Examples

use co_orm::{Crud, FromRow};
 
#[derive(Debug, Crud, FromRow)]
#[co_orm(rename = "users")] // rename table name
pub struct User {
    // #[co_orm(id)] // default first field is primary key
    #[co_orm(seq)] // sequence field, insert will ignore this field
    pub id: u64,
    #[co_orm(rename = "name")] // rename field name
    #[co_orm(by)] // generate query_by_field,update_by_field,delete_by_field
    pub name: String,
    #[co_orm(update)] // generate method update_xxx. 
    pub password: String,
    #[co_orm(skip)] // ignore field
    pub addr: Option<String>,
}
 
// use crud
let u = User::get(&pool, 1).await;
println!("get {:?}", u);
let u = User::get_by(&pool, "where id=?", sql_args!(1)).await;
println!("get_by {:?}", u);
