Subject: Upper / lower case keys in JSON objects
Date: Fri, 25 Jul 2025 13:26:16 +0100
Message-ID: <CAAm-KOuSB+mS=k3LjYLCwpkv64EpWqF8OCA=jzwCofnjyqsgXA@mail.gmail.com> (raw)
Hi all
Apologies for any unexpected protocol exceptions, I do not post to mailing
lists very often
I have been trying to work with JSON objects and noticed I could not get
the function json_to_record to produce results, unless I had the key values
in lower case, through testing what works.
I completed a search, but could not find any pointer (except for some front
end comments on labels being all upper or all lower case)
Could anybody comment if the postgres standard is to have key labels in
lower case?
Many thanks for any help you can provide
Mark
query:
select * from json_to_record('{"secLvl": 13, "firBal": "somethi", "firLvl":
"C", "thiLvl": "A", "fourLvl": 2}'::json) as x(seclvl int, firbal text,
firlvl text
, thilvl text, fourlvl int);
result:
seclvl | firbal | firlvl | thilvl | fourlvl
--------+--------+--------+--------+---------
| | | |
