The DeriveRelatedEntity derive macro will implement `seaography::RelationBuilder` for `RelatedEntity` enumeration when the `seaography` feature is enabled
* Add `expr`, `exprs` and `expr_as` methods to `QuerySelect` trait https://github.com/SeaQL/sea-orm/pull/1702
```rust
use sea_orm::sea_query::Expr;
use sea_orm::{entity::*, tests_cfg::cake, DbBackend, QuerySelect, QueryTrait};
assert_eq!(
cake::Entity::find()
.select_only()
.expr(Expr::col((cake::Entity, cake::Column::Id)))
.build(DbBackend::MySql)
.to_string(),
"SELECT `cake`.`id` FROM `cake`"
);
assert_eq!(
cake::Entity::find()
.select_only()
.exprs([
Expr::col((cake::Entity, cake::Column::Id)),
Expr::col((cake::Entity, cake::Column::Name)),
])
.build(DbBackend::MySql)
.to_string(),
"SELECT `cake`.`id`, `cake`.`name` FROM `cake`"
);
assert_eq!(
cake::Entity::find()
.expr_as(
Func::upper(Expr::col((cake::Entity, cake::Column::Name))),
"name_upper"
)
.build(DbBackend::MySql)
.to_string(),
"SELECT `cake`.`id`, `cake`.`name`, UPPER(`cake`.`name`) AS `name_upper` FROM `cake`"
);
```
* Add `DbErr::sql_err()` method to convert error into common database errors `SqlErr`, such as unique constraint or foreign key violation errors. https://github.com/SeaQL/sea-orm/pull/1707
```rust
assert!(matches!(
cake
.into_active_model()
.insert(db)
.await
cake.into_active_model().insert(db).await
.expect_err("Insert a row with duplicated primary key")
.sql_err(),
Some(SqlErr::UniqueConstraintViolation(_))
));
assert!(matches!(
fk_cake
.insert(db)
.await
fk_cake.insert(db).await
.expect_err("Insert a row with invalid foreign key")
.sql_err(),
Some(SqlErr::ForeignKeyConstraintViolation(_))
