declare @t table(codetype varchar(10), code int, Value int);
insert into @t(codetype, code, Value)
values('Test1',1,2),
('Test1',2,3),
('Test2',4,5),
('Test2',6,7);


SELECT 
   N'{' + 
   STUFF(
      (
      SELECT DISTINCT N',"' +  t.codetype + '":' +  ca.jsn
      FROM @t AS t
      CROSS APPLY (SELECT t2.code, t2.Value FROM @t t2 WHERE t2.codetype = t.codetype FOR JSON PATH ) ca(jsn)
      FOR XML PATH('')
      ), 1, 1, N''
   ) + N'}'
 AS Result;
