如何获取 SQL 更新的主键？

Question

如果找到“searchedWord”，我将更新表格。如果找到它，我想知道我刚刚更新的记录的主键是什么。我该怎么做？下面是我的代码。附带说明一下，如果找不到“searchedWord”，我将其插入并使用 scope_identity() 来获取它。我的问题是如何对更新做同样的事情？我想我可以先做一个 select 语句，但这是一个额外的查询。

BEGIN TRAN    
    UPDATE COBC_searchedWord 
    SET searchCount=searchCount+1, 
        resultsReturned=#resultsReturned#, 
        lastSearched=getDate() 
    WHERE searchedWord='#searchedWord#';

    IF @@ROWCOUNT = 0
    BEGIN
        INSERT INTO COBC_searchedWord
            ([searchedWord] ,[searchCount] ,[resultsReturned] ,[lastSearched])
        VALUES
            ('#searchedWord#',1,'#resultsReturned#',getDate())
        SELECT scope_identity() AS searchedWordID
    END
COMMIT TRAN

更新：这就是我最终的结果，它似乎有效。感谢您的意见。

DECLARE @tmpTable TABLE (ID int);  
UPDATE COBC_searchedWord
SET searchCount=searchCount+1, 
    resultsReturned=#resultsReturned#, 
    lastSearched=getDate()  
OUTPUT inserted.searchedWordID into @tmpTable          
WHERE searchedWord='#searchedWord#';          

IF @@ROWCOUNT = 0  
BEGIN  
    INSERT INTO COBC_searchedWord  
        ([searchedWord])         
        OUTPUT inserted.searchedWordID into @tmpTable  
    VALUES  
        ('#searchedWord#');  
END  
SELECT ID from @tmpTable;

Answer 1

您应该使用 OUTPUT 子句。在线书籍将解释如何。

Answer 2

试试这个，如果你正在更新你的记录，并且在表中找到了搜索词，然后从表中选择 searchedWordID

BEGIN TRAN    
    UPDATE COBC_searchedWord 
    SET searchCount=searchCount+1, 
        resultsReturned=#resultsReturned#, 
        lastSearched=getDate() 
    WHERE searchedWord='#searchedWord#';

    IF @@ROWCOUNT = 0
    BEGIN
        INSERT INTO COBC_searchedWord
            ([searchedWord] ,[searchCount] ,[resultsReturned] ,[lastSearched])
        VALUES
            ('#searchedWord#',1,'#resultsReturned#',getDate())
        SELECT scope_identity() AS searchedWordID
    END
    ELSE
    BEGIN
      SELECT searchedWordID FROM COBC_searchedWord 
      WHERE searchedWord='#searchedWord#';
    END
COMMIT TRAN
