create table [dbo].[trades]( [_id] [int] identity(1,1) not null, [trade] [nvarchar](max) null,

my json formatted below , stored in trade column

{   "direction": "short",   "powerbars": 2,   "powerbarstime": [     "2016-11-10t20:25:32.481424-05:00",     "2016-11-10t20:44:01.8993031-05:00"   ] }

since powerbarstime list in json, have provide index print it. don't know how many entries eb there in list. there way merge list part of json , return comma delimited column?

i have print

select        _id,  json_value(trade, '$.powerbars') powerbars, json_value(trade, '$.powerbarstime[0]') powerbarstime1, json_value(trade, '$.powerbarstime[1]') powerbarstime2            dbo.trades order _id desc
