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

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`;

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`;

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

mysql -u user -p dbname < ./drop_all_tables.sql

只要在这里放上Jonathan Watt所做的一些有用的评论，就可以删除所有表格

MYSQL="mysql -h HOST -u USERNAME -pPASSWORD DB_NAME"
$MYSQL -BNe "show tables" | awk '{print "set foreign_key_checks=0; drop table `" $1 "`;"}' | $MYSQL
unset MYSQL

这对我有帮助，我希望它能有用

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)。
