In what situations will the error "executeupdate, exception = NULL" occur?

Unfortunately, errors occur during programming. Fortunately, development software such as. Net or myeclipse will give us some detailed error messages. However, if the following error occurs,

Error detailmessage = "executeupdate, exception = NULL"

No detailed error information. How can this problem be solved. My suggestion is to keep in mind the situation, because this error is not very common.

I encountered a situation where the type defined in the Oracle stored procedure is both input and input variables. Such a stored procedure can be debugged and run in the database without errors.

Procedure testsp
(
_ P in out int;
) Is
Begin
-- Do something
End;

Then an error occurs when running the following code.

Callstatement. setint (1, 123456 );

Hope to communicate with you. Thank you.
