@lenin

previously i worked on fixed lenth part of string

so i used to use substring and charindex with a particular length

but here the string lenght between 1st'\' and fourth '\' is varying in all the rows ..i'e 1st row string lenght varies with 2nd row and all

so i couldn't figure t out how to use that functions for that type of rows

Care to post what you had? I have a solution, it may not be the best (Back to substring over stuff), but I am curious as to what you have.

Do all the values in the column have at least four \'s?

Good question, a follow up question is do you just want to get rid of everything past the last "\"?

String = \\abc\def\ghi\jklmnop

expected result = \\abc\def\ghi

DECLARE @STR NVARCHAR(30)

SET @STR = '\\abc\xyz\wzy\123'

SELECT SUBSTRING(@str, 1, LEN(@str) - CHARINDEX('\', REVERSE(@str)))

I am posting my solution.

All we wanted is for you to post the code you have written to try and solve your problem.

Here is my solution using the dbo.DelimitedSplit inline TVF. Use the site search box and type DelimitedSplit.txt to find the thread where I have it uploaded.

create table #TestTab (

Col1 varchar(32)

);

insert into #TestTab

select '\\abc\tri\eds\rf' union all

select '\\fd\tri\ef\' union all

select '\\ghij\tri\gf\rf\k';

select

stuff(

(select '\' + ds.Item from #TestTab t1 cross apply dbo.DelimitedSplit(t1.Col1,'\') ds where ds.ItemID <= 5 and t1.Col1 = t2.Col1 for xml path (''))

,1,1,'')

from

#TestTab t2;

Any one else with a solution, please post it now. Let's see what other options we have for this solution.
