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`;

在像bash/zsh这样的Linux shell中:

DATABASE_TO_EMPTY="your_db_name";
{ echo "SET FOREIGN_KEY_CHECKS = 0;" ; \
  mysql "$DATABASE_TO_EMPTY" --skip-column-names -e \
  "SELECT concat('DROP TABLE IF EXISTS ', table_name, ';') \
   FROM information_schema.tables WHERE table_schema = '$DATABASE_TO_EMPTY';";\
  } | mysql "$DATABASE_TO_EMPTY"

这将生成命令，然后立即将它们输送到第二个客户端实例，该实例将删除表。

聪明的部分当然是从这里的其他答案复制的-我只是想要一个复制-粘贴的一行程序来实际完成OP想要的工作。

当然，你也必须在这些mysql命令中输入你的凭证(两次)，除非你有一个非常低的安全设置。(或者你可以用mysql命令的别名来包含你的学分。)

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`;

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。

基于@Dion Truter和@Wade Williams的回答，下面的shell脚本将删除所有表，首先显示它将要运行的内容，并让您有机会使用Ctrl-C中止。

#!/bin/bash

DB_HOST=xxx
DB_USERNAME=xxx
DB_PASSWORD=xxx
DB_NAME=xxx

CMD="mysql -sN -h ${DB_HOST} -u ${DB_USERNAME} -p${DB_PASSWORD} ${DB_NAME}"

# Generate the drop statements
TMPFILE=/tmp/drop-${RANDOM}.sql
echo 'SET FOREIGN_KEY_CHECKS = 0;' > ${TMPFILE}
${CMD} $@ >> ${TMPFILE} << ENDD
    SELECT concat('DROP TABLE IF EXISTS \`', table_name, '\`;')
    FROM information_schema.tables
    WHERE table_schema = '${DB_NAME}';
ENDD
echo 'SET FOREIGN_KEY_CHECKS = 1;' >> ${TMPFILE}

# Warn what we are about to do
echo
cat ${TMPFILE}
echo
echo "Press ENTER to proceed (or Ctrl-C to abort)."
read

# Run the SQL
echo "Dropping tables..."
${CMD} $@ < ${TMPFILE}
echo "Exit status is ${?}."
rm ${TMPFILE}
