我用json_encoded将数据插入数据库.
现在我想搜索“功能”,但我不能.
现在我想搜索“功能”,但我不能.
MySQL查询：
SELECT `id`,`attribs_json`
FROM `products`
WHERE `attribs_json` REGEXP '"1":{"value":[^"3"$]'
这个查询显示了所有的行与键“1”,值是任何东西,不是值“3”
我的资料是：
{"feature":{"1":{"value":"["2","3"]"},"2":{"value":["1"]},"5":{"value":""},"3":{"value":["1"]},"9":{"value":""},"4":{"value":"\u0633\u0627\u062a\u0646"},"6":{"value":""},"7":{"value":""},"8":{"value":""}
},"show_counter":"0","show_counter_discount":""
}}
如果你有MysqL版本> = 5.7,那么你可以试试这个 –
SELECT JSON_EXTRACT(name,"$.id") as name FROM table WHERE JSON_EXTRACT(name,"$.id") > 3
输出 –
+-------------------------------+
| name |
+-------------------------------+
| {"id": "4","name": "Betty"} |
+-------------------------------+
