Question

I use a SQLite Database and a Java GUI. The information entered on the GUI will be added to a table in the database. This table contains an autoincrement. On the same time I want to display the information on the GUI and change it later.

creating the database:

stat.executeUpdate("create table t1(ROWID INTEGER PRIMARY KEY AUTOINCREMENT, Value);";

adding values to the database:

Statement stat = con.createStatement();
String sql = "insert into t1 values ($next_id,'"+value+');";
stat.executeUpdate(sql);

How can I save the ID in my program so that it will be the same as in the database and I have easy access to my database?

Edit:
I tried the solution mentioned in the comments and run into a NYI exception …

String sql = "insert into t1 values($next_id,'"+value+"');";
PreparedStatement stmt = con.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
ResultSet res = stmt.getGeneratedKeys();
while (res.next()){
     int id = res.getInt(1);
     System.out.println(id);
}
con.commit();

tried also the solution of Russel and got another exception (“not implemented by SQLite JDBC driver”):

String sql = "insert into t1 values($next_id,'"+value+"');";
Statement stat = con.createStatement();
stat.executeUpdate(sql);
stat.executeUpdate("SELECT LAST_INSERT_ROWID() from t1;", Statement.RETURN_GENERATED_KEYS);
ResultSet res = stat.getGeneratedKeys();
while (res.next()){
    int id = res.getInt(1);
    System.out.println(id);
}

What did I wrong?

Answer 1

What about just calling SELECT LAST_INSERT_ID()? This returns the last auto-increment value generated for your connection (not affected by other clients’ actions).

Alternately, looking at the Javadoc, it seems you should be able to do this with an ordinary Statement:

stat.executeUpdate(sql, Statement.RETURN_GENERATED_KEYS);
ResultSet keys = stat.getGeneratedKeys();
