MySQL自連接以獲取有序的父子記錄

Question

我有一個具有以下結構的表：

+-----------+--------------+-----------+----------+
| member_id | household_id | firstName | lastName |
+-----------+--------------+-----------+----------+
| 14122     | 0            | Cynthia   | Bookout  |
+-----------+--------------+-----------+----------+
| 14123     | 0            | Kim       | Caves    |
+-----------+--------------+-----------+----------+
| 14124     | 14122        | Marvin    | Bookout  |
+-----------+--------------+-----------+----------+
| 14125     | 13974        | Stacey    | Webb     |
+-----------+--------------+-----------+----------+
| 14126     | 13974        | Nathan    | Webb     |
+-----------+--------------+-----------+----------+
| 14127     | 13974        | Adam      | Webb     |
+-----------+--------------+-----------+----------+
| 14128     | 13974        | Thomas    | Webb     |
+-----------+--------------+-----------+----------+
| 14129     | 0            | Missy     | Hammock  |
+-----------+--------------+-----------+----------+
| 14130     | 0            | Stephanie | Lewis    |
+-----------+--------------+-----------+----------+
| 14131     | 0            | Kelly     | Hutto    |
+-----------+--------------+-----------+----------+
| 14132     | 14130        | James     | Lewis    |
+-----------+--------------+-----------+----------+
| 14133     | 0            | Cindy     | Barnwell |
+-----------+--------------+-----------+----------+
| 14134     | 13828        | NATALIE   | MCMILLAN |
+-----------+--------------+-----------+----------+
| 14135     | 13828        | Steven    | Adams    |
+-----------+--------------+-----------+----------+
| 14136     | 0            | Katherine | Gaskins  |
+-----------+--------------+-----------+----------+

member_id和household_id對某些記錄的父子關系。 例如，記錄member_id 14124是孩子member_id 14122（即其household_id是member_id其父的）。

該表實際上包含數以千計的無序記錄。 我想顯示它們，以便父項后跟其子記錄，然后出現下一個父項及其子記錄，依此類推。 結果也需要按member_id排序。

我試過這個：

SELECT * FROM members WHERE household_id IN (SELECT member_id FROM members WHERE household_id = 0) OR household_id = 0
ORDER BY member_id

但我沒有得到想要的結果。 使用 PHP 以編程方式執行此操作花費的時間太長，因為我必須多次迭代每條記錄。

這是我想要的結果：

+-----------+--------------+--------------+----------+
| member_id | household_id | firstName    | lastName |
+-----------+--------------+--------------+----------+
| 14122     | 0            | Cynthia      | Bookout  |
+-----------+--------------+--------------+----------+
| 14124     | 14122        | Marvin Keith | Bookout  |
+-----------+--------------+--------------+----------+
| 14123     | 0            | Kim          | Caves    |
+-----------+--------------+--------------+----------+
| 14125     | 13974        | Stacey       | Webb     |
+-----------+--------------+--------------+----------+
| 14126     | 13974        | Nathan       | Webb     |
+-----------+--------------+--------------+----------+
| 14127     | 13974        | Adam         | Webb     |
+-----------+--------------+--------------+----------+
| 14128     | 13974        | Thomas       | Webb     |
+-----------+--------------+--------------+----------+
| 14129     | 0            | Missy        | Hammock  |
+-----------+--------------+--------------+----------+
| 14130     | 0            | Stephanie    | Lewis    |
+-----------+--------------+--------------+----------+
| 14132     | 14130        | James        | Lewis    |
+-----------+--------------+--------------+----------+
| 14131     | 0            | Kelly        | Hutto    |
+-----------+--------------+--------------+----------+
| 14133     | 0            | Cindy        | Barnwell |
+-----------+--------------+--------------+----------+
| 14134     | 13828        | NATALIE      | MCMILLAN |
+-----------+--------------+--------------+----------+
| 14135     | 13828        | Steven       | Adams    |
+-----------+--------------+--------------+----------+
| 14136     | 0            | Katherine    | Gaskins  |
+-----------+--------------+--------------+----------+

Answer 1

嘗試以下查詢：

SELECT a.member_id as parent_id,
       a.firstName as parent_firstName,
       a.lastName as parent_lastName,
       b.member_id as child_id,
       b.firstName as child_firstName,
       b.lastName as child_lastName
FROM members a inner join members b on a.member_id = b.household_id
ORDER BY a.member_id
