     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. For a list of possible values, see 
     <ulink url="&url.mysql.docs.error;">&url.mysql.docs.error;</ulink>.

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