Are you running into any issues when using charindex and substring? In any case, the following does not use either of those functions:
DECLARE @x VARCHAR(256) = 'http://www.mysite.com/Default.aspx?TabId=330&EntryId=1';
SELECT STUFF(@x,1,PATINDEX('%&EntryId%',@x),'')

I tried the below and it worked.

DECLARE @x VARCHAR(256) = 'http://www.mysite.com/Default.aspx?EntryId = 1&a=1&TabId=330';

--another query string combination
/*DECLARE @x VARCHAR(256) = 'http://www.mysite.comDefault.aspx?TabId=330&EntryId = 1&a=1';*/

SELECT STUFF(@x,1,PATINDEX('%EntryId%',@x)-1,'')
select LTRIM(RTRIM(Replace(REPLACE(SUBSTRING(STUFF(@x,1,PATINDEX('%EntryId%',@x)-1,''),0,
(case when CHARINDEX('&',STUFF(@x,1,PATINDEX('%EntryId%',@x)-1,''),1)=0 then 100 else CHARINDEX('&',STUFF(@x,1,PATINDEX('%EntryId%',@x)-1,''),1) end)
),'EntryId',''),'=','')))

Thanks
