     <function>ingres_query</function> sends the given
     <parameter>query</parameter> to the Ingres server. This query
     must be a valid SQL query (see the Ingres SQL reference guide)
    </para>
    <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 immediatly commited.
    </para>
    <para>
     Some types of SQL queries can't be sent with this function:
