  <para>
   The <function>maxdb_stmt_execute</function> function executes a query that has been previously
   prepared using the <function>maxdb_prepare</function> function represented by the
   <parameter>stmt</parameter> resource. When executed any parameter markers which exist will
   automatically be replaced with the appropiate data.
  </para>
  <para>
   If the statement is UPDATE, DELETE, or INSERT, the total number of affected rows can be
   determined by using the <function>maxdb_stmt_affected_rows</function> function. Likewise,
   if the query yields a result set the <function>maxdb_fetch</function> function is used.
  </para>
  <note>
   <para>
    When using <function>maxdb_stmt_execute</function>, the <function>maxdb_fetch</function>
    function must be used to fetch the data prior to preforming any additional queries.
