Transfer MySQL to SQLite

Question

I want to start using Core Date on iPhone with pre-existing MySQL databases. What's the easiest way to transfer a MySQL database to SQLite?

I've tried using SQLite Migrator, but I don't know where to find the ODBC drivers for Mac (Snow Leopard). I found http://www.ch-werner.de/sqliteodbc/ which seems to have drivers, but they are for Power PC.

If someone could give me a walkthrough, or tell me what the best tools for this are, I'd be grateful.

Thanks.

Answer 1

Have you looked at this Perl script? I haven't used it - just did a quick search for mysql to sqlite migration and it popped right up.

Edit (after you replied to my comment):

The reverse direction is dealt with here.

If you are going to do it repeatedly and if data structure changes are to happen, maybe you would be better off using something like Django (albeit in a very hackish way). With it I would:

# This three lines are done once
django-admin.py startproject mymigrationproject
cd mymigrationproject
./manage.py startapp migration

# The following lines you repeat each time you want to migrate the data
edit settings.py and make the changes to connect to MySQL
./manage.py inspectdb > ./migration/models.py
edit ./migration/models.py to reorder tables (tables in which other tables depend on top)
mkdir fixtures
./manage.py dumpdata migration > ./fixtures/data.json
edit settings.py and make the changes to connect to SQLite
./manage.py syncdb
./manage.py loaddata ./fixtures.data.json

You can use a trial from http://www.sqlmaestro.com/products/sqlite/datawizard/

It is completely functional for 30 days.

Answer 3

Perhaps the simplest would be to use mysqldump to dump the raw SQL from your MySQL database into a text file and then use the sqlite3_exec() function to execute that SQL in order to populate the SQLite database.

Answer 4

There is a free ETL product that can be used to migrate data from one db to another. Have a look: http://www.talend.com/index.php

Good luck!

Answer 5

You can get ODBC drivers for Mac OS X from Actual Technologies.

To connect to MySQL you need their ODBC Driver for Open Source Databases:
