如果在linux(或任何其他支持管道、echo和grep的系统)中，你可以用一行代码完成:

echo "SET FOREIGN_KEY_CHECKS = 0;" > temp.txt; \
mysqldump -u[USER] -p[PASSWORD] --add-drop-table --no-data [DATABASE] | grep ^DROP >> temp.txt; \
echo "SET FOREIGN_KEY_CHECKS = 1;" >> temp.txt; \
mysql -u[USER] -p[PASSWORD] [DATABASE] < temp.txt;

我知道这是一个老问题，但我认为这个方法又快又简单。

我使用以下MSSQL服务器:

if (DB_NAME() = 'YOUR_DATABASE') 
begin
    while(exists(select 1 from INFORMATION_SCHEMA.TABLE_CONSTRAINTS where CONSTRAINT_TYPE='FOREIGN KEY'))
    begin
         declare @sql nvarchar(2000)
         SELECT TOP 1 @sql=('ALTER TABLE ' + TABLE_SCHEMA + '.[' + TABLE_NAME + '] DROP CONSTRAINT [' + CONSTRAINT_NAME + ']')
         FROM information_schema.table_constraints
         WHERE CONSTRAINT_TYPE = 'FOREIGN KEY'
         exec (@sql)
         PRINT @sql
    end

    while(exists(select 1 from INFORMATION_SCHEMA.TABLES))
    begin
         declare @sql2 nvarchar(2000)
         SELECT TOP 1 @sql2=('DROP TABLE ' + TABLE_SCHEMA + '.[' + TABLE_NAME + ']')
         FROM INFORMATION_SCHEMA.TABLES
        exec (@sql2)
        PRINT @sql2
    end
end
else
    print('Only run this script on the development server!!!!')

用数据库的名称替换YOUR_DATABASE或删除整个IF语句(我喜欢增加的安全性)。

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

只是一个温馨的提醒，

如果可能并且没有其他问题，您可以删除数据库并重新创建它。

删除数据库<database_name> 创建数据库<database_name>

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

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`;
