Question

好吧..我有2个表......它们完全相同，除了其中一个的列名，因为它们处理2个不同的“公司”，尽管...我想要的数据是在具有相同的列中name.pretty很多我想要做的......如果tableA.Col2是＆gt;那么 0或tableB.Col2是> 0然后1 ..否则0 ..他们也需要区别......我可以把它们作为单独的表...但我不能把它们放在一起..我需要它们在1列中因为它如何被发送到C3代码页以及它是如何读取的...结构已经预先设置了......并且在这个存储过程中有大约5个其他正在执行的语句（也是我不是设置的那个）这个）。所以，如果这是可能的..我知道请...我也会粘贴我所拥有的确切代码，如果你想看到真实生活代码..我只是试图简化它，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

I pretty much want

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

我希望这更有意义......这是一项奇怪的任务

Answer 1

您可以使用其他级别的子查询将它们包含在摘要结果中就像你在这里的例子一样。

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

试试这个：

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

检查2个sql列并在1列中显示结果
