Schema name (your db_name) support in TS is a little sketchy. We’re trying to improve it, but it’s something that needed to be done correctly upfront and wasn’t.
I might suggest: Starting with db1.inventory and db1.inventory create database “common” and move all inventory into a common table: Insert into common.inventory select * db1.inventory union all select * db2.inventory Then drop db1./db2.inventory tables and add views of the same name that reference the common.inventory table. Assuming that your views are fully 2-way you shouldn’t have to change any code.

I forgot you can specify db_name.view_name. I assume you can specify db_name.table_name as well for READ, WRITE, INSERT, SELECT AND UPDATE assuming you have given Assigned Privileges for that USER to access that database. Also assuming that in TeraScript, I would specify the alternate database can under the Name in the Deployment Data Source within Data Source Selection for the Data Source action. I am also assuming that this is the “Default Database” and that if I was going to perform a JOIN that I would need to use a “Custom SQL Query” action in order to be able to designate the alternate db_name.table_name within the SQL of the custom query. Thanks for leading me in the right direction and commenting on this additional info.
