Connecting to the DB

val client = Client(host, username, password, database)

Selecting with simple query

val f = client.select("select * from users") {row =>
	User(row.getString("email"), row.getString("name"))
}
logger.debug("Responded " + f.get)

Selecting with prepared statement

val f = for {
	prep <- client.prepare("select * from users where email=$1 and name=$2")
	users <- prep.select("mickey@mouse.com", "Mickey Mouse") {
		row => User(row.getString("email"), row.getString("name"))
	}
} yield users
logger.debug("Responded " + f.get)

Inserting with prepared statement

val f = for {
	prep <- client.prepare("insert into users(email, name) values ($1, $2)")
	one <- prep.exec("Daisy Duck", "daisy@duck.com")
	two <- prep.exec("Minnie Mouse", "ms.mouse@mouse.com")
} yield one.affectedRows + two.affectedRows

logger.debug(f.get + " rows affected")

Updating with prepared statement

val f = for {
	prep <- client.prepare("update users set name=$1, email=$2 where email='mickey@mouse.com'")
	res <- prep.exec("Mr. Michael Mouse", "mr.mouse@mouse.com")
} yield res.affectedRows

logger.debug(f.get + " rows affected")
