SELECT Id AS Id,
CASE WHEN ISNULL(FatherId,0) <> 0 OR ISNULL(MotherId,0) <> 0 THEN
CAST(FatherId AS VARCHAR(25)) + ',' + CAST(MotherId AS VARCHAR(25)) END AS parents,
EnglishName AS title,
[Description] AS Description,
[Image] AS Image FROM TreeView

I tried but result is {"Id":5,"parents":"1,2","title":"AJhir Ali"}
but I am expecting this {"Id":5,"parents":[1,2],"title":"AJhir Ali"}
