在Apache Derby数据库中插入时获取自动生成的id。

Question

或者有没有办法在另一个表中自动生成外键，即规范化表？

    createConnection();
            stmt = conn.createStatement();
            stmt.execute("insert into PRODUCTS(PRODUCTNAME, PURCHASEPRICE, RETAILPRICE, QUANTITY) values ( '"+product.getProductName()+"',"+product.getPurchasePrice()+","+product.getRetailPrice()+","+product.getQuantity()+")");
            stmt.close();
            shutdown();
