Subject Re: Using Data Import Handler to invoke a stored procedure with output (cursor) parameter
Date Thu, 31 May 2012 17:44:14 GMT
Thanks for your response, Michael. Unfortunately changing the stored procedure is not really
an option here. 

From what I'm seeing, it would appear that there's really no way of somehow instructing the
Data Import Handler to get a handle on the output parameter from the stored procedure. It's
a bit surprising though that no one has ran into this scenario but I suppose most people just
work around it.

Anyone else care to shed some more light on alternative approaches? Thanks again.

 I would greatly appreciate if anyone could provide any pointers or hints on how to proceed.
