SQL statement joining Oracle and MS SQL Server

Question

I never seen this, but is it possible to have one SQL call join data from Oracle and SQl Server?

Answer 1

Yes- both Oracle and SQL Server support the linked server concept. That allows you to reference the other server using a 4 part name. For example:

select  *
from    LocalDb.Schema.Table
cross join
        OracleLinkedServer.RemoteDb.RemoteSchema.RemoteTable
