之后,我们就可以直接使用 sqlx::query_as 并将该变量分类为 struct 的向量,借此实现预期功能,如下所示: // src/backend/router.rs pub async fn view_records(State(state): State<AppState>) -> Json<Vec<Note>> { let notes: Vec<Note> = sqlx::query_as("SELECT * FROM notes ") .fetch_all(&s...
pub description: String, pub price: usize,}struct Repository;impl Repository {pub(crate) fn new() -> Repository { Repository}pub(crate) async fn list(&self, mut db: Connection<Goods>) -> Vec<Good> { sqlx::query_as::<Postgres, Good>("SELECT id, name, description, price FROM goo...
可以像这样声明和使用状态：use sqlx::PgPool;#[derive(Clone)]struct AppState {db: PgPool}#[get("/")]async fn index(data: web::Data<AppState>) -> String {let res = sqlx::query("SELECT 'Hello Chongchong!'").fetch_all(&data.db).await.unwrap();format!("{res}")}然后,可以这样实现它...
SeaORM 的 src 目录下还有关于 database/ driver/ query/ executor 等模块,主要负责底层数据库交互了,这些功能主要基于 sqlx 和SeaQuery 构建。 SeaQuery SeaQuery是一个查询生成器,是 SeaORM的基础,用来在Rust中构建动态SQL查询,使用一个符合人体工程学的 API 将表达式、查询和模式构建为抽象语法树(AST)。在同...
The `sqlx::query*()` family of functions, as well as the `sqlx::query*!()` macros, will always prefer prepared statements. This was an explicit goal from day one.SQLx will **never** substitute query parameters for values on the client-side, it will always let the database server han...
