Description
Following on from the comment about the non-working example in MDEV-12877 that MySQL and MariaDB behave the same - they don't in that MySQL gives an error, MariaDB a warning. Is this desirable? Doesn't an error make more sense here?
MySQL 5.7:
SELECT JSON_SEARCH(@json, 'onee', 'AB');
|
ERROR 3154 (42000): The oneOrAll argument to json_search may take these values: 'one' or 'all'.
|
|
|
select json_extract(json_object('truc',json_array('machin',4,json_object('chose','XML'))),json_search(json_object('truc',json_array('machin',4,json_object('chose','XML'))),'one','XML')) as Result;
|
ERROR 3143 (42000): Invalid JSON path expression. The error is around character position 1.
