   <function>ingres_query</function> sends the given

  <para>
   The query becomes part of the currently open transaction.  If
   there is no open transaction, <function>ingres_query</function>
   opens a new transaction. To close the transaction, you can either
   call <function>ingres_commit</function> to commit the changes
   made to the database or <function>ingres_rollback</function> to
   cancel these changes. When the script ends, any open transaction
   is rolled back (by calling
   <function>ingres_rollback</function>). You can also use
   <function>ingres_autocommit</function> before opening a new
   transaction to have every SQL query immediately committed.
