[HACKERS] invoking Web service in user-defined function in a dynamic way.

[jungmin shin]

I created a user-defined function which has a remote Web serivce invokings inside and executed with select statement.

 

select <functionname>( parameters)

 

When I implemented in a static way of Web service invoking, it worked.

However, when I tried with a dynamic invoking, I had following errors.

Most time, the "ERROR" part is appeared as a result.

Does anybody know about this?

 

 

Thanks,
