Hello Sai,

1. You can use below query for first question

Create table #temp

(Id int, sName char(1))

insert into #temp values (1,'A')

insert into #temp values (2,'B')

insert into #temp values (3,'C')

insert into #temp values (4,'D')

insert into #temp values (5,'E')

insert into #temp values (6,'F')

select

sName, ROW_NUMBER() OVER(ORDER BY Id desc) AS Id

from #temp

Output will be as below

2. You can use below query for your second question

SELECT LEN('NETXCELLE') - LEN(REPLACE('NETXCELLE','E',''))

Thanks

Suraj
