slick

问题 I'm using Scala 2.10 and have problems with Slick (plain queries, java.sql.ResultSet). If I write queries like Q.query[String, ResultSet](query).list(rs.getString("id")) eclipse will tell me could not find implicit value for parameter rconv: scala.slick.jdbc.GetResult[java.sql.ResultSet] My most important source for this issue ( http://slick.typesafe.com/doc/0.11.2/sql.html ) does not help. How do I write these implicit conversions? And is there any other, familar way of representing

问题 I have the following coupled-to-model DAO implementation and to persist a new entity in the database I do (note the extra steps to be able to fetch the serially generated id) and this compiles fine (not actually tested yet): // this is generated by the Slick codegen case class UserRow(id: Long, ... class User(_tableTag: Tag) extends Table[UserRow](_tableTag, "user") lazy val User = new TableQuery(tag => new User(tag)) // function to persist a new user def create(user: UserRow): Future[UserRow

问题 I'm trying to template-out a TableQuery member but the path dependant types are messing me up. I've got a typical code-generated table like so: trait TablesContainer { case class MembersRow(firstName:String, lastName:String) class Members(_tableTag: Tag) extends Table[MembersRow](_tableTag, Some("dbo"), "MEMBERS") { def * = (firstName, lastName) <> (MembersRow.tupled, MembersRow.unapply) val firstName: Rep[String] = column[String]("FIRM_NAME") val lastName: Rep[String] = column[String]("LAST

问题 I am working in a project with scala play 2 framework where i am using slick as FRM and postgres database. In my project customer is an entity.

问题 I use slick 2.0 rc I have defined field UserId: case class UserId(id: Long) extends AnyVal with BaseId object UserId extends IdCompanion[UserId] when I use it: class Resources(tag: Tag) extends Table[Resource](tag, "RESOURCE") { def id = column[Long]("ID", O.PrimaryKey, O.AutoInc) def owner = column[UserId]("Owner") def types = column[String]("Type") def withuser = foreignKey("User_FK", owner, Users)(_.id) it give me compile error as: [error] C:\assigment\slick-advanced\app\models\Resource

问题 this is my code: import org.newdawn.slick.*; import org.newdawn.slick.state.*; public class Game extends StateBasedGame{ public static final String gamename = "Ham Blaster!"; public static final int menu = 0; public static final int play = 1; public Game(String gamename) { super(gamename); this.addState(new Menu(menu)); this.addState(new Play(play)); } public void initStatesList(GameContainer gc) throws SlickException{ this.getState(menu).init(gc, this); this.getState(play).init(gc, this);

问题 My scenario is as below: There are 3 tables (user, security, password) in my PG DB. When the end use tries to register self into my database, the code will check if the use exists in the user table. If exists, just return a None. otherwise, insert records into (user, security, password) within the same transaction. The following is my code: def selectUserCountQuery1(user: User): DBIO[Int] = { sql"""SELECT COUNT(user_id) FROM users WHERE provider_id = ${user.providerId} AND phone_num = ${user

问题 Is there any way to create a temp table from a select statement in Slick without using a plain sql query? I looked through the docs and was unable to find how to create a temp table, so I'm not sure if it's possible. 回答1: It appears that this is not supported yet. Slick's github shows it as an open issue: https://github.com/slick/slick/issues/799 来源： https://stackoverflow.com/questions/29981529/how-to-create-temp-table-as-select-in-slick

问题 I am using slick 2.0.1 (and can upgrade if required) and I want to retrieve the auto incrementing value from the database (postgresql). I have seen a few questions on SO on this already, but they are fairly old and I was hoping there was a better way than to do what this answer suggests: Scala & Play! & Slick & PostgreSQL auto increment def autoInc = name ~ price ~ description returning id def add(product: Product)(implicit s:Session): Long = { Products.autoInc.insert(p.name, p.price, p
