Trait Implementations

impl<DB, Q> Query for BoxedSqlQuery<'_, DB, Q>

where DB: Backend,

type SqlType = Untyped

The SQL type that this query represents.

impl<DB, Query> QueryFragment<DB> for BoxedSqlQuery<'_, DB, Query>

where DB: Backend + DieselReserveSpecialization, Query: QueryFragment<DB>,

fn walk_ast<'b>(&'b self, out: AstPass<'_, 'b, DB>) -> QueryResult<()>

Walk over this QueryFragment for all passes.

impl<DB: Backend, Query> QueryId for BoxedSqlQuery<'_, DB, Query>

const HAS_STATIC_QUERY_ID: bool = false

Can the SQL generated by Self be uniquely identified by its type?

type QueryId = ()

A type which uniquely represents Self in a SQL query.

fn query_id() -> Option<TypeId>

Returns the type id of Self::QueryId if Self::HAS_STATIC_QUERY_ID. Returns None otherwise.

impl<Conn: Connection, Query> RunQueryDsl<Conn> for BoxedSqlQuery<'_, Conn::Backend, Query>

fn execute(self, conn: &mut Conn) -> QueryResult<usize>

where Conn: Connection, Self: ExecuteDsl<Conn>,

Executes the given command, returning the number of rows affected.

fn load<'query, U>(self, conn: &mut Conn) -> QueryResult<Vec<U>>

where Self: LoadQuery<'query, Conn, U>,

Executes the given query, returning a Vec with the returned rows.

fn load_iter<'conn, 'query: 'conn, U, B>( self, conn: &'conn mut Conn, ) -> QueryResult<Self::RowIter<'conn>>

where U: 'conn, Self: LoadQuery<'query, Conn, U, B> + 'conn,

Executes the given query, returning an Iterator with the returned rows.

fn get_result<'query, U>(self, conn: &mut Conn) -> QueryResult<U>

where Self: LoadQuery<'query, Conn, U>,

Runs the command, and returns the affected row.

fn get_results<'query, U>(self, conn: &mut Conn) -> QueryResult<Vec<U>>

where Self: LoadQuery<'query, Conn, U>,

Runs the command, returning an Vec with the affected rows.
