如何从mysql数据库中的每个表名称中删除前缀名称 [英] How to remove a prefix name from every table name in a mysql database

问题描述

我有一个joomla mysql数据库，其所有表名上的表名前缀均为"jos_".但我想将其从所有表格中删除.我知道如何一次重命名每个表，但是我有600个表.是否有运行SQL查询的简便方法来执行此操作.

I have a joomla mysql database with a table name prefix of "jos_" on all of my table names. But I would like to remove it from all of my tables. I understand how to rename each table, one at a time, but I have 600 tables. Is there an easy to run a sql query to do this.

如果有人有解决方案，请您发布我可以使用的确切SQL查询?

If someone has a solution, could you please post the exact sql query I can use?

推荐答案

您可以通过单个查询生成必要的语句:

You can generate the necessary statements with a single query:

select 'RENAME TABLE ' || table_name ||  ' TO ' || substr(table_name, 5) ||';'
from information_schema.tables

将该查询的输出保存到文件中，您便拥有了所需的所有语句.

Save the output of that query to a file and you have all the statements you need.

或者如果返回的是0和1而不是状态菜单，则此版本使用concat代替:

Or if that returns 0s and 1s rather the statemenets, here's the version using concat instead:

select concat('RENAME TABLE ', concat(table_name, concat(' TO ', concat(substr(table_name, 5), ';'))))
from information_schema.tables;
