+## Delete by Primary Key
+
+Instead of selecting `Model` from the database then deleting it. You could also delete a row from database directly by its primary key.
+
+```rust
+let res: DeleteResult = Fruit::delete_by_id(38).exec(db).await?;
+assert_eq!(res.rows_affected, 1);
+```
+
 ## Delete Many
 
 You can also delete multiple rows from the database without finding each `Model` with SeaORM select.
