So, is there no way i can version the stored procedures or tables.
Has anyone done anything similar.
Does any system table have a description or any field i could store the version for the tables/stored procedures/views.
thanks jim, but i think, If its just 20% tables changing and that two in a sub-schema storing person details for example, i might not want to have downtime on other applications that are not using person sub-system.
thanks in advance,
vish

The way I handle this is to version the entire schema and have scripts
that know how to upgrade from one version to another. If you think about
it, you really want/need everything in the database to be designed to
run together anyway. I've yet to find a case where I'd want some of the
stuff in the schema to be older than other stuff.
case where it makes sense to ha
