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

DB="your database name" \
    && mysql $DB < "SET FOREIGN_KEY_CHECKS=0" \
    && mysqldump --add-drop-table --no-data $DB | grep 'DROP TABLE' | grep -Ev "^$" | mysql $DB \
    && mysql $DB < "SET FOREIGN_KEY_CHECKS=1"

所有人都给出了很好的答案，但是，我为熟悉电子表格/excel表格的用户提供了另一种选择。根据第一个解决方案，我们得到了一个命令列表，但我们仍然需要截断第一个和最后一个字符('|')

使用“show tables;”查询，您将获得所有表的列表; 现在复制结果并粘贴到excel表格中(假设所有记录都在excel的“A”列中) 首先，你需要删除第一个和最后一个'|'符号函数来删除第一个字符ie。“|” =正确(A1, LEN (A1) 1)

函数删除最后一个字符。'|'并添加一个结尾分号

=CONCAT(LEFT(B1,LEN(B1)-1),";")

现在使用CONCAT函数创建最终的查询列表 =CONCAT("drop table "，C1)

简单明了(可能)。

也许不是一个很好的解决方案，但这对我很有效，帮了我大忙。

我遵循的步骤:

 1. generate drop query using concat and group_concat.
 2. use database
 3. disable key constraint check
 4. copy the query generated from step 1
 5. enable key constraint check
 6. run show table

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

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 ;
