Maria DB 更新和替换

Question

运行此命令时我收到错误消息：

UPDATE catalog_product_entity_text
SET value = REPLACE (value, 'xxxxx') 
WHERE value LIKE 'yyyyy'; 

错误： #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ')' at line 1

有任何想法吗？

谢谢

我用表达式得到了同样的错误：

UPDATE catalog_product_entity_tex
     SET value = REPLACE (value, 'yyyyy', 'xxxxx')
     WHERE value LIKE '%yyyyy%';

解决方案是使用别名：

UPDATE catalog_product_entity_tex c
     SET c.value = REPLACE (c.value, 'yyyyy', 'xxxxx')
     WHERE c.value LIKE '%yyyyy%';
