Question

in below two sql query sql1 not selecting any row, and sql2 selecting only 1 for 111@k2.com

 var ids="'111@k2.com','222@k2.com','333@k2.com','444@k2.com','555@k2.com','666@k2.com'"

    val sql1 = SQL("SELECT id,point,privacy FROM `pointTable` WHERE state=1 and  id in ({users})").on("users" -> ids)
    sql1().map { row =>
      val point = if (row[Boolean]("privacy")) { row[Double]("point").toString } else { "0" }
      println(write(Map("id" -> row[String]("id"), "point" -> point)))
    }

    val sql2 = SQL("SELECT id,point,privacy FROM `pointTable` WHERE state=1 and  id in (" + ids + ")")
    sql2().map { row =>
      val point = if (row[Boolean]("privacy")) { row[Double]("point").toString } else { "0" }
      println(write(Map("id" -> row[String]("id"), "point" -> point)))
    }

in phpmyadmin when i run this query manualy it returns 6 rows then why not working perfectly here. i am using play framework 2.2 with scala 2.1

That's not going to work. Passing users though on is going to escape the entire string, so it's going to appear as one value instead of a list. Anorm in Play 2.3 actually allows you to pass lists as parameters, but here you'll have to work around that.

val ids: List[String] =  List("111@k2.com", "222@k2.com", "333@k2.com")
val indexedIds: List[(String, Int)] = ids.zipWithIndex

// Create a bunch of parameter tokens for the IN clause.. {id_0}, {id_1}, ..
val tokens: String = indexedIds.map{ case (id, index) => s"{id_${index}}" }.mkString(", ")

// Create the parameter bindings for the tokens
val parameters = indexedIds.map{ case (id, index) => (s"id_${index}" -> toParameterValue(id)) }

val sql1 = SQL(s"SELECT id,point,privacy FROM `pointTable` WHERE state=1 and  id in (${tokens})")
    .on(parameters: _ *)
