Limitations

This topic describes limitations for cross-database queries in Amazon Redshift.

When you work with the cross-database query feature in Amazon Redshift, be aware of the limitations following:

  • When you query database objects on any other unconnected databases, you have read access only to those database objects.

  • You can't query views that are created on other databases that refer to objects of yet another database.

  • You can only create late-binding and materialized views on objects of other databases in the cluster. You can't create regular views on objects of other databases in the cluster.

  • Amazon Redshift doesn't support tables with column-level privileges for cross-database queries.

  • Running cross-database queries on tables with interleaved sort keys isn't supported.
