MySQL：按前缀批量删除表格

没有直接可用的命令，不过可以通过mysql语法来组装，

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

然后执行该组装后的命令，比如从slowquery表中删除掉所有tmp_开头的表：

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

输出结果：

drop table tmp_201301,tmp_201302,tmp_201351,tmp_201352;
