Answer

This is how you can do it.

Declare a temp table with char and name, then using substring function of sql put the first character and name in the table. From there you can group the results.

Here is the sample for you for mssql server

declare @tbl table(ch char(1), name nvarchar(50))

insert into @tbl
select ( SELECT SUBSTRING(e.address, 1, 1)),address from Emp2 e

select ch,name From @tbl
group by ch, name

select distinct t.[ch],
  STUFF((SELECT distinct ', ' + t1.name
         from @tbl t1
         where t.[ch] = t1.[ch]
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,2,'') department
from @tbl t
