如何針對一系列值對運行查詢並將結果存儲在臨時表中？

Question

假設我有值的數組：

（A1，A1，A2，A2，A3，A3，A4，A4 .....，一個，一個）

我應該怎樣和自動化對運行（A1，A1 ...，AN，一個）的下面TSQL查詢對

SELECT COUNT (1) 
FROM food 
WHERE calories = Ai AND ingredient = ai --i = {1..n} 

這樣每個計數由（艾，AI）得到{I = 1..N}將存儲在臨時表中？

感謝

Answer 1

插入您的數組中的值到一個臨時表（我將使用同一個用於後來的結果）：

create table #pairs (
    calories varchar(50), 
    ingredient varchar(50), 
    count  int 
) 

然後，我們可以得到我們的結果一步到位：

UPDATE p 
SET count = x.count 
FROM #pairs p inner join 
    ( SELECT f.calories, f.ingredient, COUNT(*) as count 
     FROM food f inner join 
      #pairs p ON f.calories = p.calories and f.ingredient = p.ingredient 
     GROUP BY f.calories, f.ingredient 
    ) x ON p.calories = x.calories and p.ingredient = x.ingredient 


select * from #pairs

你可以用SQL DYNAMIX，像這樣做：

declare @count int, @limit int 
select @count = 0, @limit = 5 -- limit is n 

declare @sqlcmd varchar(300) 

-- table 
create table #result (
combination varchar(10), 
total int 
) 

while @count < @limit 
begin 
    select @sqlcmd = 'insert into #results select distinct "(" + ingredient + "," + calories + ")", count(*) from food where calories = A' + convert(varchar, @count) + ' and ingredient = a' + convert(varchar, @count) 

    exec(@sqlcmd) 

    select @count = @count + 1 
end
