Room: Conflicting Declarations

I would like to add value, date and details to the current pb. I am receiving an error 'conflicting declaration' in the database for pbInfo. How should I fix this error?

@Entity(tableName = "pb_table")
data class Pb(@PrimaryKey
              val pb: String)

@Entity
data class PbInfo(@PrimaryKey
                  var value: Double,
                  var date: Int,
                  var details: String)


@Dao
interface PbInfoDao {


    @Insert
    fun update(vararg pbInfo: PbInfo): LongArray


 INSTANCE?.let { database ->
                    scope.launch {
                        populateDatabase(database.pbDao(), database.pbInfo())
                    }
                }
            }
            suspend fun populateDatabase(pbDao: PbDao, pbInfoDao: PbInfoDao) {
                pbDao.deleteAll()

                var pb = Pb("Squat")
                pbDao.insert(pb)
                var pbInfo = PbInfo(122.5, 28, "I was feeling on top form today!")

First of all, you have two Entities in a single class (possibly the conflict)

So, add separate class for separate Entity.

Then, in your RoomDatabase abstract class, add two Entity Classes like this (and also create separate Dao interface classes):

@Database(entities = [(Pb::class), (Pbinfo::class)] ,version = 2)
abstract class YourRoomDatabaseClass: RoomDatabase(){
    ...
     abstract fun pbDao() : PbDao
     abstract fun pbinfoDao(): PbinfoDao
    ...
}

This should solve the conflicting of Entity classes. I have a single database with two Entities just like this and running without any problems. (Please mind me because I don't know Kotlin Syntax)

Use this

@Insert(onConflict = OnConflictStrategy.REPLACE)

instead of

@Insert
