This isn't the sort of thing that Django can document easily (and I certainly can't recall it ever being mentioned in the Django docs). The problem is that is isn't as simple as 'the SQL statement you need to run' - every database does it quite differently. > Working with django for some weeks now, I find it quite common to want > to add or modify a column after the db is synced and some (valuable) > data is put in. > Since it will propably take some time that the three great migration > apps will merge(?) somehow and find their way into trunk (at least > that's the way I understood it when watching the video from django > con...), > I dicided to do migration by hand. Merging Django Evolution, South and dmigrations is certainly something that the three of us have discussed. We hope to be able to make some public announcements about this in the near future. In the meantime, any of the three migration projects are usable as-is. > I don't know SQL, and I find it quite hard to search for documentation > (although there is good documentation about SQL out there...), think > about migration strategies and tinker with differences between sqlite3 > and mysql. > So is there anywhere a short explanation of SQL from a django point of > view out there? Your best source of documentation will be the SQL manual for your database of choice, and/or the tutorials around the web for the same. There's almost nothing Django specific about migrations at the SQL level, other than knowing what you need your database to look like at the end of the process (which you can find out using ./manage sqlall).
