phpmyadmin将文本从一个字段移到另一个字段 [英] phpmyadmin move text from one field to another

问题描述

我有一个包含2个字段的表格.电子邮件，额外

I have a table with 2 fields. Email, Extra

电子邮件字段中的每个条目都有一个名称，一个空格和一个姓氏.例如.拉维·奈多(Ravi Naidoo)

Every entry in the email field has a name then a space and then surname. eg. Ravi Naidoo

是否可以运行一个SQL查询，该查询会将姓氏移到Extra Table字段中，然后将其与空格一起从Email字段中删除?

Is there a SQL query that I would be able to run that would move the surname to the Extra Table field and then remove it from the Email field along with the space?

Eg. Email field: Ravi Naidoo

更改后将

Email field: Ravi
Extra field: Naidoo

我知道此查询会删除空格:

I know that this query removes the space:

UPDATE your_table SET email = REPLACE(email, ' ', '')

但是不确定如何将姓氏文本同时移动到Extra字段.

But am unsure how to move the surname text to the Extra field at the same time.

推荐答案

UPDATE your_table 
    SET extra = substring_index(email, ' ', -1), 
        email = substring_index(email,' ',1);
