    <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.
