phpmyadmin 将文本从一个字段移动到另一个字段

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字，一个空格，然后是姓氏.例如.拉维·奈杜

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

是否有我可以运行的 SQL 查询将姓氏移动到额外表字段，然后将其与空格一起从电子邮件字段中删除?

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

更改后会

Email field: Ravi
Extra field: Naidoo

我知道这个查询删除了空格:

I know that this query removes the space:

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

但我不确定如何同时将姓氏文本移动到额外字段.

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);
