C# 可组合DML错误

我有以下可组合的dml，我似乎无法设置它的工作。有人能帮我指出哪里出了问题吗

INSERT INTO order_kit (kit_no, order_id) 
SELECT 
    X.kit_no, 10089 
FROM 
    (
    MERGE INTO kit AS tgt 
    USING
        (SELECT TOP 2 kit_no 
         FROM kit rk, batch rb 
         WHERE rk.study_id = 35 AND 
         rk.batch_id = rb.batch_id AND 
         rb.depot_id = 16 AND 
         rk.treatment = 1 AND 
         rk.status = 1 AND 
         rb.status = 1 AND 
         rb.expiry > CAST(FLOOR(CAST(getdate() AS float)) AS datetime)
         ) AS src ON tgt.kit_no = src.kit_no 
         WHEN MATCHED THEN 
            UPDATE SET status = 6 OUTPUT $action as action, kit_no) AS X

列名“kit_no”无效。（*在最后一行）

---

当FROM子句包含嵌套的INSERT、UPDATE、DELETE或MERGE语句时，INSERT语句的目标表“order_kit”不能位于（主键、外键）关系的任一侧。找到引用约束“FK\U order\U kit\U order”。

很难猜测您何时没有提供表定义，但我猜第一个错误是因为您有一个不合格的

kit\U no

。成功

SELECT TOP 2 rk.kit_no

看看会发生什么

另外，我认为第二个错误是显而易见的。

工具包。\u no

。成功

SELECT TOP 2 rk.kit_no

另外，我认为第二个错误很明显。

您必须在输出子句中限定

kit\u no

OUTPUT $action as action, src.kit_no

我真的不明白你怎么会同时犯这两个错误。SQLServer通常一次只对一个查询抱怨一件事

您可以通过创建一个表变量来解决第二个问题，将

输出改为

，并使用该表变量作为源，将行插入到

order\u kit

update top (2) rk
set [status] = 6
output inserted.kit_no, 10089 into order_kit(kit_no, order_id)
from kit as rk
  inner join batch as rb
    on rk.batch_id = rb.batch_id 
where
  ...

更新

您可以使用update而不是merge来简化这一点，并将输出直接输入到

order\u kit

update top (2) rk
set [status] = 6
output inserted.kit_no, 10089 into order_kit(kit_no, order_id)
from kit as rk
  inner join batch as rb
    on rk.batch_id = rb.batch_id 
where
  ...

我通过使用

SELECT 
    X.kit_no, 10089 
FROM 
    (
    MERGE INTO kit AS tgt 
    USING

         WHERE rk.study_id = 35 AND

         rb.depot_id = 16 AND 
         rk.treatment = 1 AND 
         rk.status = 1 AND 
         rb.status = 1 AND 
         rb.expiry > CAST(FLOOR(CAST(getdate() AS float)) AS datetime)
         ) AS src ON tgt.kit_no = src.kit_no
