小编use*_*049的帖子

我正在使用ODP.NET 11.2.0.3.0的Entity Framework.我得到了持久性工作的一些表,但这一个平坦拒绝添加一个简单的新对象,我无法弄明白.非常感谢您的帮助.谢谢

这是代码.我通过模型浏览器从对象中删除了图像字段,并且在调用SaveChanges()时代码仍然失败.

var corpDirectoryEntities = new CorpDirectoryEntities();
var cc = new EmployeePhoto();
cc.UserId = 12345;   // NUMBER field
cc.ImageName = "imagename";   // VARCHAR2(100)
cc.Image = photoStream;   // LONG RAW
corpDirectoryEntities.EmployeePhotos.AddObject(cc);
corpDirectoryEntities.SaveChanges();

发生以下异常.

System.Data.UpdateException was unhandled by user code
  Message=An error occurred while updating the entries. See the inner exception for details.

有没有办法从命令行提供列表值？地图有变量合并功能，但似乎不适用于列表。我希望有这样的东西，但没有运气...谢谢

terraform apply -var "listvar=abc1" -var "listvar=abc2"

或可能

terraform apply -var "listvar=[abc1, abc2]"
