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

下面是一种通过bash脚本自动做到这一点的方法:

host=$1
dbName=$2
user=$3
password=$4

if [ -z "$1" ]
then
    host="localhost"
fi

# drop all the tables in the database
for i in `mysql -h$host -u$user -p$password $dbName -e "show tables" | grep -v Tables_in` ; do  echo $i && mysql -h$host -u$user -p$password $dbName -e "SET FOREIGN_KEY_CHECKS = 0; drop table $i ; SET FOREIGN_KEY_CHECKS = 1" ; done

从http://www.devdaily.com/blog/post/mysql/drop-mysql-tables-in-any-order-foreign-keys:

SET FOREIGN_KEY_CHECKS = 0;
drop table if exists customers;
drop table if exists orders;
drop table if exists order_details;
SET FOREIGN_KEY_CHECKS = 1;

(注意，这回答了如何禁用外键检查，以便能够以任意顺序删除表。它没有回答如何为所有现有的表自动生成drop-table语句，并在一个脚本中执行它们。Jean的回答是。)

此解决方案基于@SkyLeach答案，但支持删除带外键的表。

echo "SET FOREIGN_KEY_CHECKS = 0;" > ./drop_all_tables.sql
mysqldump --add-drop-table --no-data -u user -p dbname | grep 'DROP TABLE' >> ./drop_all_tables.sql
echo "SET FOREIGN_KEY_CHECKS = 1;" >> ./drop_all_tables.sql
mysql -u user -p dbname < ./drop_all_tables.sql

从这个答案来看，

执行:

  use `dbName`; --your db name here
  SET FOREIGN_KEY_CHECKS = 0; 
  SET @tables = NULL;
  SET GROUP_CONCAT_MAX_LEN=32768;

  SELECT GROUP_CONCAT('`', table_schema, '`.`', table_name, '`') INTO @tables
  FROM   information_schema.tables 
  WHERE  table_schema = (SELECT DATABASE());
  SELECT IFNULL(@tables, '') INTO @tables;

  SET        @tables = CONCAT('DROP TABLE IF EXISTS ', @tables);
  PREPARE    stmt FROM @tables;
  EXECUTE    stmt;
  DEALLOCATE PREPARE stmt;
  SET        FOREIGN_KEY_CHECKS = 1;

这将从当前使用的数据库中删除表。您可以使用use设置当前数据库。

或者，Dion接受的答案更简单，只是需要执行两次，第一次获取查询，第二次执行查询。我提供了一些愚蠢的反勾来转义db和表名中的特殊字符。

  SELECT CONCAT('DROP TABLE IF EXISTS `', table_schema, '`.`', table_name, '`;')
  FROM   information_schema.tables
  WHERE  table_schema = 'dbName'; --your db name here

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`;
