   Executes an SQL statement given by the <parameter>query</parameter> against
   a given database handle (specified by the <parameter>dbhandle</parameter> 
   parameter).
  </para>
  <para>
   This function will return a boolean result; &true; for success or &false; for failure.
   If you need to run a query that returns rows, see <function>sqlite_query</function>.
  </para>
  <warning>
   <simpara>
    SQLite <emphasis>will</emphasis> execute multiple queries separated by
    semicolons, so you can use it to execute a batch of SQL that you have
    loaded from a file or have embedded in a script.
