Views

A view is a virtual table derived from one or more underlying database tables or views in the source system. A view can be defined via a direct SQL query and allows you to produce custom slices of data.

Setup

The setup process is very similar to the process for Tables, except that you provide your own view alias and a SQL query to define the view's contents. The alias is how users will reference the view in queries — SELECT a, b, c FROM <your_view_alias> — and the SQL query will determine the schema and contents of the resulting relation.

SQL definitions

The SQL query will be executed directly against the source system, and should therefore be written in the source system's native dialect. Currently Subsalt only supports single-query views.

Immutability

Views are structurally immutable; you cannot modify the schema or reconfigure metadata once the view has been created. If you need to modify the structure of a view, you should delete and recreate it.
