MySQL中json_extract()函數的使用

作用：擷取資料庫中指定欄位中儲存的json資料中的某個欄位對應的值

要做做什麼？（根據資料庫中相關表欄位中儲存的json格式的資料，然後以SQL語句的形式取出其中指定key對應的值，最終整理彙總為一張檢視供以後的方便使用）

一、初始化

1、初始化表結構

CREATE TABLE `cus_history` (

  PRIMARY KEY (`id`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=3835 DEFAULT CHARSET=utf8 COMMENT='客戶歷史檔案';

2、插入相關資料
