I was looking for a feature in Ingre Vectorwise similar to ‘Linked Server’ in MS SQL Server and ‘Database Link’ in Oracle. But unfortunately it seems Ingre Vectorwise 2.5 does not offer anything similar.

 

The Ingres has ‘Register Table as Link’ (Ingres Star) which is currently not supported in Vectorwise. So I think the only available option as of today is to copy tables in one database on one server and then do the cross joins.

 

Another way would be to create linked servers in MS SQL Server to different instances/databases of Ingres Vectorwise, but this will be very inefficient solution. It may be ok for some manual data analysis.
