MySQL 批量删除table

转并修改自：https://www.cnblogs.com/init-007/p/10955110.html

原理：通过mysql语法组装批量删除的命令

SELECT CONCAT( \'DROP TABLE \', GROUP_CONCAT(table_name) , \';\' ) 
AS statement FROM information_schema.tables 
WHERE table_schema = \'database_name\' AND table_name LIKE \'myprefix_%\';

例如 这里要删除database thread 下的file-开头的table:

 select concat("drop table thread.",group_concat(table_name),";")
 as statement from information_schema.tables
 where table_schema="thread" and table_name like "file%";

 

 

 再执行生成的批量删除语句：

drop table thread.file1,file10,file100,file11,file12,file13,file14,file15,file16,file17,file18,file2,file3;
