android - 在 Room Database Android 中为@DatabaseView 传递参数

Question

我有一个像这样的 databaseView 代码。

@DatabaseView("SELECT * FROM Product")
data class ProductDatabaseView(
    var productCode: String? = "",
    var productName: String? = "",
    var longDescription: String? = "",
    var productUom: String? = "",
    var customerCode: String? = "",
    var price: String? = ""
)

我想传递一些值(value)，就像我们在 DAO 中所做的那样。

@DatabaseView("SELECT * FROM Product WHERE priceListCode = :priceListCode")
data class ProductDatabaseView(
    var productCode: String? = "",
    var productName: String? = "",
    var longDescription: String? = "",
    var productUom: String? = "",
    var customerCode: String? = "",
    var price: String? = ""
)

它是否能够像这样传递值，或者在 View 的帮助下是否有任何其他选项可用。

据我所知，不，你不能将参数传递给 @DatabaseView。它们的工作方式与 sqlite 中的工作方式相同，后者不允许在 View 中使用参数。
