檢查2個sql列並在1列中顯示結果

Question

ok ..我有2個表格......除了列名之外，它們完全一樣，因爲它們處理2個不同的「公司」，儘管...我想要的數據是在具有相同名稱的列中。很多我想要做的事情...是如果tableA.Col2> 0或tableB.Col2> 0，則爲1 .. else 0 ..他們也需要是獨特的...我可以讓他們作爲單獨的表...但我不能讓他們在一起..我需要他們在1列，因爲它是如何被髮送到C3代碼頁，以及它如何讀取... ...結構已經被預先設置了......並且在這個存儲過程中還有大約5個其他的語句正在執行，就像這樣（我也不是那個設置它的人）。所以，如果f這是可能的..我知道請..我也會粘貼我的確切代碼，如果你想看到現實生活中的代碼..我只是試圖簡化它，使其更容易理解。

DECLARE @id INT; 
DECLARE @invest nvarchar(50); 
SET @id = '7633'; 
SET @invest = ''; 


SELECT 'a' + CONVERT(nvarchar, orderfindings.risk_rating) AS cat, COUNT(DISTINCT orderfindings.prnt_id) AS stat 
     FROM orderheader, orderaudits, orderfindings 
     WHERE orderheader.id = orderaudits.orderheader_id AND orderaudits.ID = orderfindings.prnt_id 
     AND orderheader.id = @id AND orderfindings.risk_rating > 0 AND orderaudits.Investor_Name LIKE '%' + @invest + '%' 
     GROUP BY orderfindings.risk_rating 
UNION ALL 
SELECT 'a' + CONVERT(nvarchar, orderagencies.risk_rating) AS cat, COUNT(DISTINCT orderagencies.prnt_id) AS stat 
     FROM orderheader, orderaudits, orderagencies 
     WHERE orderheader.id = orderaudits.orderheader_id AND orderaudits.ID = orderagencies.prnt_id 
     AND orderheader.id = @id AND orderagencies.risk_rating > 0 AND orderaudits.Investor_Name LIKE '%' + @invest + '%' 
     GROUP BY orderagencies.risk_rating

/* 
Results from 1st statement 
cat | stat 
----------- 
a1 | 4 
----------- 
a2 | 5 
----------- 

Results from 2nd statement 
cat | stat 
----------- 
a1 | 3 
----------- 
a2 | 2

I pretty much want 

Results from new awesome statement 
cat | stat 
----------- 
a1 | 5 
----------- 
a2 | 5

I think those are the numbers that would be accurate 
Simple version--- if tableA.Col2 is > 0 or tableB.Col2 is > 0 then 1 else 0 
    |Table A    |    Table B     | result of query 
    | col_1  col2  |  col_1    col2   | 
    -------------------------------------------------------------------- 
1 | 1   5  |  1     3   |   1 
2 | 1   45  |  1     0   |   1 
3 | 1   0  |  1     0   |   0 
4 | 1   0  |  1     3   |   1 

so a1 would be 3...4 records in the tables..but only 3 of them matter because row 3 has 0 
whatevers in col 2 for both tables..there might be 100 records that have 1 for col 1..there 
might only be 1 

我希望這會更有意義......這是有點兒奇怪的任務

試試這個：

DECLARE @id INT; 
DECLARE @invest nvarchar(50); 
SET @id = '7633'; 
SET @invest = ''; 


SELECT Findings.cat [cat], 
     CASE WHEN Findings.stat > 0 OR Agencies.stat > 0 THEN 1 ELSE 0 END [stat] 

FROM (SELECT 'a' + CONVERT(nvarchar, orderfindings.risk_rating) AS cat, COUNT(DISTINCT orderfindings.prnt_id) AS stat 
     FROM orderheader, orderaudits, orderfindings 
     WHERE orderheader.id = orderaudits.orderheader_id AND orderaudits.ID = orderfindings.prnt_id 
     AND orderheader.id = @id AND orderfindings.risk_rating > 0 AND orderaudits.Investor_Name LIKE '%' + @invest + '%' 
     GROUP BY orderfindings.risk_rating) Findings 
INNER JOIN (SELECT 'a' + CONVERT(nvarchar, orderagencies.risk_rating) AS cat, COUNT(DISTINCT orderagencies.prnt_id) AS stat 
     FROM orderheader, orderaudits, orderagencies 
     WHERE orderheader.id = orderaudits.orderheader_id AND orderaudits.ID = orderagencies.prnt_id 
     AND orderheader.id = @id AND orderagencies.risk_rating > 0 AND orderaudits.Investor_Name LIKE '%' + @invest + '%' 
     GROUP BY orderagencies.risk_rating) Agencies 

ON Findings.cat = Agencies.cat

您可以使用子查詢的另一個層面，包括他們在彙總結果 喜歡從這裏你的榜樣。

Select cat , SUM(stat) as stat 
FROM 
(
    YOUR FIRST QUERY 
    UNION ALL 
    YOUR SECOND SECOND QUERY 
) AS subquery 
GROUP BY cat
