java - 使用通过jtable从mysql获取多个数据

Question

我需要使用 netbeans 中的表从 mysql 获取多个数据

try {
            for (int row = 0; row < rows; row++) {
                String QB = (String) tblHizliFatura.getValueAt(row, 0);
                String miktar = (String) tblHizliFatura.getValueAt(row, 7);

                Class.forName("com.mysql.cj.jdbc.Driver");
                Conn = DriverManager.getConnection(url, user, pass);
                Statement st = Conn.createStatement();
                String sql = SELECT miktar FROM companydb.stokeklefinaltbl where QB = " + QB + " and depo = " + miktar;
                ResultSet rs = st.executeQuery(sql);

                while (rs.next()) {
                    stokMk[row] = rs.getDouble("miktar");
                }
            }
        } catch (Exception ex) {
            System.out.println(ex.getMessage());
        }
for(int i = 0; i < rows; i++){
            System.out.println(Double.toString(stokMk[i]));
        }

但是我无法根据“QB”和“depo”获得“miktar”值，如何根据“QB”和“depo”获得“miktar”值，请您帮帮我。
