Is there a way to retrieve the autoincrement ID from a prepared statement
Yes. See here. Section 7.1.9. Change your code to:
String sql = "INSERT INTO table (column1, column2) values(?, ?)";stmt = conn.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);stmt.executeUpdate();if(returnLastInsertId) { ResultSet rs = stmt.getGeneratedKeys(); rs.next(); auto_id = rs.getInt(1);}
There's a couple of ways, and it seems different jdbc drivers handles things a bit different, or not at all in some cases(some will only give you autogenerated primary keys, not other columns) but the basic forms are
stmt = conn.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS); Or use this form:
String autogenColumns[] = {"column1","column2"};stmt = conn.prepareStatement(sql, autogenColumns)
Yes, There is a way. I just found this hiding in the java doc.
They way is to pass the AutoGeneratedKeys id as follows
String sql = "INSERT INTO table (column1, column2) values(?, ?)";stmt = conn.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
