Expand description

CREATE VIEW name (columns) AS query.

The body is kept twice over, as a bound reference into this same arena and as the text that was written. Both are needed and they are needed for different things. The reference is what binds the body at creation, which is where a view over a table that is not there is refused. The text is what the catalog keeps, because a view is bound again at every reference rather than frozen at creation: a view over SELECT * FROM t follows t when a column is added to it, which was measured, and the only way to follow it is to have the query to bind again.

Fields§

§name: Slice

The view name, as a run of Slice parts, outermost first.

§columns: Slice

The column aliases, as a run of parts, empty when the statement wrote no list.

§query: QueryRef

The body.

§sql: StrRef

The body as it was written, which is what the catalog keeps.

§if_not_exists: bool

Whether IF NOT EXISTS was written.

§or_replace: bool

Whether OR REPLACE was written.

§temporary: bool

Whether TEMP or TEMPORARY was written.
