pub struct UpdateMany<E>
where
    E: EntityTrait,
{
    pub(crate) query: UpdateStatement,
    pub(crate) entity: PhantomData<E>,
}

Implementations

impl<'a, E> UpdateMany<E>

where E: EntityTrait,

pub async fn exec<C>(self, db: &'a C) -> Result<UpdateResult, DbErr>

where C: ConnectionTrait,

Execute an update operation on multiple ActiveModels

pub async fn exec_with_returning<C>( self, db: &'a C, ) -> Result<Vec<<E as EntityTrait>::Model>, DbErr>

where C: ConnectionTrait,

Execute an update operation and return the updated model (use RETURNING syntax if supported)

Panics

Panics if the database backend does not support UPDATE RETURNING.

impl<E> UpdateMany<E>

where E: EntityTrait,

pub fn set<A>(self, model: A) -> UpdateMany<E>

where A: ActiveModelTrait<Entity = E>,

Add the models to update to Self

pub fn col_expr<T>(self, col: T, expr: SimpleExpr) -> UpdateMany<E>

where T: IntoIden,

Creates a SimpleExpr from a column
