Dear all,

http://www.sqlobject.org/SQLObject.html#runtime-column-and-join-changes
claims that "SQLite does not support this feature".  However for the simple
case I have tried it works just as well on sqlite as postgres (see code
below).

Also, http://www.sqlobject.org/News.html#id25 claims that "Implemented
addColumn() for SQLite."

This is all inconsistent.  What's the true state of addColumn and delColumn
on sqlite?

Tom



% cat changi.py
from sqlobject import *
import sys

if len(sys.argv) > 1 and sys.argv[1] == 'sqlite':
        sqlhub.processConnection = connectionForURI('sqlite:/:memory:')
else:
        sqlhub.processConnection = 
connectionForURI('postgres:///var/run/postgresql/changi')

class Person(SQLObject):
        pass

Person.createTable()

Person()

print list(Person.select())

Person.sqlmeta.addColumn(StringCol('name'), changeSchema=True)

Person(name='Tom')

print list(Person.select())

Person.sqlmeta.delColumn('name', changeSchema=True)

Person()

print list(Person.select())
% python changi.py sqlite
[<Person 1 >]
[<Person 1 name=None>, <Person 2 name='Tom'>]
[<Person 1 >, <Person 2 >, <Person 3 >]
% python changi.py 
[<Person 1L >]
[<Person 1L name=None>, <Person 2L name='Tom'>]
[<Person 1L >, <Person 2L >, <Person 3L >]
