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

SELECT * FROM BaseQuery
PIVOT (SUM(NBRMSG) FOR Date IN ([2016-09-20],[2016-09-21],[2016-09-22])

答案 0 :(得分：0)
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);
