  <para>
   Retrieves the contents of one cell from a MySQL result set.
  </para>
  <para>
   When working on large result sets, you should consider using one
   of the functions that fetch an entire row (specified below).  As
   these functions return the contents of multiple cells in one
   function call, they're MUCH quicker than
   <function>mysql_result</function>.  Also, note that specifying a
   numeric offset for the field argument is much quicker than
   specifying a fieldname or tablename.fieldname argument.

       The row number from the result that's being retrieved. Row numbers

       The name or offset of the field being retrieved.

      <para>
       It can be the field's offset, the field's name, or the field's table 
       dot field name (tablename.fieldname). If the column name has been
       aliased ('select foo as bar from...'), use the alias instead of the 
       column name. If undefined, the first field is retrieved.
