数据库连接

node 版本

目前仅支持 mysql

```rust use access_db::AccessMysql;

let myconn = AccessMysql::new(1, 50, "mysql://root:12345678@localhost:3306/devdb".tostring());

let id = myconn.run_one(myset!("feedback", { "content": "ADFaadf", "uid": 9, }));

myconn.run_one(mydel!("feedback", 50));

myconn.run_one(myupdate!("feedback", 56, { "content": "更新后的内容，一一一一" }));

let sql1 = myget!("feedback", 33, "id as id, feedback.content as cc");

[derive(Serialize, Deserialize, Debug)]

struct Feedback { id: u64, cc: String } let res_get: (Vec, Option<(u64, String)>) = myconn.run(sql1);

let sqlf = myfind!("feedback", { p0: ["uid", ">", 330], r: "p0", page: 2, limit: 5, select: "id, content as cc", }); let resfind: (Vec, Option<(u64, String)>) = myconn.run(sql_f);

let res_count: (Vec, Option) = myconn.run(mycount!("feedback", {}));
