SQL Server：在「當前」表更新爲「歷史」表時創建一個觸發器

Question

我正在從Oracle 9i數據庫遷移到SQL Server，並試圖解決和翻譯我們必須維護的一個觸發器記錄的歷史。 History表有其自己的ID列，其他所有列與Current表中的相同。

這裏是我的觸發如從ORADB：（在ORADB我們使用的是順序遞增的「歷史」 PK）

CREATE OR REPLACE TRIGGER "RC_CURRENT_T" 
BEFORE INSERT OR UPDATE 
ON RC_CURRENT

    DECLARE var_date VARCHAR2(30 BYTE); 
    BEGIN

     var_date:=TO_CHAR(CURRENT_DATE, 'MM/DD/YYYY HH24:MI:SS');

我試圖跟隨，但得到的錯誤信息

INSERT語句的選擇列表包含的項目少於
插入列表。 SELECT值的數量必須與INSERT 列的數量相匹配。

代碼：

CREATE TRIGGER RC_CURRENT_T 
ON [dbo].[RC_CURRENT] 
FOR UPDATE 
AS 
BEGIN 
    SET NOCOUNT ON; 

    INSERT INTO [dbo].[RC_HISTORY]

    ,[USER_REQUESTTYPE] 
    ,[REC_ENTRY_DATE] 
    ) 
    SELECT * FROM RC_CURRENT 
END 
GO 

我需要保持在歷史表中單獨的ID爲報告的目的。

任何援助非常感謝。

謝謝。

Answer 1

看着舊的觸發器（和錯誤消息）RC_HISTORY有1個額外的字段相比，RC_CURRENT所以你有兩個選項。

1. 如果[REC_ID]是自動遞增標識列，你可以簡單地從列的列表中刪除它插入到

   INSERT INTO [dbo].[RC_HISTORY] 
   ([STATUS_DESCR] 
   ,[REQBY_FULLNAME] 
   ,[REQBY_USERNAME] 
   ... 
   

2. 如果[REC_ID]沒有被設置爲自動增量，那麼你將有以提供一個值，以插入到柱

   SELECT (SELECT MAX([REC_ID])+1 FROM RC_HISTORY), * FROM RC_CURRENT 
   

我建議你嘗試第一個選項，並將列設置爲身份列，如果它尚未，我也建議你也使用命名列而不是*選擇值。
