左连接上的UnexpectedNullableFound

Question

您好我遇到了一个UnexpectedNullableFound的问题。列可以返回空值，但我将其映射（如下所示）作为选项，因此不应该导致问题。这适用于我从该表中获取的其他字段。如果我删除＆＃39; pe.company AS admin_company＆＃39;和代码中的相关映射，我没有任何问题。

如果admin_company为null，我会遇到此问题。如果没有，它执行得很好。

我已经阅读了很多相关问题，但是在这里找不到任何解决方案。

有关于此的任何想法吗？感谢

Answer 1

我的问题的解决方案是将所有别名更改为大写。现在使用Anorm 2.4

可以正常使用

我的新代码如下，它还包括一些重构，但大致相同。

  get[String]("useas") ~

  get[Boolean]("is_invoice_customer") ~
  get[Option[String]]("test_users_invoice_email") ~
  get[Array[Byte]]("password_hash") ~
  get[Array[Byte]]("salt") ~
