Subject: [JDBC] SQLState with pg74.1jdbc3.jar

Hi all,
I'm a newbie in JDBC code.

I tried to execute a Statement.executeUpdate() method to insert a row
already present in my Postgresql DB.

With JDBC I receive a SQLException but I would like to have
more informations about the error (something like Duplicate Key
Exception).

I read that SQLException class have the getSQLState() method, but
when I call it, the result is null (the getErrorCode() return always 0).

The same if I try to generate another error (an INSERT command
without specifying all NOT NULL colums of my table).

I use pg74.1jdbc3.jar on a i686 Intel - Suse host.

Here is the code (insertCommand is intentionally a wrong command)

public int execInsert(String insertCommand) {
Statement stateSql;
Connection conn;

conn = <get the Connection>;

try {
stateSql = conn.createStatement();
return(stateSql.executeUpdate(insertCommand));
}
catch (SQLException e) {
System.out.println("SQLException: error code = " +
e.getErrorCode());
System.out.println("SQLException: sqlstate = " +
e.getSQLState());
return(-1);
}
}
