執行將查詢作爲參數的存儲過程

Question

如何爲每個ProductId執行sp_1並獲取結果集？

EXEC sp_1 (SELECT ID FROM Products) 

Answer 1

試試這種方法。看起來沒有直接的查詢。 execute sp for each row

或者試試這個，如果需要的話做一些小的改動。用臨時表來獲取sp值。如果需要，請在sp內使用以下內容。

begin 
declare @ID int 
declare @temp table (col1 int) 
declare cur cursor for select distinct ID from products 
open cur 
fetch next from cur into @ID 
truncate table @temp 
while(@@FETCH_STATUS=0) 
begin 
insert into @temp (<'cols/output from procedure'>) exec (@ID) 
end 
select * from @temp 
end 

Answer 2

我將存儲的ID在一個臨時表和使用循環（避免CURSORS！）

 
DECLARE @prodid INT 
SELECT prodid, 0 as Processed INTO #prod_ids FROM Products 

WHILE EXISTS (SELECT prodid FROM #prod_ids WHERE Processed = 0) 
BEGIN 
    SELECT TOP 1 @prodid = prodid FROM #prod_ids WHERE Processed = 0 
    EXEC sp_1(@prodid) 
    UPDATE #prod_ids SET Processed = 1 WHERE prodid = @prodid 
END
