This property names the stored procedure that is executed for every poll call. If the property SPBeforePollCall has a value (the name of a stored procedure), then at the start of each poll call, the connector calls the stored procedure, passing it the values of the connector properties ConnectorID and PollQuantity. The procedure will update PollQuantity number of rows, setting the connector-id column to ConnectorID where status=0 and connector-id is null. This enables load balancing in the connector.
Default value: None
Possible values: The name of the stored procedure to be executed for each poll call
