使Pivot Columns动态化

我有以下查询返回一个每个应用程序总错误的数据透视表。但问题是我需要手动指定表列。我想设置@StartDate和@EndDate，查询会自动将列构建为Date + 1

这是查询

set transaction isolation level read uncommitted;

WITH BaseQuery AS (
SELECT 
CASE [Application]  WHEN 'EM_ws.XYZ.com' THEN 'XYZ'
                    WHEN 'XYZ'          THEN 'XWZ'
                    WHEN 'EM_WDE.api'           THEN 'WDE'
                    WHEN 'EM_MMCS'          THEN 'MMCS'
                    ELSE 'UnknownBounce' END AS Application,
CAST ([Log_Time] AS date) AS Date,
COUNT([Message]) AS NBRMSG
FROM
    [GLOBAL_LOG].[dbo].[YSHD_Application_Log] WITH (NOLOCK)
WHERE
      [Log_Time] BETWEEN '2016-09-20 00:00:00' AND '2016-09-22 23:59:00'
      AND
      ([Message] LIKE 'E_%' OR [Message] LIKE '(500) - 1 - Internal Server Error' OR [Message] LIKE ' - {"result":"error","message":"Internal Error","code":600}')    
      AND
    1=1
GROUP BY [Application],[Log_Time]
)
SELECT * FROM BaseQuery
PIVOT (SUM(NBRMSG) FOR Date IN ([2016-09-20],[2016-09-21],[2016-09-22])
) AS PVT

经过一些研究，我尝试了以下但是收到了错误信息

  

＆＃34; VALUE＆＃34;不是有效的函数，属性或字段。

set transaction isolation level read uncommitted;

我更新了查询，现在它给出了以下错误..

根据Sean的推荐，这是一个重新创建原始表的DDL：

这个片段你不需要将字符串转换为XML并返回字符串。刚

SELECT  @cols = STUFF(
               (SELECT DISTINCT ',' + QUOTENAME(wd.WDate) 
                FROM #t wd
                FOR XML PATH('')) 
              ,1,1,'')

编辑

在脚本的第二部分使用sp_executesql，它允许更清晰的代码，参见示例

DECLARE  @query  AS NVARCHAR(MAX),
        @StartDate DATE,
        @EndDate DATE;

SET     @StartDate='2016-09-20';
SET     @EndDate='2016-09-30';

SET @query = 'SELECT 1 WHERE getdate() BETWEEN @p1 AND @p2';

DECLARE @paramDefinition nvarchar(max) = N'@p1 DATE, @p2 DATE';

EXEC sp_executesql @query, @paramDefinition, @p1=@StartDate, @p2=@EndDate;

或者在字面上将值插入查询

DECLARE  @query  AS NVARCHAR(MAX),
        @StartDate DATE,
        @EndDate DATE;

SET     @StartDate='2016-09-20';
SET     @EndDate='2016-09-30';
SET @query = 'SELECT 1 WHERE getdate() BETWEEN ''' + cast(@StartDate as varchar(20)) +''' AND ''' + cast(@EndDate as varchar(20)) + ''''
SELECT @query;  
-- SELECT 1 WHERE getdate() BETWEEN '2016-09-20' AND '2016-09-30' 
EXEC (@query);
