Trait diesel::query_builder::SelectQuery
source · pub trait SelectQuery {
type SqlType;
}
Expand description
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.
