房间搜索查询

Question

当我想使用房间查询在数据库中搜索用户时，我必须输入全名才能获得结果。如何在数据库中逐字母搜索？

    @Query("SELECT * FROM database WHERE name LIKE :search")
    fun find(search:String?):List<User>

Answer 1

尝试

@Query("SELECT * FROM database WHERE name LIKE :search")
fun find(search:String?):List<User>

search = "%Kourosh%";
find(search);

//OR

@Query("SELECT * FROM database WHERE name LIKE '%' || : arg0 || '%'")
fun find(search:String?):List<User>
