Remove array from json object stored in SQL Server column - json

Question

If I have the following JSON stored in a column in SQL Server:
declare #json nvarchar(max) = '[{"id": "1", "name": "test1"},{"id": "2", "name": "test2"},{"id": "3", "name": "test4"}]'
how can I remove an array where Id:=1 ?
I want to get the following result:
[{"id": "2", "name": "test2"},{"id": "3", "name": "test4"}]

Answer 1

try this:
declare #json nvarchar(max) = '[{"id": "1", "name": "test1"},{"id": "2", "name": "test2"},{"id": "3", "name": "test4"}]';
DECLARE #IdTobeRemoved INT =1;
DECLARE #StartIndex INT
DECLARE #EndIndex INT
DECLARE #tempjson nvarchar(max)
SELECT #StartIndex = CHARINDEX('"id": "'+CONVERT(VARCHAR(10),#IdTobeRemoved)+'"',#json)-2
SELECT #tempjson = STUFF(#json, 1, #StartIndex, '')
SELECT #EndIndex =
CASE WHEN SUBSTRING(#tempjson,CHARINDEX('}',#tempjson)+1,1)=']'
THEN CHARINDEX('}',#tempjson)+1
ELSE CHARINDEX('}',#tempjson)+2
END
SELECT REPLACE(REPLACE(#json,SUBSTRING(#tempjson,0,#EndIndex),''),'},]','}]')
