我的表格数据如下:
SessionRefere
http://www.google.com/url?sa=t&rct=j&q=aaa bbb&source=web&cd=1&cad=rja&sqi=2&ved=0CB4QFjAA&url=http://www.abc.com/&ei=QFR0UM-JKIrQrQfsuoG4CQ&usg=AFQjCNExYcKkcvobBbktLGNksptf1giQRw

这只是样本数据。有很多这样的案例。所以在计算之前我想要原始的网址部分。
我使用此查询来获取数据。
DECLARE @temp table(RefPage nvarchar(200))
insert into @temp
SELECT
CASE CHARINDEX( '?', SessionReferer)
WHEN 0 THEN SessionReferer
ELSE LEFT(SessionReferer, CHARINDEX( '?', SessionReferer) - 1) END AS RefPage
FROM Tracker WHERE [start] between '1-1-2010' and '1-1-2015' and SessionReferer<> ''
select distinct RefPage, count(*) as [VisitTime] from @temp
group by RefPage
order by [VisitTime] desc
我的结果是:
SessionRefere VisitTime
http://www.google.com/url 2
http://www.google.com/reader/view/ 1
但我想要一个结果:
SessionRefere VisitTime
http://www.google.com 3
是否有可能获得欲望结果或我的方式错误?感谢。

尝试在CHARINDEX('/',SessionReferrer,9)
select
case when CHARINDEX('/',SessionReferrer,9) = 0
then SessionReferrer
else left(SessionReferrer, CHARINDEX('/',SessionReferrer,9)-1)
end,
count(*)
from Tracker
group by
case when CHARINDEX('/',SessionReferrer,9) = 0
then SessionReferrer
else left(SessionReferrer, CHARINDEX('/',SessionReferrer,9)-1)
end
(我懒得假设所有推荐人都以http://或https://开头)

试试这个
Declare @T Table(URL Varchar(MAX))
Insert Into @T Values('http://www.google.com/url?sa=t&rct=j&q=aaa bbb&source=web&cd=1&cad=rja&sqi=2&ved=0CB4QFjAA&url=http://www.abc.com/&ei=QFR0UM-JKIrQrQfsuoG4CQ&usg=AFQjCNExYcKkcvobBbktLGNksptf1giQRw')
Insert Into @T Values('http://www.google.com/reader/view/?hl=es&tab=Xq&at=RTknd_lBUUnvNqan2641EA')
Insert Into @T Values('http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=5&cad=rja&ved=0CEgQFjAE&url=http://www.abc.com/ppp.aspx&ei=dmd0UOO9AYnY4QS1sYGwBw&usg=AFQjCNGIFcJUUSVpl_ZiZoSWDP2LkIagtw')

我在这里:
表示字符串@test:
我在URL中分隔'//'和'/'之间的字符串
根据给定的URL
Declare @test nvarchar(100)
Declare @http nvarchar(8)
set @test = 'http://www.google.com/url?sa=t&rct=j&q=aaa bbb&source=web&cd=1&cad=rja&sqi=2&ved=0CB4QFjAA&url=http://www.abc.com/&ei=QFR0UM-JKIrQrQfsuoG4CQ&usg=AFQjCNExYcKkcvobBbktLGNksptf1giQRw'
declare @length int
declare @start int
declare @subString nvarchar(100)
set @start =( select CharIndex('//', @test))
set @http = SUBSTRING(@test, 0 , @start)
set @length = Len(@test)
set @subString = SUBSTRING ( @test ,@start+2 , @length )
set @start =( select CharIndex('/', @subString))
set @subString = SUBSTRING ( @subString ,0 , @start )
set @subString = @http+'//'+ @subString
