;with SCC_cTE(ID ,Name)

AS (SELECT 1, 'srinivas' union all

select 2, 'ravikumar' union all

select 3, 'jaipal' union all

select 4, 'ravisekhar' union all

select 5, 'ramugopal' union all

select 6, 'harikuma')

select id, name, SUBSTRING(REVERSE(name), 3, 1) as output

from SCC_cTE

Society has varying and conflicting interests; what is called objectivity is the disguise of one of these interests - that of neutrality. But neutrality is a fiction in an unneutral world. There are victims, there are executioners, and there are bystanders... and the 'objectivity' of the bystander calls for inaction while other heads fall.

substring reads from Left to Right, not Right to Left as some Languages from non English speaking countries might.

so when you put '3' in to your substring, your asking for the 3rd character from the left.

;with cte(id , name) as (

select 1 , 'srinivas'

union select 2 , 'ravikumar'

union select 3 , 'jaipal'

union select 4 , 'ravisekhar'

union select 5 , 'ramugopal'

union select 6 , 'harikuma'

)

select id,SUBSTRING(name,LEN(name) - 2,1) from cte

DECLARE @string varchar(10) = 'aapail'

SELECT SUBSTRING(REVERSE(@string),3,1)

hi,

before finding sub string you should trim the data otherwise it takes empty data also.

select id,SUBSTRING(Reverse(LTRIM(RTRIM(name))),3,1) from emp

hi,
before finding sub string you should trim the data otherwise it takes empty data also.
select id,SUBSTRING(Reverse(LTRIM(RTRIM(name))),3,1) from emp

;WITH Sampledata (id, name) AS (

SELECT 1 , 'srinivas ' UNION ALL

SELECT 2 , 'ravikumar ' UNION ALL

SELECT 3 , 'jaipal' UNION ALL

SELECT 4 , ' ravisekhar' UNION ALL

SELECT 5 , ' ramugopal' UNION ALL

SELECT 6 , ' harikuma ' )

-- LTRIM() isn't necessary:

SELECT

id,

name,

NameShowingPadding = '|' + name + '|',

Fails = SUBSTRING(REVERSE(name),3,1),

Oneway = SUBSTRING(REVERSE(RTRIM(name)),3,1),

Anotherway = LEFT(RIGHT(RTRIM(name),3),1)

FROM Sampledata
