I'm needing to add a new schema to the schema collection on an existing table. Right now, I simply unbind the old schema collection from the table column, drop it, create the new schema, and rebind it to the table column.
The problem is, I need to preserve all of the data already in the table. What looks like is happening, is that when I apply the new schema, it goes through all of the data and revalidates everything which takes a really long time. Is there a better way to do this?
What I've tried so far is to rename the existing the table (e.g. Mytable_bak), then recreate the same table but with the new schema collection attached, select all of the data out of the _bak table into the newly created table, and then drop the _bak table. This is how I've done in the past and it seems to be a bit faster (not sure why). The problem with this is that it's really just a big pain. The table is actually published for replication which causes it to throw errors. I guess maybe if there was a way to temporarily disable replication for the table, make the migration, then re-replication, then that might work. But this is kind of out of my current knowledge.
So I'm wondering if there's a better way to achieve all of this, or maybe just a solution to my current approach?
