在mysql替换中将/替换为_
问题描述:
我有一个小代码,允许我将自定义名称从现有字段添加到新字段,但它不会将/(斜线)删除为 _(下划线).
I have a small code that allows me to add custom name to a new field from an existing field but it does not remove / (slash) to _ (underscore).
UPDATE `custom` SET custom_url = LOWER(REPLACE(REPLACE(REPLACE(Name, ' ', '_'), '(', ''), ')', ''));
我怎样才能重写这段代码,让它也允许我这样做?
How can I re-write this code so that it also allows me to do that?
答
正斜杠在 MySQL 中没有特殊含义,只需添加一个额外的替换即可.
Forward slashes have no special meaning in MySQL, just add an extra replace.
UPDATE `custom`
SET custom_url = LOWER(
REPLACE(
REPLACE(
REPLACE(
REPLACE(Name, ' ', '_')
, '(', '')
, ')', '')
,'/','_')
);
如果您想删除 /
则将 ,'/','_')
替换为 ,'/','')
> 在底部替换部分.
If you want to remove the /
then replace ,'/','_')
with ,'/','')
in the bottom replace part.
