Is It Possible To Use rowid Column To Order Table In Room ?
The entity i'm using has no incremental column, just has a string column that is generated and assigned UUID values
@PrimaryKey var id: String = UUID.randomUUID().toString(),
var something: Double = 0.0
For some reason, i just need list the table reversely, but there is no any incremental column
But sqlite tables has a default rowid column gets increased automatically.
So then i just tried below query, but it didn't recognize rowid
@Query("SELECT * FROM Things ORDER BY rowid DESC")
fun getThings(): LiveData<MutableList<Something>>
Gives ordering term expected, got rowid
Any hint or solution ?
