Restoring a single database from a full dump is pretty easy, using the mysql command line client’s –one-database option:
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:
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. Or you can use this shell script:
Usage: sh MyDumpSplitter.sh DUMP-FILE-NAME — Extract all tables as a separate file from dump.
sh MyDumpSplitter.sh DUMP-FILE-NAME TABLE-NAME — Extract single table from dump.
sh MyDumpSplitter.sh DUMP-FILE-NAME -S TABLE-NAME-REGEXP – Extract tables from dump for specified regular expression.
