文档解释
ORA-28539: gateway does not support result sets
Cause: The client program tried executing a stored procedure that returns one or more result sets through a gateway that does not have result set support.
Action: Check the documentation for the gateway that you are using and see if it supports result sets returned from stored procedures. If it does not, then the only way of accessing such stored procedures is to upgrade to a version of the gateway that does support result sets (if such a version exists). If the gateway does have result set support and you are still seeing this error then contact Oracle customer support.
