Implementations

impl<A> Insert<A>where A: ActiveModelTrait,

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

Execute an insert operation

pub fn exec_without_returning<'a, C>( self, db: &'a C ) -> impl Future<Output = Result<u64, DbErr>> + 'awhere <<A as ActiveModelTrait>::Entity as EntityTrait>::Model: IntoActiveModel<A>, C: ConnectionTrait, A: 'a,

Execute an insert operation without returning (don’t use RETURNING syntax) Number of rows affected is returned

pub fn exec_with_returning<'a, C>( self, db: &'a C ) -> impl Future<Output = Result<<<A as ActiveModelTrait>::Entity as EntityTrait>::Model, DbErr>> + 'awhere <<A as ActiveModelTrait>::Entity as EntityTrait>::Model: IntoActiveModel<A>, C: ConnectionTrait, A: 'a,

Execute an insert operation and return the inserted model (use RETURNING syntax if database supported)

impl<A> Insert<A>where A: ActiveModelTrait,

pub fn one<M>(m: M) -> Insert<A>where M: IntoActiveModel<A>,

Insert one Model or ActiveModel

Model

use sea_orm::{entity::*, query::*, tests_cfg::cake, DbBackend};

pub fn many<M, I>(models: I) -> Insert<A>where M: IntoActiveModel<A>, I: IntoIterator<Item = M>,

Insert many Model or ActiveModel

use sea_orm::{entity::*, query::*, tests_cfg::cake, DbBackend};

);

pub fn add<M>(self, m: M) -> Insert<A>where M: IntoActiveModel<A>,

Add a Model to Self

Panics

Panics if the column value has discrepancy across rows

pub fn add_many<M, I>(self, models: I) -> Insert<A>where M: IntoActiveModel<A>, I: IntoIterator<Item = M>,

Add many Models to Self

pub fn on_conflict(self, on_conflict: OnConflict) -> Insert<A>

On conflict

on conflict do nothing

use sea_orm::{entity::*, query::*, sea_query::OnConflict, tests_cfg::cake, DbBackend};

let orange = cake::ActiveModel {
    id: ActiveValue::set(2),
    name: ActiveValue::set("Orange".to_owned()),

        .on_conflict(
            OnConflict::column(cake::Column::Name)
                .do_nothing()

        .to_string(),
    r#"INSERT INTO "cake" ("id", "name") VALUES (2, 'Orange') ON CONFLICT ("name") DO NOTHING"#,
);

on conflict do update

use sea_orm::{entity::*, query::*, sea_query::OnConflict, tests_cfg::cake, DbBackend};

let orange = cake::ActiveModel {
    id: ActiveValue::set(2),
    name: ActiveValue::set("Orange".to_owned()),

                .update_column(cake::Column::Name)
                .to_owned()
        )
        .build(DbBackend::Postgres)
        .to_string(),
