如何使用MySQL删除两个固定字符串之间的随机字符串？

Question

以下是我的MySQL数据库中的一些短语：

I love swimming and writing.
I love shopping and writing.
I love playing games and writing.

如何将其更改为

I love writing.
I love writing.
I love writing.

Answer 1

不要将其视为删除中间的字符串，就像将常量字符串设置为与模式匹配的任何内容一样：

UPDATE my_table
SET    my_column = 'I love writing.'
WHERE  my_column LIKE 'I love% writing.'
