多个网站共用一个Mysql数据库时,为使数据库管理不混乱,一般采用不同的网站使用不同前缀名的方式进行区分。而如何批量修改已有数据库的前缀名呢?全部导出修改后再导入?还是一个表一个表的修改?今天我要介绍的是相对简单的批量修改数据库中表前缀的方法,适用于修改数据库中相同前缀且数据表较多的情况。

此例中假定修改名为“www_sdck_cn”的数据库中前缀为“phpcms_”的表,并将所有符合条件表的前缀修改为“sdck_”。

1、用phpMyAdmin打开要修改前缀的数据库www_sdck_cn,执行以下SQL语句(其中加粗斜体字是需要根据实际需求替换的):

Select CONCAT( 'ALTER TABLE ', table_name, ' RENAME TO ', replace(table_name,'phpcms_','sdck_'),';')

from information_schema.tables

where TABLE_SCHEMA = 'www_sdck_cn' and table_name LIKE 'phpcms_%';
