在php中，它很简单:

$pdo = new PDO('mysql:dbname=YOURDB', 'root', 'root');

$pdo->exec('SET FOREIGN_KEY_CHECKS = 0');

$query = "SELECT concat('DROP TABLE IF EXISTS ', table_name, ';')
          FROM information_schema.tables
          WHERE table_schema = 'YOURDB'";

foreach($pdo->query($query) as $row) {
    $pdo->exec($row[0]);
}

$pdo->exec('SET FOREIGN_KEY_CHECKS = 1');

只需要记住将YOURDB更改为数据库的名称，当然还有user/pass。

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

在php中，它很简单:

$pdo = new PDO('mysql:dbname=YOURDB', 'root', 'root');

$pdo->exec('SET FOREIGN_KEY_CHECKS = 0');

$query = "SELECT concat('DROP TABLE IF EXISTS ', table_name, ';')
          FROM information_schema.tables
          WHERE table_schema = 'YOURDB'";

foreach($pdo->query($query) as $row) {
    $pdo->exec($row[0]);
}

$pdo->exec('SET FOREIGN_KEY_CHECKS = 1');

不从SQL复制返回值的一步解决方案选择使用过程的查询。

SET FOREIGN_KEY_CHECKS = 0;
SET SESSION group_concat_max_len = 1000000;

SET @TABLES = NULL;
SELECT GROUP_CONCAT('`', table_schema, '`.`', table_name,'`') INTO @TABLES FROM information_schema.tables 
  WHERE table_schema = 'databaseName';

SET @TABLES = CONCAT('DROP TABLE IF EXISTS ', @TABLES);

PREPARE stmt FROM @TABLES;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

SET SESSION group_concat_max_len = 1024;
SET FOREIGN_KEY_CHECKS = 1

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`;

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
