Kotlin Android Room 数据库删除查询问题

Question

I need some help with my code. I'm trying to delete multiple items by uid from my room database, but even if it's in a loop, it deletes only the first item it finds and that's all...

The sample from my Dao:

@Query("DELETE FROM itementity WHERE uid = :itemUid")
fun deleteByUid(itemUid: String)

How I delete multiple items:

    GlobalScope.launch(Dispatchers.IO){
        itemsObject.forEach {
            db.itemDao().deleteByUid(it.uid)
        }
        
    }

Answer 1

You can try something like this:

@Query("DELETE FROM itementity WHERE uid IN (:uidList)")
fun deleteAllInList(uidList: Array<String>)

And now You can delete it just by passing itemsObject as an argument.

Let me know if it is working, I was doing like that but with LongArray not Array<String> so I am not sure if it works.
