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

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

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;

    UNTIL _done END REPEAT;

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$$

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。
