Je voudrais revenir un jeu de résultats que les regards comme ceci:

Merci à l'avance

Answer 1

Declare @Table table (id int, type int, text varchar(50)) 
Insert Into @Table values 
(1, 1, 'C#'), 
(2, 1, 'VB'), 
(3, 1, 'Java'), 
(4, 1, 'JQuery'), 
(5, 1, 'SQL'), 
(6, 2, 'Basic'), 
(7, 2, 'Intermediate'), 
(8, 2, 'Advance'), 
(9, 2, 'Not Applicable') 


Select A.Text+'/'+B.Text 
From @Table A 
Join @Table B on (A.Type=1 and B.Type=2) 
Order By 1
