Load the database:

sqlite3 storage.db

Within the SQLite interface, export the database:

.output storage_db.sql
.dump
.output stdout
.exit

With the database exported, you should make a working copy of it instead of working directly on the storage_db.sql export; the source export should just be a clean backup. We’ll make a working copy of storage_db.sql and name it storage_db_CLEAN.sql like this:

cp storage_db.sql storage_db_CLEAN.sql

Now open up storage_db_CLEAN.sql and edit it as you see fit like this:

nano storage_db_CLEAN.sql

After your done editing the database, load it back into SQLite like this:

sqlite3 storage.db < storage_db_CLEAN.sql
