I found a very strange error/behavior in a PreparedStatement  for a
simple SQL Update over a VARCHAR field.
The code is like:

    Statement stmt = con.createStatement();
    PreparedStatement pstIns = con.prepareStatement("update userid.t set
calle = ? ");
    ResultSet rs = stmt.executeQuery( "select calle from userid.t2" );
    while ( rs.next() ) {
                pstIns.clearParameters();
                String x = rs.getString("CALLE");
                pstIns.setString(1, x );
                int nrows = pstIns.executeUpdate();
                System.out.println( "Filas afectadas "+ nrows );
     }


When the parameter fill the full-length of  receiving field and has any
non common character, the update throw a exception like:

java.sql.SQLException: ERROR:  value too long for type character varying(30)

This field/value produce the Exception:   CALLE=[ENFERMERA CLEMON. B§
ALTO ALBR]

If this field is changed to:                        CALLE=[ENFERMERA
CLEMON. B# ALTO ALBR]
then  the update is performed without
any problem.

Although the first value can be Inserted  with a prepared statement
without problems.

A have no explanation to this case , and any help will be appreciated.

Dario Fassi.
