mysql - 向 SQL 表中插入测试数据

Question

我正在尝试将一些测试数据插入到 MySQL 数据库中，该数据库混合了引用 ID 和变量值。我的陈述被 MySQL 拒绝了，它是通用的(显然几乎没有值(value))“xxx 附近的语法错误”错误是:

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'            , ''
    )

给出:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''2914' AS PostCode, '' AS CitySuburbName UNION ALL SELECT TimeSlotId FROM Time' at line 4

预计这会插入 22 条记录，其中每条记录的单个 TimeSlotId 来自现有记录，我试图避免对其生成的 ID 进行硬编码。

1. 首先，我哪里出错了？
2. 有没有更好的方法？
3. 这是否可以推断为每个子 SELECT 插入多条记录，DayCode 在周一、周二...周六变化？

要使您当前的代码正常工作，请将其更改为

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'

你可以这样改写

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, '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
