       Can be the field's offset, the field's name or the field's table dot
       field's name (tablename.fieldname). If the column name has been
       aliased ('select foo as bar from...'), it uses the alias instead of
       the column name.

        Specifying a numeric offset for the <parameter>field</parameter>

        <literal>fieldname</literal> or 
        <literal>tablename.fieldname</literal> argument.

    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>mssql_result</function>.
