我现在不知道，为什么我在这个 sql 请求中有错误 [重复]

Question

UPDATE `vjprf_jshopping_manufacturers` 
SET `meta_title_en-GB`='Buy products from the manufacturer '.`name_en-GB`.' 
in Ukraine at wholesale prices | Deps' WHERE `manufacturer_id`=3

我需要在meta_title_en-GB='some text (place to insert name_en-GB) some text'中插入name_en-GB

错误编号 #1064

点用于 PHP 中的字符串连接。在 MySQL 中使用CONCAT 函数：

UPDATE vjprf_jshopping_manufacturers
SET meta_title_en-GB = CONCAT('Buy products from the manufacturer ', name_en-GB,
    ' in Ukraine at wholesale prices | Deps')
WHERE
    manufacturer_id = 3;
