Re: JSON_VALID

Hello,

can you tell my, why the first select returns false and the second select true?

first select:
select json_valid('{"configuration":"{\"action\":\"reading\"}"}'); -- return 0

second select:
select json_valid(concat('{"configuration":', json_quote('{"action":"reading"}'), '}')); -- return 1

I can get the value for the first select from select concat('{"configuration":', json_quote('{"action":"reading"}'), '}'), which I use in the second select.

Is it a bug?
I had tested it in MariaDB 10.2.13 and MariaDB 10.3.5.

Kind regards
K. Budde

Re: JSON_VALID

You need to run this instead:

select json_valid('{"configuration":"{\\"action\\":\\"reading\\"}"}'); -- return 1
