Struct ViewDescription 

pub struct ViewDescription {
    pub name: String,
    pub namespace_path: Vec<String>,
    pub query: String,
    pub default_database: String,
    pub default_namespace_path: Vec<String>,
    pub schema: SchemaRef,
}

What a database records about one view.

Returned by crate::connection::Connection::describe_view, and by create_view so a caller has the resolved schema without a second call.

Fields

name: String

The view’s name within its namespace.

namespace_path: Vec<String>

The namespace holding the view; empty is the root namespace.

query: String

The defining query, as the database stores it.

default_database: String

The database that unqualified table names in query resolve against. A view created from a session connected elsewhere can name a database other than its own, so this is part of what the query means rather than a restatement of where the view lives.

default_namespace_path: Vec<String>

The namespace path those unqualified names resolve against; empty is the root namespace.

Recorded with the view because it outlives the session that declared it: a reader that resolved the query against its own default namespace could read a different table than the view was defined over.

schema: SchemaRef

The schema the defining query resolved to when the view was created.
