如何从mysql中的数据行中删除换行符? [英] How to remove new line characters from data rows in mysql?

问题描述

我可以遍历php脚本中的所有行并这样做

I can loop through all of the rows in a php script and do

UPDATE mytable SET title = "'.trim($row['title']).'" where id = "'.$row['id'].'";

并修剪可以删除\ n

and trim can remove \n

但是我只是想知道是否可以在一个查询中完成相同的事情?

But I was just wondering if something same could be done in one query?

 update mytable SET title = TRIM(title, '\n') where 1=1

能行吗?然后，我可以执行此查询而无需遍历！

will it work? I can then just execute this query without requiring to loop through!

谢谢

(PS:我可以测试它，但是表很大，并且不想弄乱数据，所以请考虑一下您之前是否已经测试过类似的东西)

(PS: I could test it but table is quite large and dont want to mess with data, so just thought if you have tested something like this before)

推荐答案

您的语法错误:

update mytable SET title = TRIM(TRAILING '\n' FROM title)
