无法更新 Room Kotlin 中的实体

Question

我需要更新整个实体，所以我尝试使用 @Update 但它不起作用，并且使用 UPDATE 查询有太多字段。那我该怎么办？

@Update
updatePackage(item: Package)

@Query("UPDATE PackageEntity SET weight = :weight ...[[TOO MANY FIELDS]] WHERE id = :id")

    @Entity
    data class PackageEntity(
    @PrimaryKey(autoGenerate = true) var id: Int? = -1,
    @ColumnInfo(name = "weight") var weight: Double = 0.0,
    @ColumnInfo(name = "unitType") var unitType: Options.UnitTypes = Options.UnitTypes.MT,
    @ColumnInfo(name = "high") var high: Number = 0.0,
    @ColumnInfo(name = "length") var length: Number = 0.0,
    @ColumnInfo(name = "wide") var wide: Number = 0.0,
    @ColumnInfo(name = "quantity") var quantity: Int = 0,
    @ColumnInfo(name = "description") var description: String = "",
    @ColumnInfo(name = "loadType") var loadType: Options.LoadTypes = Options.LoadTypes.GENERAL,
    @ColumnInfo(name = "cityOrigin") var cityOrigin: SimpleClass = SimpleClass(),
    @ColumnInfo(name = "cityDestine") var cityDestine: SimpleClass = SimpleClass(),
    @ColumnInfo(name = "pickup")var pickup: Boolean = true,
    @ColumnInfo(name = "deliver")var deliver: Boolean = true
    )

Answer 1

嗯，这很奇怪......你可以尝试类似的东西

@Insert(onConflict = OnConflictStrategy.REPLACE)
fun updatePackage(item: Package)
