Hi all,

DECLARE @j-2 NVARCHAR(max) = N'[{"Views":1,"Date":1493119613,"MediaCaption":"test"}]'
i want to add "size"="1000" to this array
SET @j-2 = JSON_MODIFY(@j,'append $[0].size' , 1000) SELECT @j-2
but It append "size":[1000]
how can Id add "size"="1000" instead of "size":[1000] ?

Interesting, not by a 2016 box right now but have you tried skipping the enumeration?

SET @j-2 = JSON_MODIFY(@j,'append $.size' , 1000) SELECT @j-2

Hi,

Have you tried enclosing the value in single-quotes?

I mean JSON_MODIFY(@j, 'append $.size', '1000')

Please let us know.

Please let us know.

My problem is about putting array instead of single value

"size"="1000" ==>ok
"size":["1000"] ==>not ok

Maybe without append:

DECLARE @j-2 NVARCHAR(max) = N'[{"Views":1,"Date":1493119613,"MediaCaption":"test"}]'

SET @j-2 = JSON_MODIFY(@j-2,'$[0].size' , 1000)

SELECT @j-2
