Обсуждение: json_to_recordset not working with camelcase json keys

Hi all,

We tried to extract from a json with camel case keys values, but unfortunat=
elly they are not mapped.

Testcase: (PostgreSQL 9.4.5)

select * from json_to_recordset('[{"aB":1,"bC":"foo"},{"aB":"2","cD":"bar"}=
]') as x(aB int, bC text);

Expected:
aB | bC
1   | foo
2   | null

Actual:
aB  | bC
null | null
null | null

Does anyone knows if this is a bug?
Thanks for any help.

Kind regards,
Daniel

Not a bug, I believe. You probably meant this:

select * from json_to_recordset('[{"aB":1,"bC":"foo"},
                                  {"aB":"2","cD":"bar"}]')
              as x("aB" int, "bC" text, "cD" text);
 aB | bC  | cD
----+-----+-----
  1 | foo |
  2 |     | bar
(2 rows)

Unquoted identifiers are lowercased in postgres, so for camel case
identifiers you would need double quotes.

HTH,

Joe
