[][src]Struct diesel::sql_types::Untyped

pub struct Untyped;

Query nodes with this expression type do not have a statically at compile time known expression type.

An example for such a query node in diesel itself, is sql_query as we do not know which fields are returned from such a query at compile time.

For loading values from queries returning a type of this expression, consider using [#[derive(QueryableByName)]] on the corresponding result type.
