Question

I have a table

columns:Name,Role,Dept

A person can have many roles. So while retrieving the data i want the roles column to be in CSV if a person has more than one role.

 Name Role          Dept 
 jose Role1,Role2   PWD

Assuming all other details except the roles for the records are same.

Thanks

This will do the trick for you.

select
    t3.Name,
    left(t3.Roles, len(t3.Roles)-1) as Roles,
    t3.Dept
from
    (select
            t2.Name,
            t2.Dept,
            (select t1.[Role] + ','
             from Table1 as t1
             where
                t1.Name = t2.Name and
                t1.Dept = t2.Dept
             order by t1.[Role]
             for xml path('')) as Roles
        from Table1 as t2
        group by t2.Name, t2.Dept) as t3

This is taken from the first example in “The blackbox XML methods” from this page
https://www.simple-talk.com/sql/t-sql-programming/concatenating-row-values-in-transact-sql/

The inner query builds the list of Roles as an xml. The xml path(”) parameter is empty and therefor you do not get the xml markup but only the comma separated list.

The outer query is only there to remove the comma at the end of each line.

Group by t2.Name, t2.Dept makes sure that you will only get one row for each unique combination of Name+Dept.
