Android Room Embedded Relation 忽略 where 条件
Android Room Embedded Relation ignores where condition
我有一组有点复杂的带有@Relations 的table。这是我的第一个 table：
@Entity(tableName = "commodity")
class Commodity(@NotNull @PrimaryKey val id : String,
val __typename : String,
val name : String,
val isometricDrawingUrl : String,
val startDate : OffsetDateTime?,
val endDate : OffsetDateTime?,
val numberOfBlocks : Int,
val numberOfRejects : Int)
第二个table：
@Entity(tableName = "milestone")
class Milestone(@NotNull @PrimaryKey val id : String,
val commodityId : String,
val __typename: String,
val name: String,
val earnableHours: Double,
val currentStatusI18n: MilestoneStatus,
val approved: OffsetDateTime?,
val claimed: OffsetDateTime?
)
这是我的第一个@Embedded 符号：
class CommoditiesAndAllMilestones {
@Embedded
var commodity: Commodity? = null
@Relation(
parentColumn = "id",
entityColumn = "commodityId",
entity = Milestone::class
)
var milestones: List<MileStonesAndAllBlocks> = ArrayList()
override fun equals(other: Any?): Boolean {
return this === other
}
}
第二个嵌入关系：
class MileStonesAndAllBlocks {
@Embedded
var milestone: Milestone? = null
@Relation(
entity = Block::class,
parentColumn = "id",
entityColumn = "milestoneId"
)
var blocks: List<Block> = ArrayList()
@Relation(
parentColumn = "id",
entity = ApprovedBy::class,
entityColumn = "milestoneId"
)
var approvedBy : List<ApprovedBy> = ArrayList()
@Relation(
parentColumn = "id",
entity = ClaimedBy::class,
entityColumn = "milestoneId"
)
var claimedBy : List<ClaimedBy> = ArrayList()
}
问题是我不能做一个简单的查询：
@Transaction
@Query("Select * from commodity WHERE name LIKE '%' || :typeName || '%' AND numberOfBlocks > 0")
fun getCommodities(typeName: String) : DataSource.Factory<Int,CommoditiesAndAllMilestones>
运行 此查询 returns table 中的所有值。它似乎忽略了 where 子句，尽管嵌入式关系有效 - 列表结构就像我所期望的那样。如果您使用 Room Relations，您可以在 where 子句中设置条件吗？

我已经创建了这个测试文件，显然您可以使用 Where 子句进行查询。

Can you do conditions in where clauses if you are using Room Relations?
是的。
根据您的代码考虑以下内容：-
