如何自動更新運行數據結果的'期間'列存儲過程

Question

這是存儲過程的部分腳本。 我希望能夠自動更新（以下數據結果）的下一個 'P4'（依此類推）列數：

/* 
RESULTS: 
66, 
221, 
0 
*/ 


DECLARE 
@APP_TOTAL INT 
, @DB_TOTAL INT 
, @OS_TOTAL INT 
, @YEAR INT 

SET @APP_TOTAL = (SELECT COUNT(*) 
    FROM [db_eCAM].[dbo].[tbl_SecChecks] 
WHERE LAYER = 'APP' AND [ENABLE] = 1) 
PRINT @APP_TOTAL 

SET @DB_TOTAL = (SELECT COUNT(*) 
    FROM [db_eCAM].[dbo].[tbl_SecChecks] 
WHERE LAYER = 'DB' AND [ENABLE] = 1) 
PRINT @DB_TOTAL 

SET @OS_TOTAL = (SELECT COUNT(*) 
    FROM [db_eCAM].[dbo].[tbl_SecChecks] 
WHERE LAYER = 'OS' AND [ENABLE] = 1) 
PRINT @OS_TOTAL 

SET @YEAR = 2013 

Answer 1

也許是這樣的：

update mytable 
    set p4 = case 
     when description = 'APP_TOTAL' then @APP_TOTAL 
     when description = 'DB_TOTAL' then @DB_TOTAL 
     when description = 'OS' then @OS_TOTAL 
    end 
where description in ('APP_TOTAL', 'DB_TOTAL', 'OS');

要使句號＃動態，您可以使用如下所示的動態SQL：http://www.sqlfiddle.com/#!3/f575c/5
