如何在 SELECT/INTO 語句中使用 OUTPUT 子句

Question

我有以下查詢

SELECT 'Luke' AS [Jedi_names], 'Skywalker' AS [Jedi_surname]
INTO #Jedi

CREATE臨時表#Jedi並INSERT其中的數據。

我想使用OUTPUT來顯示我保存在表中的數據，但我無法理解如何使用OUTPUT子句而不收到錯誤消息

“'輸出'附近的語法不正確。”

在INSERT INTO查詢中，我會寫以下內容

INSERT INTO #Jedi([Jedi_names],[Jedi_surname])
OUTPUT INSERTED.*
SELECT 'Luke' AS [Jedi_names], 'Skywalker' AS [Jedi_surname]

但是如果表已經創建，這只是INSERT行..

是否可以在第一個查詢中使用OUTPUT子句？

Answer 1

不能在select語句中使用output子句。 它僅適用於insert 、 update 、 delete和merge 。

另一種選擇是分兩部分進行：首先，創建沒有記錄的臨時表：

SELECT 'Luke' AS [Jedi_names], 'Skywalker' AS [Jedi_surname]
INTO #Jedi 
WHERE 1=0

然后，使用insert...output...select將記錄插入到臨時表中：

INSERT INTO #Jedi
OUTPUT INSERTED.*
SELECT 'Luke' AS [Jedi_names], 'Skywalker' AS [Jedi_surname]

或者簡單地使用select into然后select ：

SELECT 'Luke' AS [Jedi_names], 'Skywalker' AS [Jedi_surname]
INTO #Jedi;

SELECT  [Jedi_names], [Jedi_surname]
FROM #Jedi;

Answer 2

請使用如下

CREATE TABLE #Jedi([Jedi_names] VARCHAR(20),[Jedi_surname] VARCHAR(20))

INSERT INTO #Jedi([Jedi_names],[Jedi_surname])
OUTPUT INSERTED.*
SELECT * FROM 
(
    SELECT 'Luke' AS [Jedi_names], 'Skywalker' AS [Jedi_surname]
)K

輸出

Jedi_names  Jedi_surname
Luke    Skywalker

Answer 3

這是您所追求的語法：

CREATE TABLE #Jedi ([Jedi_forename] varchar(50),
                    [Jedi_surname] varchar(50));

INSERT INTO #Jedi ([Jedi_forename],[Jedi_surname])
OUTPUT Inserted.*
SELECT 'Luke' AS [Jedi_names], 'Skywalker' AS [Jedi_surname]

DROP TABLE #Jedi;

不能在同一個語句中使用OUTPUT和INTO 。

Answer 4

select into將避免日志記錄。 當您使用insert into它就違背了目的。
