合併SQL查詢的結果

Question

我想將此查詢的結果合併到一個列表中的所有數據。 '聯盟'沒有幫助...

有什麼想法嗎？

DECLARE @cnt INT = 0 
DECLARE @SQLQuery AS NVARCHAR(500) 
DECLARE @items AS VARCHAR(500) 
DECLARE @stline AS VARCHAR(500) 



while @cnt < 101 

begin 

set @items = 'LG_0' + convert(nvarchar(3),@cnt) + '_ITEMS' 
set @stline = 'LG_0' + convert(nvarchar(3),@cnt) + '_01_STLINE' 

if (OBJECT_ID (@items) is not null and OBJECT_ID(@stline) is not null) 

set @SQLQuery = 'SELECT 
    ITM1.CODE, itm1.NAME, max (stl.date_) [latest date] , price as [latest price], '+ convert(nvarchar(3),@cnt) + ' as [proje kodu] 

FROM ' + @items + ' ITM1 INNER JOIN ' + @stline + ' STL 
    ON ITM1.LOGICALREF = STL.STOCKREF 
WHERE PRICE > 0 
    AND TRCODE = 1 
    AND CANCELLED = 0 
    AND INVOICEREF > 0 


    group by code, name, stl.DATE_ , price 

    ' 

    exec (@SQLQuery) 



    set @cnt = @cnt +1 


end 

的結果是這樣的：

，但我希望他們所有聯盟-ED ......（對不起，大多是代碼的問題，我要在這裏添加更多的打字）

DECLARE @cnt INT = 0 
DECLARE @SQLQuery AS NVARCHAR(max) 
DECLARE @items AS VARCHAR(500) 
DECLARE @stline AS VARCHAR(500) 

set @SQLQuery ='' 

while @cnt < 101 

begin 

set @items = 'LG_0' + convert(nvarchar(3),@cnt) + '_ITEMS' 
set @stline = 'LG_0' + convert(nvarchar(3),@cnt) + '_01_STLINE' 

if (OBJECT_ID (@items) is not null and OBJECT_ID(@stline) is not null) 

set @SQLQuery = @SQLQuery + 'SELECT 
    ITM1.CODE, itm1.NAME, max (stl.date_) [latest date] , price as [latest price], '+ convert(nvarchar(3),@cnt) + ' as [proje kodu] 

    FROM ' + @items + ' ITM1 INNER JOIN ' + @stline + ' STL 
     ON ITM1.LOGICALREF = STL.STOCKREF 
    WHERE PRICE > 0 
     AND TRCODE = 1 
     AND CANCELLED = 0 
     AND INVOICEREF > 0 
    GROUP BY code, name, stl.DATE_ , price 

    UNION ALL 

    '  
    set @cnt = @cnt +1 
end 

-- SUBSTRING to remove last UNION ALL 
--PRINT len(@SQLQuery) 

set @SQLQuery = left (@SQLQuery , len(@SQLQuery)-18) 


--PRINT len(@SQLQuery) 

-- print @SQLQuery 

-- For debugging purposes 
-- PRINT @SQLQuery 
exec (@SQLQuery)

我不知道爲什麼UNION沒有爲你工作，但下面應該工作：

DECLARE @cnt INT = 0 
    DECLARE @SQLQuery AS NVARCHAR(MAX) = '' 
    DECLARE @items AS VARCHAR(500) 
    DECLARE @stline AS VARCHAR(500) 

    while @cnt < 101 

    begin 

    set @items = 'LG_0' + convert(nvarchar(3),@cnt) + '_ITEMS' 
    set @stline = 'LG_0' + convert(nvarchar(3),@cnt) + '_01_STLINE' 

    if (OBJECT_ID (@items) is not null and OBJECT_ID(@stline) is not null) 

    set @SQLQuery = @SQLQuery + 'SELECT 
     ITM1.CODE, itm1.NAME, max (stl.date_) [latest date] , price as [latest price], '+ convert(nvarchar(3),@cnt) + ' as [proje kodu] 

     FROM ' + @items + ' ITM1 INNER JOIN ' + @stline + ' STL 
      ON ITM1.LOGICALREF = STL.STOCKREF 
     WHERE PRICE > 0 
      AND TRCODE = 1 
      AND CANCELLED = 0 
      AND INVOICEREF > 0 
     GROUP BY code, name, stl.DATE_ , price 

     UNION ALL 
     '  
     set @cnt = @cnt +1 

    end 

    -- SUBSTRING to remove last UNION ALL 
    SELECT @SQLQuery = SUBSTRING(@SQLQuery, 1, LEN(@SQLQuery) - 18) 

    -- For debugging purposes 
    -- PRINT @SQLQuery 
    exec (@SQLQuery) 

我無法測試它，但你可以發表評論的exec，並取消對PRINT看到正在發生什麼樣的查詢。它使調試動態SQL變得容易很多。

這段代碼背後的思想：第一UNION ALL查詢正在建設，根據你的條件。最後刪除最後的UNION ALL，然後可以執行代碼。
