Question

我无法从转储文件恢复。转储文件有一个选项来构建数据库（如果它不存在）。那么为什么下面的脚本只有在我拥有数据库时才有效。

mysql -u root -p1234 modal_db＆lt; C：\瓦帕\ db_backups \ modal_db \ mdb.sql

这是转储文件

请帮忙。如果数据库被删除，如何恢复数据库？

Answer 1

您的MySQL命令行正在尝试选择数据库，如果数据库不存在，该数据库将失败。您可以从命令行参数中省略它，因为SQL文件正在使用USE选择数据库本身。

尝试：

mysql -u root -p1234 < c:\wamp\db_backups\modal_db\mdb.sql

从转储文件中恢复mysql数据库未知数据库错误
