MERGE和條件匹配

Question

我有一個表格類型，我發送作爲我的存儲過程中的變量。

CREATE TYPE OperationKeysTableType AS TABLE 
(
    [KeysId] [int] NOT NULL,     
    [OperationId] [int] NOT NULL,     
    [IsChecked] [bit] NOT NULL 
) 

然後，我想用這個表做一個搜索，如果他們匹配與否，插入或刪除，但只有當它沒有被選中，像這樣：

MERGE INTO dbo.tblOperationKeys AS T 
USING (SELECT VT.KeysId, VT.OperationId as OperationId FROM @ValuesTable AS VT) AS S 
ON T.KeysId = S.KeysId AND T.OperationId = S.OperationId 
WHEN MATCHED AND S.IsChecked = 0 THEN --DELETE 
    DELETE 
WHEN NOT MATCHED THEN--INSERT 
    INSERT (KeysId, OperationId) VALUES (S.KeysId, S.OperationId) 
OUTPUT $action AS ChangesMade, inserted.OperationKeysId AS new_OperationKeysId, deleted.OperationKeysId AS old_OperationKeysId; 

我的問題是， SQL告訴我IsChecked無效。任何想法我做錯了什麼？

Answer 1

您沒有選擇IsChecked。

在生產線：

USING (SELECT VT.KeysId, VT.OperationId as OperationId FROM @ValuesTable AS VT) AS S 

您需要：

USING (SELECT VT.KeysId, VT.OperationId as OperationId, VT.IsChecked as IsChecked FROM @ValuesTable AS VT) AS S
