Answer 1

如果没有发生特定错误，很难给出具体答案。您发布的代码可能是正确的。在所有场景中我都没有看到任何错误。但是，这里有一些我会开始寻找的地方。

您的命令语句是否格式正确？所有VarChar参数是否都接受1024个字符？你的任何字符串是否都进入长度超过1024的VarChar列？ Int16的returnStatus类型是否正确？

无论如何，这些都是一些开始的地方，如果你发布一些关于这个问题的更详细的信息，你可能会得到更多的答复。

Answer 2

我看了你的代码，没有看到任何怀疑请不要低估我但是...在类似的情况下我会做一个非常愚蠢的测试（我承认，这是愚蠢的）：在程序声明和运行它的代码中注释掉除第一个之外的所有参数，然后测试：如果有错误，你会知道它是第一个参数;如果没有显示错误，则取消注释过程和代码中的第二个参数我知道：这是愚蠢的，耗费时间和令人讨厌的......但是如果你真的觉得你在一个角落里关闭了，这可以让你更准确地暗示问题出在哪里。

Answer 3

~~DealerID被声明为Number，但是以字符串形式传递。~~

我怪滚动条，没看到Int32.Parse（）

Answer 4

没有.Net的经验，但我想知道OracleType.Int16是否是INTEGER参数的正确数据类型（根据http://msdn.microsoft.com/en-us/library/system.data.oracleclient.oracletype(VS.71).aspx，是一个NUMBER，需要一个OracleType.Number）？

OracleType.Int16：“这不是本机Oracle数据类型，但是用于在绑定输入参数时提高性能。”
