Select join in the same collumn

[Alexandre Salomé]

Hello!

I have 2 tables as exemple:
- "table A" with name and age
- "table b" with name_boss and employee

- I have (table A) name='John Doe' that is (table A) name_boss='John Doe' boss of
'employee1' and 'employee2'

Is there a select command to return 'employee1' and 'employee2' in the
same collumn :

exemple:

boss | employee
John Doe | employee1, employee2


I tried search a lot in web but I cant find if exist

Thank you
