olan Tüm tanımlamalar gibi tüm gösterimler başka bir sütunda tüm yetkinliklere ihtiyacımız var.

Answer 1

Yetkinlik dizesinin çok uzun olmadığını varsayarak, listagg()'u kullanabilirsiniz. Tavsiye ederim:

select t1.Designation, 
     (select listagg(t2.Competencies, ', ') within group (order by Competencies) 
     from test_2 
     ) as competencies 
from test_1 t1;
