我无法将oracle适配器的更新命令设置为Oracle

System.NullReferenceException:对象引用未设置为对象的实例


是否有人知道为什么?有人能告诉我如何成功将我的

数据适配器的更新命令设置为我的存储过程


感谢您的帮助

I am having trouble setting the update command of my oracle adapter to the name of an Oracle
stored procedure. My data adapter is a global variable that I use in multiple functions.
But the following line of code

g_Da.UpdateCommand.CommandType = CommandType.StoredProcedur

Generates this error
System.NullReferenceException: Object reference not set to an instance of an object

Does anyone know why? Can someone tell me how I can successful set the update command of my
data adapter to my stored procedure

Thanks for your help

要么你没有创建DataAdapter ,或者你没有创建一个

UpdateCommand。

Either you didn''t create a DataAdapter, or you didn''t create an
UpdateCommand.

您确定已为UpdateCommand分配了一些内容吗? ''属性?

Are you sure you assigned something to the ''UpdateCommand'' property?

是的,但它不起作用:


g_da.UpdateCommand = Something

"yes, but it does not work:"

g_da.UpdateCommand = Something
