如何获取 SQL 更新的主键?

How to get Primary Key on SQL Update?

如果找到 "searchedWord",我将更新 table。如果找到,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。另外,如果找不到 "searchedWord",我会插入它并使用 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,但那是一个额外的查询。

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:这就是我最终得到的,它似乎有效。感谢您的输入。

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;

您应该使用 OUTPUT 子句。在线书籍将解释如何。

试试这个,如果你正在更新你的记录,并且那个搜索词 focund 在 table 然后 select 来自 table

的 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
