MySQL，URL 编码 varchar 列

转载作者：行者123 更新时间：2023-11-29 01:31:02

我们有一个第三方系统，可以将数据从他们的服务器提取到 Web 客户端。服务器连接到 MySQL 数据库。正在通过 JSON 字符串传输数据。显然，其中一列的字符在引入 JSON 字符串时会破坏格式。我唯一的办法是修复列中的数据。我在考虑对所有内容进行 URL 编码。在 MySQL 中有没有一种简单的方法可以做到这一点？

这是对封闭系统行为的有根据的猜测。我将向数据表 (column_b) 添加另一列。然后我想用来自 column_a 的 URL 编码数据填充它。像这样: UPDATE mytable set column_b = some_url_encode_function(column_a);

最佳答案

基于来自未解码函数的类似响应，我提供了我修改为编码的下一个代码:

-- =======================================================
-- This is a function to replace bad for good characters, this function works based in a table with the mapping
-- =======================================================
-- drop the table if it exists
DROP TABLE IF EXISTS urlcodemap;

PRIMARY KEY (`id`)
