function SetParametersIntoParameterList
(p_subscription_guid in raw,
p_event in out wf_event_t) return varchar2;
Description
Sets the parameter name and value pairs from the subscription parameters into the PARAMETER_LIST attribute of the event message, except for any parameter named ITEMKEY or CORRELATION_ID. For a parameter with one of these names, the function sets the CORRELATION_ID attribute of the event message to the parameter value.
If these operations raise an exception, SetParametersIntoParameterList() stores the error information in the event message and returns the status code ERROR. Otherwise, SetParametersIntoParameterList() returns the status code SUCCESS.
You can use SetParametersIntoParameterList() as the rule function for a subscription with a lower phase number, to add predefined parameters from the subscription into the event message. Then subsequent subscriptions with higher phase numbers can access those parameters within the event message.
Note: If the event message will later be sent to a workflow process, then the value for any ITEMKEY or CORRELATION_ID parameter can only contain single-byte characters, because the CORRELATION_ID attribute of the event message will be used as the item key for the process. The item key for a process instance can only contain single-byte characters. It cannot contain a multibyte value.
Arguments (input)
| p_subscription_ guid | The globally unique identifier of the subscription. |
| p_event | The event message. |
