Question

我在PostgreSql中有一个架构，我想在update set字段中users_id执行：

CREATE TABLE if not exists rooms (
  oid char(24),
  owner_id char(24) not null,
  users_id text[],

  PRIMARY KEY (oid)
);

执行sql如下：

update rooms set users_id = (select array_agg(distinct e) from  
unnest(users_id || '{5a16f7ce77c8a2b22406fb86}') e) where  oid =  
'5a16f7ce77c8a2b22406fb86';

更新users_id数组并执行distinct操作。

在Quill中，我尝试使用该方法：

def addUserInRoom(userId: ObjectId, roomId: ObjectId): Unit = {
    val q = quote(
      (uid: String, rid: String) =>
        infix"""update rooms set users_id = (select array_agg(distinct e) from unnest(users_id || '{${uid}}') e) where  oid = '${rid}'""".as[Query[Long]]
    )

    run(q(lift(userId.toString), lift(roomId.toString)))
}

发生了异常：

Exception in thread "main" org.postgresql.util.PSQLException: The column index is out of range: 1, number of columns: 0.
    at org.postgresql.core.v3.SimpleParameterList.bind(SimpleParameterList.java:65)

    at io.getquill.context.jdbc.Encoders.$anonfun$stringEncoder$2$adapted(Encoders.scala:44)
...

如何使用scala Quill库执行sql？不同的方式总是欢迎！
感谢

依赖是：

  "org.postgresql" % "postgresql" % "42.1.4",
  "io.getquill" %% "quill-jdbc" % "2.2.0",

我的驱动程序实例是：

lazy val ctx = new PostgresJdbcContext(
    NamingStrategy(SnakeCase, PostgresEscape),
    AppConfig.quill
  )

此外，一些简单的sql测试成功。

如何将更新集SQL转换为scala quill？
