Question

我试图在使用MS-SQL 2012查询结果的末尾有一个总行，需要一些帮助继承我的查询

SELECT
PropertyValue As Answer,Count(*) As rCount 
FROM 
QuestionerDetail AS Temp
where 
QuestionId = 42 and FormId = 1 
GROUP BY PropertyValue
Union All
SELECT 'Total',sum(rCount) 
FROM 
temp

我在这里做了一些非常错误的事情。

结果应该像

Answer rCount
-------------
 One     10
 Two     25
 Total   35

感谢。

Answer 1

您无法在联盟的其他部分使用别名。

请尝试以下代码：

SELECT
PropertyValue As Answer, Count(*) As rCount 
FROM 
QuestionerDetail AS Temp
where 
QuestionId = 42 and FormId = 1 
GROUP BY PropertyValue
Union All
SELECT 'Total', COUNT(*) 
FROM 
QuestionerDetail 
where 
QuestionId = 42 and FormId = 1

Answer 2

由于您使用的是SQL Server，因此可以使用CTE执行此操作。

;WITH Temp AS
(
SELECT PropertyValue As Answer, Count(*) As rCount 
FROM QuestionerDetail 
WHERE QuestionId = 42 and FormId = 1 
GROUP BY PropertyValue
)

SELECT Answer, rCount
FROM Temp
UNION ALL
SELECT 'Total' as Answer, SUM(rCount) as rCount
FROM Temp

Answer 3

您可以使用以下语法：

WITH Temp AS(
              SELECT
                  PropertyValue As Answer
                  ,Count(*) As rCount 
              FROM QuestionerDetail AS Temp
              where QuestionId = 42 and FormId = 1 
              GROUP BY PropertyValue
             )
SELECT Answer, rCount  FROM Temp
UNION ALL
SELECT 'Total', SUM(rCount)  FROM Temp

我希望它会对你有所帮助!! 祝你好运：）

Answer 4

只需添加WITH ROLLUP：

SELECT
PropertyValue As Answer, Count(*) As rCount 
FROM 
QuestionerDetail AS Temp
GROUP BY PropertyValue WITH ROLLUP

Answer 5

我已经在RAILS中创建了这个连接表，所以我希望在底线总共得到price_value。

这是控制器操作视图代码

def daily_wise_report
        @result = Item.select(:name, :price_value, :item_id). joins(:order_items)
        respond_to do |format|
            format.html
            format.csv { send_data @result.to_csv }
            format.xls
        end

将总行添加到查询结果的末尾
