§Integrating with other database libraries

You can use any SQL database access library you like with Play, and easily retrieve either a Connection or a Datasource from the play.api.db.DB helper.

§Integrating with ScalaQuery

From here you can integrate any JDBC access layer that needs a JDBC data source. For example, to integrate with ScalaQuery:

import play.api.db._
import play.api.Play.current

import org.scalaquery.ql._
import org.scalaquery.ql.TypeMapper._
import org.scalaquery.ql.extended.{ExtendedTable => Table}

import org.scalaquery.ql.extended.H2Driver.Implicit._ 

import org.scalaquery.session._

object Task extends Table[(Long, String, Date, Boolean)]("tasks") {
    
  lazy val database = Database.forDataSource(DB.getDataSource())
  
  def id = column[Long]("id", O PrimaryKey, O AutoInc)
  def name = column[String]("name", O NotNull)
  def dueDate = column[Date]("due_date")
  def done = column[Boolean]("done")
  def * = id ~ name ~ dueDate ~ done
  
  def findAll = database.withSession { implicit db:Session =>
      (for(t <- this) yield t.id ~ t.name).list
  }
  
}

§Exposing the datasource through JNDI

Some libraries expect to retrieve the Datasource reference from JNDI. You can expose any Play managed datasource via JNDI by adding this configuration in conf/application.conf:

db.default.driver=org.h2.Driver
db.default.url="jdbc:h2:mem:play"
db.default.jndiName=DefaultDS
