问题描述
如何使用命令提示符删除Windows MySQL中的所有表？我想这样做的原因是我们的用户可以访问数据库删除，但没有访问重新创建数据库本身，因此我们必须手动删除表。有办法立刻删除所有的表吗？请记住，大多数表与外键链接，因此必须按特定顺序删除。
How do I drop all tables in Windows MySQL, using command prompt? The reason I want to do this is that our user has access to the database drops, but no access to re-creating the database itself, for this reason we must drop the tables manually. Is there a way to drop all the tables at once? Bear in mind that most of the tables are linked with foreign keys so they would have to be dropped in a specific order.
推荐答案
你可以这样生成语句： DROP TABLE t1，t2，t3，... 然后使用预备语句执行它：
You can generate statement like this: DROP TABLE t1, t2, t3, ... and then use prepared statements to execute it:
SET FOREIGN_KEY_CHECKS = 0;
SET @tables = NULL;
SELECT GROUP_CONCAT(table_schema, '.', table_name) INTO @tables
FROM information_schema.tables
WHERE table_schema = 'database_name'; -- specify DB name here.
SET @tables = CONCAT('DROP TABLE ', @tables);
PREPARE stmt FROM @tables;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
SET FOREIGN_KEY_CHECKS = 1;
