Union All 在存储过程中不起作用

Question

ALTER PROCEDURE [dbo].[MyStoredProcedure1]
 @YearToGet int

Group By SDESCR, DYYYY, Division
Having (DYYYY = @YearToGet)  
Order By Division, SDESCR, DYYYY 

union all

我得到的错误是

消息 156，级别 15，状态 1，程序 MyStoredProcedure1，第 36 行不正确 关键字“union”附近的语法。

但我的目标是用户输入一年，例如 2009 年，我的第一个查询将获取 2009 年到昨天 2009 年 12 月 23 日同一日期的所有销售额，而第二个查询将获取 2009 年的总数截至 2009 年 12 月 31 日。

我希望列并排而不是在一列中

Answer 1

如果您想并排显示数据，那么您不想使用 UNION。相反，您可以使用派生表或 CTE，然后加入 SDESC、DYYYY、Division 上的 2 个查询。查看您的查询，唯一（明显）的区别是一个在 Booked 列上包含 where 子句。我们可以将这个 where 子句标准移动到 sum 聚合中，这应该允许我们一次通过表获得我们需要的所有数据。像这样的：

ALTER PROCEDURE [dbo].[MyStoredProcedure1]
 @YearToGet int
AS
SET NOCOUNT ON

Declare @Booked Int
Set @Booked = CONVERT(int,DateAdd(year, @YearToGet - Year(getdate()),                   
                DateAdd(day, DateDiff(day, 1, getdate()), 0) ) )

Select Division, 
       SDESCR,        
       DYYYY, 
       Sum(Case When Booked <= @Booked Then APRICE End) ASofSales, 
       SUM(APRICE) AS YESales, 

       Sum(Case When Booked <= @Booked Then PARTY End) AS ASofPAX,        
       SUM(PARTY) AS YEPAX, 

       Sum(Case When Booked <= @Booked Then NetAmount End) ASofNetSales,        
       SUM(NetAmount) AS YENetSales,

       Sum(Case When Booked <= @Booked Then InsAmount End) ASofInsSales,        
       SUM(InsAmount)  AS YEInsSales, 

       Sum(Case When Booked <= @Booked Then CancelRevenue End) ASofCXSales,        
       SUM(CancelRevenue) AS YECXSales, 

       Sum(Case When Booked <= @Booked Then OtherAmount End) ASofOtherSales,        
       SUM(OtherAmount) AS YEOtherSales,

       Sum(Case When Booked <= @Booked Then CXVALUE End) ASofCXValue,
       SUM(CXVALUE) AS YECXValue
From   dbo.B101BookingsDetails 
Where  DYYYY = @YearToGet
Group By SDESCR, DYYYY, Division
Order By Division, SDESCR, DYYYY 

我鼓励您尝试此程序。我认为它会返回您正在寻找的数据。

已编辑以将小于或等于预订条件。

Answer 2

删除union all 之前的第一个order by。为了理智起见，请保持列名相同。第二个order by 适用于所有行。

顺便说一句，你想要的更接近这个。没有测试，但根据您的描述，这应该很接近。

Answer 3

这里的问题不是 UNION ALL 或者列别名的名称不同。问题在于 UNION ALL 行上方的 ORDER BY 行。如果您删除该行，您的查询将运行。这不会像您想要的那样并排列出数据，但它会允许查询运行。

Answer 4

UNION 的要求包括数据类型相似，每个SELECT 包含相同数量的列，并且这些列在两个SELECTs 中以相同的顺序出现。

编辑：在评论中回答您的问题：如果您想让列并排显示，您必须在两个 SELECT 中放置填充列。

Select Division, SDESCR, DYYYY, 
Sum(APRICE) ASofSales, 
'' AS YESales,
Sum(PARTY) AS ASofPAX,  
'' AS YEPAX

... 以此类推，SELECTS 中的列相同，SELECT 或另一个中的某些列为空。

另一个编辑： 两个 SELECTS 中的列名（或别名）不必相同，但使用不同的别名将帮助您区分哪一列。在聚合字段 (SU​​M) 上，如果您不提供别名，那么弄清楚该列代表什么可能会很棘手。如果您像在 SQL 中所做的那样对列进行别名，并交错空字符串列，我想您会得到您想要的结果。
