I have a table like this:
+--------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+--------+-------------+------+-----+---------+----------------+
| Id | int(11) | NO | PRI | NULL | auto_increment |
| codigo | varchar(16) | NO | UNI | NULL | |
| names | json | NO | | NULL | |
+--------+-------------+------+-----+---------+----------------+
mysql> select * from test02;
+----+---------------+-------------------------------------------------------------------------------------------------------------------------------------------+
| Id | codigo | names |
+----+---------------+-------------------------------------------------------------------------------------------------------------------------------------------+
| 1 | 8413951000500 | [{"name": "QUITA ATASCO REF:43ATASC", "locale": "ES"}, {"name": "通管道液体", "locale": "ZH"}] |
| 2 | 8608699005201 | [{"name": "DESATASCADOR 1.4M K100482", "locale": "ES"}, {"name": "摇把疏通器", "locale": "ZH"}, {"name": "changes", "locale": "EN"}] |
| 3 | 8414926294702 | [{"name": "CESTA MIMBRE MULTIUSOS", "locale": "ES"}, {"name": "竹篮子", "locale": "ZH"}] |
+----+---------------+-------------------------------------------------------------------------------------------------------------------------------------------+
3 rows in set (0,01 sec)
I want unique key in "locale" for update o insert.
and I want can get "name" key/value when search like < where names->'$'->'locale' = "ES" >..
