IRELAND/IRLANDE
GREECE/GRÈCE
DENMARK/DANEMARK

Now i want only the countrynames before this special character'/' so the out put should look like this..

IRELAND
GREECE
DENMARK

please help. Thanks in advance

Answer 1

 create table #t(name nvarchar(40))
insert into #t values('IRELAND/IRLANDE')
,('GREECE/GRÈCE')
,('DENMARK/DANEMARK')


select substring(name,0,CHARINDEX('/',name)) from #t

Answer 2

Why LEN(names)-CHARINDEX('/',names)?
try using CHARINDEX('/',names)+1 instead.

As far as I remember, SUBSTRING's third variables should be the length of the desired output string.

Answer 3

A more complex query to help you out:

DECLARE @Text     VARCHAR(50) = 'IRELAND/IRLANDE GREECE/GRÈCE DENMARK/DANEMARK'
    SELECT
 SUBSTRING(SUBSTRING(@Text,0,CHARINDEX(' ',@Text,0)),0,CHARINDEX('/',@Text,0))
 +  
 SUBSTRING(SUBSTRING(@Text,CHARINDEX(' ',@Text,0),CHARINDEX(' ',@Text,0)),0,CHARINDEX('/',@Text,0))
 + ' '
 +
 REPLACE(REVERSE(SUBSTRING(REVERSE(@Text),CHARINDEX('/',@Text,0) + 1 ,CHARINDEX('/',@Text,0))),'/', ' ')
