谷歌主题总是把我带到这个SO问题，所以这里是工作的mysql代码，删除表和视图:

DROP PROCEDURE IF EXISTS `drop_all_tables`;

DELIMITER $$
CREATE PROCEDURE `drop_all_tables`()
BEGIN
    DECLARE _done INT DEFAULT FALSE;
    DECLARE _tableName VARCHAR(255);
    DECLARE _cursor CURSOR FOR
        SELECT table_name
        FROM information_schema.TABLES
        WHERE table_schema = SCHEMA();
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET _done = TRUE;

    SET FOREIGN_KEY_CHECKS = 0;

    OPEN _cursor;

    REPEAT FETCH _cursor INTO _tableName;

    IF NOT _done THEN
        SET @stmt_sql1 = CONCAT('DROP TABLE IF EXISTS ', _tableName);
        SET @stmt_sql2 = CONCAT('DROP VIEW IF EXISTS ', _tableName);

        PREPARE stmt1 FROM @stmt_sql1;
        PREPARE stmt2 FROM @stmt_sql2;

        EXECUTE stmt1;
        EXECUTE stmt2;

        DEALLOCATE PREPARE stmt1;
        DEALLOCATE PREPARE stmt2;
    END IF;

    UNTIL _done END REPEAT;

    CLOSE _cursor;
    SET FOREIGN_KEY_CHECKS = 1;
END$$

DELIMITER ;

call drop_all_tables();

DROP PROCEDURE IF EXISTS `drop_all_tables`;

下面是修改后的SurlyDre的存储过程，这样外键就被忽略了:

DROP PROCEDURE IF EXISTS `drop_all_tables`;

DELIMITER $$
CREATE PROCEDURE `drop_all_tables`()
BEGIN
    DECLARE _done INT DEFAULT FALSE;
    DECLARE _tableName VARCHAR(255);
    DECLARE _cursor CURSOR FOR
        SELECT table_name 
        FROM information_schema.TABLES
        WHERE table_schema = SCHEMA();
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET _done = TRUE;

    SET FOREIGN_KEY_CHECKS = 0;

    OPEN _cursor;

    REPEAT FETCH _cursor INTO _tableName;

    IF NOT _done THEN
        SET @stmt_sql = CONCAT('DROP TABLE ', _tableName);
        PREPARE stmt1 FROM @stmt_sql;
        EXECUTE stmt1;
        DEALLOCATE PREPARE stmt1;
    END IF;

    UNTIL _done END REPEAT;

    CLOSE _cursor;
    SET FOREIGN_KEY_CHECKS = 1;
END$$

DELIMITER ;

call drop_all_tables(); 

DROP PROCEDURE IF EXISTS `drop_all_tables`;

这是一个基于游标的解决方案。有点长，但可以作为单个SQL批处理:

DROP PROCEDURE IF EXISTS `drop_all_tables`;

DELIMITER $$
CREATE PROCEDURE `drop_all_tables`()
BEGIN
    DECLARE _done INT DEFAULT FALSE;
    DECLARE _tableName VARCHAR(255);
    DECLARE _cursor CURSOR FOR
        SELECT table_name 
        FROM information_schema.TABLES
        WHERE table_schema = SCHEMA();
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET _done = TRUE;

    OPEN _cursor;

    REPEAT FETCH _cursor INTO _tableName;

    IF NOT _done THEN
        SET @stmt_sql = CONCAT('DROP TABLE ', _tableName);
        PREPARE stmt1 FROM @stmt_sql;
        EXECUTE stmt1;
        DEALLOCATE PREPARE stmt1;
    END IF;

    UNTIL _done END REPEAT;

    CLOSE _cursor;

END$$

DELIMITER ;

call drop_all_tables(); 

DROP PROCEDURE IF EXISTS `drop_all_tables`;

从命令行中删除所有的表:

mysqldump -u [user_name] -p[password] -h [host_name] --add-drop-table --no-data [database_name] | grep ^DROP | mysql -u [user_name] -p[password] -h [host_name] [database_name]

其中[user_name]、[password]、[host_name]和[database_name]需要替换为真实的数据(用户、密码、主机名、数据库名)。

我发现生成的drop语句集很有用，并推荐以下调整:

将生成的drop限制在数据库中，如下所示:

SELECT concat('DROP TABLE IF EXISTS `', table_name, '`;')
FROM information_schema.tables
WHERE table_schema = 'MyDatabaseName';

注1:这并不执行DROP语句，它只是给你一个它们的列表。您需要将输出剪切并粘贴到SQL引擎中才能执行它们。

注2:如果你有视图，你必须手动将每个DROP TABLE ' VIEW_NAME '语句修改为DROP VIEW ' VIEW_NAME '。

注意，根据http://dev.mysql.com/doc/refman/5.5/en/drop-table.html，级联掉落是毫无意义的/误导性的:

允许RESTRICT和CASCADE使移植更容易。在MySQL 5.5中，它们什么都不做。”

因此，为了让drop语句工作，如果你需要:

SET FOREIGN_KEY_CHECKS = 0

这将禁用参考完整性检查-所以当你完成执行你需要的下降，你会想要重置键检查

SET FOREIGN_KEY_CHECKS = 1

最终的执行应该是这样的:

SET FOREIGN_KEY_CHECKS = 0;
-- Your semicolon separated list of DROP statements here
SET FOREIGN_KEY_CHECKS = 1;

注意:要使用SELECT输出更容易，mysql -B选项可以帮助。

上面的每个方法都包含了比这个AFAICT更多的工作…

( mysqldump --add-drop-table --no-data -u root -p database | grep 'DROP TABLE' ) > ./drop_all_tables.sql
mysql -u root -p database < ./drop_all_tables.sql
