Trait diesel::query_builder::SelectQuery

pub trait SelectQuery {
    type SqlType;
}

Indicates that a type is a SELECT statement.

This trait differs from Query in two ways:

• It is implemented only for select statements, rather than all queries which return a value.
• It has looser constraints. A type implementing SelectQuery is known to be potentially valid if used as a subselect, but it is not necessarily able to be executed.
