I am not sure if this is what you want, but it is what I read.

UPDATE YourTable

SET Column1 = Column2

WHERE YourWhereClause

i need a query to eliminate that highlited part of the string so that after elimination it looks like the row in colum2

My query will do that. you want col1 to be the same as col2.

Do you mean, something like:

select replace ( '\\xyz.se.df.a.b\fgd\' , '.se.df.a.b' , '' )

Here is an example to get rid of everything after the first "." and before the third "\". You provided very little info, so I don't know if that's exactly what you're wanting to do but it was my best guess.

select stuff('\\xyz.se.df.a.b\fgd\', charindex('.', '\\xyz.se.df.a.b\fgd\'), charindex('\', '\\xyz.se.df.a.b\fgd\', 3) - charindex('.', '\\xyz.se.df.a.b\fgd\') - 1, '')

Actually, I should do it like this so it may be more clear:

declare @vc_string varchar(20);

select @vc_string = '\\xyz.se.df.a.b\fgd\';

select stuff(@vc_string, charindex('.', @vc_string), charindex('\', @vc_string, 3) - charindex('.', @vc_string) - 1, '');

@pablo-2

Thanks for ur help

what if i got different rows in that column like

example:

Colum1

\\xyz.ed.kl.e.a\fgd\\rsq.fd.ij.g.b\fgd\\wes.as.gh.c.b\fgd\\abc.er.tf.h.d\fgd

what if i want to get the rows with the part of the string starting from like .ed.kl.e.a i mean starting from . to \ eliminated in all the rows.

Cory E. SSCertifiable Points: 7076 More actions · Answer 9

DECLARE @STR NVARCHAR(30)

SET @STR = '\\xyz.ed.kl.e.a\fgd\'

SELECT SUBSTRING(@str, 1, CHARINDEX('.', @STR) - 1) + SUBSTRING(@str, CHARINDEX('\', @STR, 3), 4)

, SUBSTRING(@str, 1, CHARINDEX('.', @STR) - 1) + SUBSTRING(@str, CHARINDEX('\', @STR, CHARINDEX('.', @STR) - 1), 4)

My result for the one test is:

\\xyz\fgd

Mine was more efficient. Plus STUFF is simply cool and underused.

Props on the STUFF, in 12 years of doing SQL, that's the first time I have ever seen it used except in BOL/MSDN examples.

Heh, thanks.

And here is the whole example:

declare @t_temp table

(Column1 varchar(50));

insert into @t_temp

select '\\xyz.ed.kl.e.a\fgd\' union

select '\\rsq.fd.ij.g.b\fgd\' union

select '\\wes.as.gh.c.b\fgd\' union

select '\\abc.er.tf.h.d\fgd\';

/* and the actual function ... */

select stuff(Column1, charindex('.', Column1), charindex('\', Column1, 3) - charindex('.', Column1) - 1, '')

from @t_temp;
