Struct DeleteMany

pub struct DeleteMany<E>
where
    E: EntityTrait,
{ /* private fields */ }

Perform a delete operation on multiple models

Implementations

impl<'a, E> DeleteMany<E>

where E: EntityTrait,

pub fn exec<C>( self, db: &'a C, ) -> impl Future<Output = Result<DeleteResult, DbErr>> + 'a

where C: ConnectionTrait,

Execute a DELETE operation on many ActiveModels

pub fn exec_with_returning<C>( self, db: &C, ) -> impl Future<Output = Result<Vec<<E as EntityTrait>::Model>, DbErr>>

where E: EntityTrait, C: ConnectionTrait,

Execute an delete operation and return the deleted model

Panics

Panics if the database backend does not support DELETE RETURNING
