# It would be nice to be able to mix python into the upgrade script, rather than just SQL. For example, I recently dropped a column that had both an employee’s first and last name, and separated this into two columns. I used SQL to make the new columns, then I used python to read data out of the old single column and write it to the two new columns. Then I used SQL again to drop the old column.

Hi Craig, thanks for the tip. There's now a wiki page on the TG site that is based on this article, so feel free to add your notes over there. This is the page.

One thing that you might want to mention in this page somewhere is that all of the .sql files should be relative to the sql-history directory not the root of the application. It took me quite a while to figure that one out. Thanks for the info on this though.

Chris, I just created http://docs.turbogears.org/1.0/TgAdminSqlUpgrade with the text from this blog, and added a link to the 1.0/RoughDocs page. I saw the TgAdmin page, and maybe editors would want to consolidate mine into there, or at least add a link to this new page from there.

Hi Greg,

you are probably using SQLAlchemy for your model. The “tg-admin sql” tool is really only a wrapper around sqlobject-admin. Naturally this only works for SQLObject model. For SQLAlchemy, “tg-admin sql” is only a very basic substitute for this integrated into TurboGears, because SQLAlchemy does not provide such a tool as sqlobject-admin.

Feel free to file a feature request ticket for this on our Trac (http://trac.turbogears.org/newticket).

@Matt Why this isn’t more widely advertised? Because you didn’t put the info on the wiki yet! Honestly, if you want to turn this into a page on our doc wiki (see http://docs.turbogears.org/DocHelp), you’d be more than welcome! Just put it there in whatever form you see fit and I’ll see that I adapt it to our wiki docs standards.

Chris
