MySQL REPLACE不起作用

Question

I use this to replace \\" with " :

UPDATE wp_posts SET post_content = REPLACE (post_content, '\"', '"')

That query returns 0 row(s) affected and nothing happens.

What is wrong this this query?

Answer 1

你需要逃避反斜杠：

UPDATE wp_posts SET post_content = REPLACE (post_content, '\\"', '"')

Answer 2

反斜杠字符是MySQL中的转义字符，因此您需要像这样对自身进行转义：

UPDATE wp_posts SET post_content = REPLACE(post_content, '\\"', '"')

Answer 3

采用：

REPLACE(`post_content`, '\\"', '"')
