May use `lazy_static` crate to define rbatis as a global variable because rbatis is thread safe let rb = Rbatis::new(); /// connect to database rb.link("mysql://root:123456@localhost:3306/test").await.unwrap(); /// customize connection pool parameters (optional) // let mut opt =...
letpool = MySqlPool::connect("mysql://user:pass@host/database").await?; Querying In SQL, queries can be separated into prepared (parameterized) or unprepared (simple). Prepared queries have their query plancached, use a binary mode of communication (lower bandwidth and faster decoding), and...
