Postgresql 如何将普通PostgresSQL查询转换为平滑查询？

映射表

Table: person

从地址->城市='芝加哥'的人员中选择*

请帮助我将上述简单查询转换为流畅查询。

我正在使用下面的技术堆栈及其版本

• 斯卡拉：2.11.11
• 滑头：3.2.0
• 光滑pg:0.15.4

看看slick pg中的HStore功能：或者你可以看看你有没有尝试过？

case class Person(id: Int, name: String, address: Option[Map[String, String]])


trait ReceiptRepositoryImpl {
  self: PersonTable with SlickDBComponent =>

  def getPersonByCity(city: String): List[Person] = {
    personQuery.filter(_.address) // *Here i am unable to convert slick query of select * from person where address -> 'city' = 'Chicago'*
  }

}


   

 trait PersonTable {
    
      this: SlickDBComponent =>
    
      import driver.api._
    
      val personQuery: TableQuery[PersonDetailsTable] = TableQuery[PersonDetailsTable]
    
      class PersonDetailsTable(tag: Tag) extends Table[Person](tag, "person") {
        def id: Rep[Long] = column[Long]("id", O.PrimaryKey, O.AutoInc)
    
        def name: Rep[String] = column[String]("name")
    
        def address: Rep[Option[Map[String, String]]] = column[Option[Map[String, String]]]("address")
    
        def * = (id, name, address) <> (Person.tupled, Person.unapply)
      }
    
    }

 id |  name   |      address       
----+---------+--------------------
  1 | James   | "city"=>"Chicago"
  1 | Michael | "city"=>"New York"
