let dsn = "databend://root:@localhost:8000/default?sslmode=disable";
let conn = DatabendConnection::create(dsn).unwrap();

let sql_create = "CREATE TABLE books (

let (title,author,date): (String,String,i32) = row.try_into().unwrap();
println!("{} {} {}", title, author, date);

query iter

let mut rows = conn.query_iter("SELECT * FROM books;").await.unwrap();
while let Some(row) = rows.next().await {
    let (title,author,date): (String,String,chrono::NaiveDate) = row.unwrap().try_into().unwrap();
    println!("{} {} {}", title, author, date);
