Any error message that you get that has "Database Vendor Code" in it is passing back the error code from the database. To determine what the issue is, do a Google search for that error code for your database type to determine what the issue is and how to fix it.
"Table/View/Synonym not found" means that whatever you're trying to use from the database either does not exist or the user Id that you're using to connect to the database doesn't have access to connect to it.
