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.
