How to vacuum sqlite database?

Question

I want to know how to vacuum sqlite database. I tried a syntax MANUAL VACUUM command for the whole database from command prompt:

 $sqlite3 database_name \"VACUU         


        

Answer 1

Give the command like this:

$sqlite3 database_name 'VACUUM;'

As a matter of fact, this is the way to do also other queries from command line:

$sqlite3 database_name 'select * from tablename;'

You can use the full path to the db:

$sqlite3 /path/to/db/foo.db 'VACUUM;'

Answer 2

You don't to specify the table name in the syntax. Only VACUUM works.

Also, it will clean the main database only and not any attached database files.

For more info, refer to the SQLite documentation.
