我在 SSRS 2016 的报告生成器中打开一个报告文件（在 SSRS 2014 中创建），以便将其保存到报告管理器站点或预览它，我收到此错误：
System.Web.Services.Protocols.SoapException: There was an exception running
the extensions specified in the config file. ---> System.Web.HttpException:
Maximum request length exceeded.

at System.Web.Services.Protocols.SoapServerProtocol.Initialize()

报告管理器网站上的上传选项也不起作用。
我们如何过滤别名？例如，在下面的查询中，对于别名 OLB，如果我们想说 WHERE OLB > 0
SELECT
loan.lnr
,loan.lamount - SUM (memrepay.mprinc) AS OLB
,lstatus
FROM
loan
LEFT OUTER JOIN memrepay
ON loan.lnr = memrepay.lnr
WHERE
loan.tstart >= N'2013-07-07T14:00:00'
GROUP BY loan.lnr, lamount, lstatus
Order By lnr
你能告诉我这两者有什么区别吗？我尝试将两者都用于比较两个表，但是结果有点不同：
SELECT a.CustID FROM tbl1 AS a
WHERE EXISTS (SELECT b.CustID FROM tbl2 b WHERE (a.CustID=b.CustID))
该查询结果为178行。但是，下面的查询将导致162行。
SELECT a.CustID FROM tbl1 AS a
INTERSECT
SELECT b.CustID FROM tbl2 AS b
