Struct sea_orm::query::UpdateMany

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

Defines an UPDATE operation on multiple ActiveModels

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::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) -> Selfwhere A: ActiveModelTrait<Entity = E>,

Add the models to update to Self

pub fn col_expr<T>(self, col: T, expr: SimpleExpr) -> Selfwhere T: IntoIden,

Creates a SimpleExpr from a column
