ScalikeJDBC
Just write SQL and get things done!
ScalikeJDBC is a tidy SQL-based DB access library for Scala that naturally wraps JDBC and provides easy-to-use APIs.
ScalikeJDBC is practical and production-ready. Use this library for your real projects.

Getting Started
Just add ScalikeJDBC, a JDBC driver, and an slf4j implementation to your sbt build settings:
libraryDependencies ++= Seq(
"org.scalikejdbc" %% "scalikejdbc" % "3.5.+",
"com.h2database" % "h2" % "1.4.+",
"ch.qos.logback" % "logback-classic" % "1.2.+"
)
If you're a Play2 user, take a look at play-support project, too:
https://github.com/scalikejdbc/scalikejdbc-play-support
First example
After adding the above dependencies to your build.sbt
, run sbt console
and execute the following code:
import scalikejdbc._
// initialize JDBC driver & connection pool
Class.forName("org.h2.Driver")
ConnectionPool.singleton("jdbc:h2:mem:hello", "user", "pass")
// ad-hoc session provider on the REPL
implicit val session = AutoSession
// table creation, you can run DDL by using #execute as same as JDBC
sql"""
create table members (
id serial not null primary key,
name varchar(64),
created_at timestamp not null
)
""".execute.apply()
// insert initial data
Seq("Alice", "Bob", "Chris") foreach { name =>
sql"insert into members (name, created_at) values (${name}, current_timestamp)".update.apply()
}
// for now, retrieves all data as Map value
val entities: List[Map[String, Any]] = sql"select * from members".map(_.toMap).list.apply()
// defines entity object and extractor
import java.time._
case class Member(id: Long, name: Option[String], createdAt: ZonedDateTime)
object Member extends SQLSyntaxSupport[Member] {
override val tableName = "members"
def apply(rs: WrappedResultSet) = new Member(
rs.long("id"), rs.stringOpt("name"), rs.zonedDateTime("created_at"))
}
// find all members
val members: List[Member] = sql"select * from members".map(rs => Member(rs)).list.apply()
// use paste mode (:paste) on the Scala REPL
val m = Member.syntax("m")
val name = "Alice"
val alice: Option[Member] = withSQL {
select.from(Member as m).where.eq(m.name, name)
}.map(rs => Member(rs)).single.apply()
