    <para>
     Returns a string containing the SQLSTATE error code for the last error. 
     The error code consists of five characters. <literal>'00000'</literal> means no error.
     The values are specified by ANSI SQL and ODBC.

    <note>
     <para>
      Note that not all MaxDB errors are yet mapped to SQLSTATE's. 
      The value <literal>HY000</literal> (general error) is used for unmapped errors.
