First create the database, then just dump it over.

1 First, create a new database:

create database new_db;

2 Use the RENAME TABLE command to change the table name and move the table to the new database:

rename table old_db.tb to new_db.tb;

3 Delete the old database after completion:

drop database old_db;

You can only recreate the database. If the business cannot be stopped, try using DM binlog synchronization.

Yes, generally the method used is to rename the table.

In lower versions of MySQL, you can still rename the database, but in higher versions, you can’t. I guess TiDB doesn’t support it either, so it’s better to use the rename db.table syntax.

For versions above v6.4, you can use flashback database to change the database name.

It’s pretty good, but will there be any exceptions that can’t be recovered from…

| username: Jellybean | Original post link

Haha, this idea is very bold and also very risky.

Under normal circumstances, it is indeed feasible, but under abnormal circumstances, you might need to run away :sweat_smile:

I think it’s more reliable to dump it out and then import it again, at least there will be backup data.

| username: Jellybean | Original post link

Yes, I agree with your statement, it is stable and reliable.
