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);
}
}
