I would like to try and get the Rowversion change snuck into the schedule sometime soon.

An overview of this plan:
If we use the following command we can add a rowversion column to every table in both our main and settings databases.
EXEC sp_MSforeachtable '
if not exists (select * from sys.columns
where object_id = object_id(''?'')
and name = ''RowVersion'')
begin
ALTER TABLE ? ADD [RowVersion] Rowversion NOT NULL;
end';

With the rowversion column in place we can quickly check that data we are about to update is not stale, without having to read entire row into memory.
This is targeted more at disconnected/web service application contexts.
Entity Framework can be configured to take advantage of the column as well.

The plan was to add a one-time entry into the each of the update scripts to initialize this on all of the tables. And then add code to always run this command after main data or setting data updates are triggered (actually do something).


Any tips or best way to implement this???
