方法1:重建庫和表
用mysqldump --no-data把建表SQL導出來,然后drop database再create database,執行一下導出的SQL文件;
方法2:生成清空所有表的SQL
select CONCAT('TRUNCATE TABLE ',table_name,';') from information_schema.tables where TABLE_SCHEMA = 'db1'
導出到文件
select CONCAT('TRUNCATE TABLE ',table_name,';') into outfile '/website/truncatetable.sql' from information_schema.tables where TABLE_SCHEMA = 'db1'
