Question

I’m having trouble restoring from a dump file. The dump file has an option to build the database if it doesn’t exist. So why does the script below only works when I have the database.

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

Here’s the dump file

Please help. How do I restore the database if it has been dropped?

Answer 1

Your MySQL command line is attempting to choose a database, which will fail if the database doesn’t exist. You can omit that from your command line arguments as the SQL file is choosing a database itself with USE.

Try:

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