Hello world:

```scala

// table rows

case class Customer(id: Int, name: String) derives SqlReadRow

case class Phone(id: Int, number: String) derives SqlReadRow

// joined row

case class CustomerWithPhone(c: Customer, p: Phone) derives SqlReadRow

val ds = JdbcDataSource()

ds.setURL("jdbc:h2:mem:")

val ctx = SqueryContext(ds)

ctx.run {

  val res: Seq[CustomerWithPhone] = sql"""

    SELECT c.id, c.name,

           p.id, p.number

    FROM customers c

    JOIN phones p ON p.customer_id = c.id

  """.readRows[CustomerWithPhone]()

}

```
