Extracting a Database From a mysqldump File

April 16, 2009 · Posted in MySQL · 6 Comments 

Restoring a single database from a full dump is pretty easy, using the mysql command line client’s --one-database option:

mysql> mysql -u root -p --one-database db_to_restore < fulldump.sql

But what if you don’t want to restore the database, you just want to extract it out of the dump file? Well, that happens to be easy as well, thanks to the magic of sed:

shell> sed -n '/^-- Current Database: `test`/,/^-- Current Database: `/p' fulldump.sql > test.sql

You just need to change “test” to be the name of the database you want extracted.
