Trait diesel::query_builder::Query[][src]

pub trait Query {
    type SqlType;
Expand description

A complete SQL query with a return type.

This can be a select statement, or a command such as update or insert with a RETURNING clause. Unlike Expression, types implementing this trait are guaranteed to be executable on their own.

A type which doesn’t implement this trait may still represent a complete SQL query. For example, an INSERT statement without a RETURNING clause will not implement this trait, but can still be executed.

Associated Types

The SQL type that this query represents.

This is the SQL type of the SELECT clause for select statements, and the SQL type of the RETURNING clause for insert, update, or delete statements.
