### Breaking Changes
* Refactor `paginate()` & `count()` utilities into `PaginatorTrait`. You can use the paginator as usual but you might need to import `PaginatorTrait` manually when upgrading from previous version.
```rust
use futures::TryStreamExt;
use sea_orm::{entity::*, query::*, tests_cfg::cake};
let mut cake_stream = cake::Entity::find()
.order_by_asc(cake::Column::Id)
.paginate(db, 50)
.into_stream();
while let Some(cakes) = cake_stream.try_next().await? {
// Do something on cakes: Vec<cake::Model>
}
```
* The helper struct `Schema` converting `EntityTrait` into different `sea-query` statement now has to be initialized with `DbBackend`.
```rust
use sea_orm::{tests_cfg::*, DbBackend, Schema};
use sea_orm::sea_query::TableCreateStatement;
// Before `0.4.x`
let _: TableCreateStatement = Schema::create_table_from_entity(cake::Entity);
// Now
let schema: Schema = Schema::new(DbBackend::MySql);
let _: TableCreateStatement = schema.create_table_from_entity(cake::Entity);
```
* When performing insert or update operation on `ActiveModel` against PostgreSQL, RETURNING clause will be used to avoid excessive querying of inserted or updated model from the database.
```rust
// For PostgreSQL
cake::ActiveModel {
name: Set("Apple Pie".to_owned()),
..Default::default()
}
.insert(&postgres_db)
.await?;
assert_eq!(
postgres_db.into_transaction_log(),
vec![Transaction::from_sql_and_values(
DbBackend::Postgres,
r#"INSERT INTO "cake" ("name") VALUES ($1) RETURNING "id", "name""#,
vec!["Apple Pie".into()]
)]);
```
```rust
// For MySQL & SQLite
cake::ActiveModel {
name: Set("Apple Pie".to_owned()),
..Default::default()
}
.insert(&other_db)
.await?;
assert_eq!(
other_db.into_transaction_log(),
vec![
Transaction::from_sql_and_values(
DbBackend::MySql,
r#"INSERT INTO `cake` (`name`) VALUES (?)"#,
vec!["Apple Pie".into()]
),
Transaction::from_sql_and_values(
DbBackend::MySql,
r#"SELECT `cake`.`id`, `cake`.`name` FROM `cake` WHERE `cake`.`id` = ? LIMIT ?"#,
vec![15.into(), 1u64.into()]
)]);
```
