mysql - 如何在mysql中删除前导和尾随斜杠

Question

我需要从表格菜单中的 url 字段中查询 remove /

原表

menuname url
home     /home/
about    /home/about/

要求

menuname   url
home       home
about      home/about

Answer 1

这是从字段中删除尾部斜杠的方法：

UPDATE `table_name` SET `field_name`=TRIM(TRAILING '/' FROM `field_name`)

Answer 2

SELECT TRIM( BOTH  '/'    FROM  '/bar/' )     

编辑

SELECT TRIM(BOTH  '/' FROM link ) FROM menu

Answer 3

见http://dev.mysql.com/doc/refman/5.5/en/string-functions.html#function_trim

例子：

SELECT TRIM(BOTH '/' FROM home, about) FROM 'table_name';
