Why? On huge databases the indexing will be slower but queries should not
be slower than systems not using uuid.
For a new application it's not a problem, but someone have an experience
about converting tables from standard ID to GUID?
Firstly: backup :)
I have done some conversions in the past. If I remember correctly, I added
an extra column (say 'uuid'), filled it with unique values, created foreign
Thanks Johann, Philip, really useful.
I'll use GUID.

Thats one of the reason I like starting database using database schema.
That way someone can use the XML and it works for any database domain. Just
some thoughts:-)

The id's stay same as in source database ---or--- web2py creates a mapping
based on db model and changes foreign keys with primary keys together?

export the whole database to csv and import it through web2py, the
integrity of the references will be preserved.
What for magic...?

Well it's always a shame to see that the answer was in the web2py book.
So shame on me, and thanks to all.
CSV all tables at once works perfectly.

And you can't store a record like that:
my_record = db.my_table(1)

As an alrenative. you can upload a csv file into web2py. Not a solution if
you want to do things dynamically and all the time. But you can use the csv

I'm sorry Willoughby but I don't understand your question.
With this csv export/import the problem is that id's change.
For example if you take a look to the auth_user table in my previous post,
table auth_membership will have wrong auth_user id's:
auth_membership.id
I was referring to the script from Alan Etkin in your first post.
It logs every step - what did the log steps say when you ran it?
