Mysql转义函数；使用选择查询生成更新查询

Question

你好我有一个开发服务器和生产服务器，两者都是相同的数据库。表格产品将在两台服务器上进行编辑，但仅在不同的列上进行编辑开发:id模型图片生产:价格和缺货

我不想为此使用 php。

所以我为开发服务器创建了以下查询

SELECT CONCAT( "UPDATE `products` SET `products_id` = ", products_id, ",`products_model` = '", REPLACE( products_model, "'", "\'" ) , "',`products_image` = '", products_image, "' WHERE `products`.`products_id` = ", products_id, ";" )
FROM `products` 

此查询返回生产服务器的查询

UPDATE `products` SET `products_id` = 60,`products_model` = 'CT'257',`products_image` = 'ct_black01.jpg' WHERE `products`.`products_id` = 60;
UPDATE `products` SET `products_id` = 59,`products_model` = 'CT"255',`products_image` = 'ct_black01.jpg' WHERE `products`.`products_id` = 59;
UPDATE `products` SET `products_id` = 58,`products_model` = 'CT/242',`products_image` = 'ct_black01.jpg' WHERE `products`.`products_id` = 58;
UPDATE `products` SET `products_id` = 57,`products_model` = 'CT221',`products_image` = 'ct_black01.jpg' WHERE `products`.`products_id` = 57;

问题是当 product_model 包含 ' 或 "或两者时我需要转义字段那么这个查询将失败

我如何在没有 php 的情况下执行 mysql_real_escape？

谢谢

Answer 1

怎么样

REPLACE(REPLACE(products_model, "'", "\\'"), '"', '\\"')

这将用转义的单引号和双引号替换所有的单引号和双引号。
