11.0.2 doesn't seem to handle dashes when supplied as the first character of the JSON key. In JSON_VALUE and JSON_EXTRACT functions - it returns NULL even when the key is provided using the expected quoting.
CREATE TEMPORARY TABLE IF NOT EXISTS jsonTest AS
|
SELECT '{ "-1234" : "something", "12-34" : "else", "1234-" : "and", "1234" : "match" }' AS 'message'
|
;
|
|
SELECT JSON_SEARCH(message, 'one', 'something') AS t1_path, JSON_VALUE(message, JSON_UNQUOTE(JSON_SEARCH(message, 'one', 'something'))) AS t1_result,
|
JSON_SEARCH(message, 'one', 'else') AS t2_path, JSON_VALUE(message, JSON_UNQUOTE(JSON_SEARCH(message, 'one', 'else'))) AS t2_result,
|
JSON_SEARCH(message, 'one', 'and') AS t3_path, JSON_VALUE(message, JSON_UNQUOTE(JSON_SEARCH(message, 'one', 'and'))) AS t3_result,
|
JSON_SEARCH(message, 'one', 'match') AS t4_path, JSON_VALUE(message, JSON_UNQUOTE(JSON_SEARCH(message, 'one', 'match'))) AS t4_result
