Struct EntityUpdateMany 

pub struct EntityUpdateMany<E: EntityTrait> { /* private fields */ }

A chainable wrapper around SeaORM’s UpdateMany<E> that returns rows_affected on execution.

Example

let affected = EntityUpdateMany::new(TodoEntity::update_many())
    .filter(todo::Column::Done.eq(false))
    .col_expr(todo::Column::Done, Expr::value(true))
    .exec(&db)
    .await?;

pub fn filter(self, f: impl IntoCondition) -> Self

Apply a WHERE condition.

pub fn col_expr<C: IntoIden>(self, col: C, expr: SimpleExpr) -> Self
