auto-commit is on,
FALSE if it is off or an
error occurs.
If OnOff is TRUE, auto-commit is enabled, if it is
FALSE auto-commit is
disabled. Returns TRUE on
success, FALSE on
failure.
By default, auto-commit is on for a connection.
Disabling auto-commit is equivalent with starting a
transaction.

odbc_rollback().
