问题
Is it possible to import a single database from an --all-databases mysqldump? I guess I can modify the file manually but wondering if there are any command line options to do this.
I am moving servers and have a lot of databases, most of which I don't currently need or want at the moment but would like to have the option to restore a single one if need be.
回答1:
mysqldump output is just a set of SQL statements.
You can provide the desired database in the command line and skip the commands against the other databases using:
mysql -D mydatabase -o mydatabase < dump.sql
This will only execute the commands when mydatabase is in use
回答2:
You can use the following command:
mysql -u root -p --one-database destdbname < alldatabases.sql
Where destdbname is your desired database which you want to restore.
Another option which is IMHO much safer, is to extract the DB from an --all-databases dump. Example:
sed -n '/^-- Current Database: `dbname`/,/^-- Current Database: `/p' alldatabases.sql > output.sql
Replace dbname with the desired database name. alldatabases.sql is the name of your sql-dump file. That way you'll have the seperated DB on file, and then you can restore using a simple mysql command.
Good luck
