SQL連接而無需多行

Question

我有三個表，如數據，飽和度，值，其中：

CREATE TABLE DATA(
    data_id INT AUTO_INCREMENT, 
    PRIMARY KEY(data_id) 
); 

CREATE TABLE VALUE(
    value_id INT AUTO_INCREMENT, 
    data_id INT, 
    sample INT, 
    channel_1 DOUBLE, 
    channel_2 DOUBLE, 
    channel_3 DOUBLE, 
    PRIMARY KEY (value_id), 
    FOREIGN KEY(data_id) REFERENCES DATA(data_id) 
); 

CREATE TABLE SATURATION(
    saturation_id INT AUTO_INCREMENT, 
    data_id INT, 
    sample INT, 
    channel_1 INT CHECK (channel_1 >= 0 AND channel_1 <= 1), 
    channel_2 INT CHECK (channel_2 >= 0 AND channel_2 <= 1), 
    channel_3 INT CHECK (channel_3 >= 0 AND channel_2 <= 3), 
    PRIMARY KEY (saturation_id), 
    FOREIGN KEY(data_id) REFERENCES DATA(data_id) 
); 

我已經查詢關鍵詞，比如：

SELECT s.sample AS 'S Sample', s.channel_1 AS '#Ch_1 S', s.channel_2 AS '#Ch_2 ES', s.channel_3 AS '#Ch_3 ES', 
    v.sample AS 'V Sample', v.channel_1 AS '#Ch_1 V', v.channel_2 AS '#Ch_2 V', v.channel_3 AS '#Ch_3 V' 
FROM VALUE v 
    LEFT OUTER JOIN SATURATION s 
    ON v.data_id = s.data_id 
    WHERE s.sample = v.sample AND s.data_id = 1; 

結果是好的，如果數量樣本在一個系列中是相等的。但我想要這樣的事情：

 
----------- 
| ES Sample | #Ch_1 ES | #Ch_2 ES | #Ch_3 ES | EV Sample | #Ch_1 EV | #Ch_2 EV | #Ch_3 EV | 
----------- 
| 1 | 1 | 0 | 1 | 1 | 114.5 | 10.2 | 114.5 | 
----------- 
| 2 | 0 | 0 | 1 | 2 | 114.5 | 10.2 | 114.5 | 
----------- 
| 3 | 0 | 0 | 1 | 3 | 114.5 | 10.2 | 114.5 | 
----------- 
| 4 | 1 | 0 | 1 | 4 | 114.5 | 10.2 | 114.5 | 
----------- 
| null | null | null | null | 5 | 114.5 | 10.2 | 114.5 | 
----------- 

如何做到這一點？通常沒有子句's.sample = v.sample'我得到this。我不想在一個表中存儲飽和度和價值，但我猜這是非常簡單和愚蠢的解決方案。

UPDATE：

下面是其產生result因爲我想（如果我比飽和度在同一系列中有多個值）的查詢：

SELECT v.data_id AS 'V ID', s.data_id AS 'S ID', s.sample AS 'S Sample', s.channel_1 AS '#Ch_1 S', s.channel_2 AS '#Ch_2 S', s.channel_3 AS '#Ch_3 S', 
    v.sample AS 'V Sample', v.channel_1 AS '#Ch_1 V', v.channel_2 AS '#Ch_2 V', v.channel_3 AS '#Ch_3 V' 
FROM SATURATION s RIGHT JOIN VALUE v ON v.sample = s.sample 
WHERE (v.data_id = 1 OR s.data_id IS NULL) AND (s.data_id = 1 OR s.data_id IS NULL); 

Answer 1

我將創建數據之間的示例表價值和飽和度。因此，數據會有許多樣品，每個將具有零個或一個值和零個或一個飽和記錄

然後從該試樣臺驅動查詢，左側的接合部，以價值和飽和度。

讓我知道這是沒有意義的，我會盡量澄清，但希望你明白我的意思。
