將測試數據插入到SQL表中

Question

我試圖將一些測試數據插入到MySQL數據庫中，該數據庫具有參考ID和變量值的混合。我的發言，由MySQL與它拒絕的通用（和公然旁邊毫無價值） 「語法錯誤附近xxx」 的錯誤是：

INSERT INTO TimeSlotWorker (TimeSlotId, WorkerId, PostCode, CitySuburbName) 
SELECT      TimeSlotId, 1  , PostCode, CitySuburbName 
FROM (
       SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 1), '2914' AS PostCode, '' AS CitySuburbName 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 2), '2912'   , '' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 2), '2913'   , '' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 2), '2911'   , '' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Charnwood' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Dunlop' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Florey' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Flynn' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Fraser' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Higgins' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Holt' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Kippax' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Latham' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Macgregor' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Melba' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2615'   , 'Spence' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2614'   , 'Aranda' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 3), '2614'   , 'Cook' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 4), '2617'   , '' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 5), '2602'   , '' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 5), '2612'   , '' 
    UNION ALL SELECT TimeSlotId FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 6), '2609'   , '' 
    ) 

這給：

com.mysql.jdbc.exceptions.jdbc4 .MySQLSyntaxErrorException：您的SQL語法中有錯誤;檢查對應於你的MySQL服務器版本郵編，'AS CitySuburbName UNION ALL SELECT TimeSlotId不時」使用「附近」 2914' 第4行

期待此項插入22條記錄正確的語法手冊每一個單一的TimeSlotId來自一個現有的記錄，我試圖避免硬編碼其生成的ID。

1. 我哪裏錯了，首先？
2. 有沒有更好的方法？
3. 可以通過MON，TUE ... SAT來推斷插入每個子SELECT的多個記錄與DayCode不同嗎？

Answer 1

每個UNION-ed SELECT語句都有相同的語法錯誤，無法解析。孤立地考慮的第一個

SELECT TimeSlotId FROM TimeSlot 
    WHERE (DayCode = 'MON' AND SequenceNbr = 1), 
    '2914' AS PostCode, '' AS CitySuburbName 

這些額外的列名必須是之前的FROM關鍵字：

SELECT TimeSlotId, '2914' AS PostCode, '' AS CitySuburbName 
    FROM TimeSlot 
    WHERE (DayCode = 'MON' AND SequenceNbr = 1), 

另外，整個選擇（SELECT）建設是不必要的相反，你可以插入聯合在一起一起直接SELECT語句：

INSERT INTO Table (ColList) 
    SELECT SameNumberOfColumns FROM OtherTable WHERE . . . 
    UNION ALL 
    SELECT SameNumberOfColumns FROM OtherTable WHERE . . . 

（等）

Answer 2

.1。您的子查詢只有一列TimeslotId，而在主查詢中，您選擇了三個（PostCode和CitySuburbName）。這不是一個真正的語法錯誤，但它是不正確的。語法錯誤是因爲你在做在select語句之後添加那些缺失的字段，而它們應該是它的一部分。

你需要格式化子查詢是這樣的：

  SELECT TimeSlotId, '2914' AS PostCode, '' AS CitySuburbName FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 1) 
UNION ALL SELECT TimeSlotId, '2912', '' FROM TimeSlot WHERE (DayCode = 'MON' AND SequenceNbr = 2) 
UNION ALL ... 

因此，使常數值郵編和字段列表的CitySuburbName一部分。你不能在select語句後粘貼它們。

.2。我認爲這是一個很好的方法。最好的之一。 :)

.3。我不確定你的意思，但聽起來好像你可以將where子句中的DayCode排除在外，因此聯合中的每個查詢都會返回多條記錄。

爲了讓您當前的代碼工作將其更改爲

INSERT INTO TimeSlotWorker (TimeSlotId, WorkerId, PostCode, CitySuburbName) 
SELECT      TimeSlotId, 1  , PostCode, CitySuburbName 
FROM 
(
      SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 1) TimeSlotId, '2914' PostCode, '' CitySuburbName 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 2)   , '2912'   , '' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 2)   , '2913'   , '' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 2)   , '2911'   , '' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2615'   , 'Charnwood' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2615'   , 'Dunlop' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2615'   , 'Florey' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2615'   , 'Flynn' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2615'   , 'Fraser' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2615'   , 'Higgins' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2615'   , 'Holt' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2615'   , 'Kippax' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2615'   , 'Latham' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2615'   , 'Macgregor'

    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3)   , '2614'   , 'Cook' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 4)   , '2617'   , '' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 5)   , '2602'   , '' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 5)   , '2612'   , '' 
    UNION ALL SELECT (SELECT TimeSlotId FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 6)   , '2609'   , ''

你可以把它改寫這樣

INSERT INTO TimeSlotWorker (TimeSlotId, WorkerId, PostCode, CitySuburbName) 
SELECT TimeSlotId, 1, '2914', ''   FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 1 UNION ALL 
SELECT TimeSlotId, 1, '2912', ''   FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 2 UNION ALL 
SELECT TimeSlotId, 1, '2913', ''   FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 2 UNION ALL 
SELECT TimeSlotId, 1, '2911', ''   FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 2 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Charnwood' FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Dunlop' FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Florey' FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Flynn'  FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Fraser' FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Higgins' FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Holt'  FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Kippax' FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Latham' FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Macgregor' FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Melba'  FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2615', 'Spence' FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2614', 'Aranda' FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2614', 'Cook'  FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 3 UNION ALL 
SELECT TimeSlotId, 1, '2617', ''   FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 4 UNION ALL 
SELECT TimeSlotId, 1, '2602', ''   FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 5 UNION ALL 
SELECT TimeSlotId, 1, '2612', ''   FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 5 UNION ALL 
SELECT TimeSlotId, 1, '2609', ''   FROM TimeSlot WHERE DayCode = 'MON' AND SequenceNbr = 6
