【问题描述】：
我在 asp.net 2005 和 SQL Server 2008 R2 的类型化数据集中有这个 SQL 查询。 即我在类型化数据集中使用过——“添加查询”——“使用 Sql 语句”并使用了下面的脚本，然后我返回了一个数据表。 （“填写数据表”复选框未选中“）
SELECT DISTINCT
ISNULL(Projects.ProjectID,'0') as
ProjectID,Messages.MessageID, Projects.ProjectName, Customers.CustomerName as
CustomerName, Regions.RegionName,
(select U.firstName + ' ' + U.LastName
from Users U inner join Projects P on P.ProjectManagerId = U.UserID inner join
Messages M on M.ProjectId = P.ProjectID
where M.MessageID = Messages.MessageID) as ProjectManagerName,
dbo.phases.TagName as Phase,
(select U.firstName + ' ' + U.LastName
from Users U inner join Messages M on M.CreatedBy = U.UserID Where M.MessageID =
Messages.MessageID) as CreatedBy,
Messages.DateCreated as EmailCreatedDate,
Messages.MessageSubject as MessageSubject,
Users.Email as [From],
**(stuff((select ','+U.EMAIL
FROM USERS U INNER JOIN Recipients R ON U.USERID = R.USERID INNER JOIN MESSAGES M
ON R.MESSAGEID = M.MESSAGEID
WHERE m.MessageID=Messages.MessageID AND R.RecipientTypeID=1
for xml path(''), type).value('.', 'nvarchar(max)'), 1, 1, '')) as [TO],**
**(stuff((select ','+U.EMAIL
FROM USERS U INNER JOIN Recipients R ON U.USERID = R.USERID INNER JOIN
MESSAGES M ON R.MESSAGEID = M.MESSAGEID
WHERE m.MessageID=Messages.MessageID AND R.RecipientTypeID=2
for xml path(''), type).value('.', 'nvarchar(max)'), 1, 1, '')) as CC**
FROM Messages INNER JOIN Users
ON Messages.Sender = Users.UserID
INNER JOIN Recipients
ON Messages.MessageID = Recipients.MessageID
LEFT OUTER JOIN dbo.Projects
ON dbo.Messages.ProjectID = dbo.Projects.ProjectID
Left OUTER JOIN dbo.Customers on dbo.Projects.CustomerId =
dbo.Customers.CustomerID
Left outer join dbo.regions on dbo.Customers.RegionID =
dbo.Regions.RegionID
left outer join dbo.Phases on messages.phaseid = dbo.phases.phaseid
where (Messages.MessageTypeID=1)
and Projects.ProjectID <> '0'
order by Projects.ProjectName
但是在点击 next 时，它会导致如下错误：
'(' 附近的 WHERE 子句出错。
无法解析查询文本。
但是，如果我在 SQL Server 2008 R2 Management Studio 中运行上述相同的查询，它会运行良好并返回结果。
请提出我做错了什么。
谢谢
嗨，我为此使用了一种方法..即使用此查询（经过轻微修改）作为文件后面的 .cs 代码中的内联查询..但现在出现了另一个问题....即。 现在返回结果花费了太多时间。是因为我在查询中使用的函数吗？请为此提出一些解决方法..

ALTER FUNCTION [dbo].[fn_ForEmailReport]

BEGIN
DECLARE @List VARCHAR(8000)
set @List = (stuff((select ','+U.EMAIL

MESSAGES M ON R.MESSAGEID = M.MESSAGEID
WHERE m.MessageID=@MessageID AND R.RecipientTypeID=@RecipientTypeID
for xml path(''), type).value('.', 'nvarchar(max)'), 1, 1, ''))
RETURN @List;
结束
【问题讨论】：
-
你试过不带括号吗？比如 Messages.MessageTypeID=1 和 Projects.ProjectID '0'
-
我编辑了原始查询，请查看并提出建议
