This SQL statement is executed whenever Radiator needs the
number of sessions currently logged on to a particular NAS. This is only
required if HandleAscendAccessEventRequest is defined and an
Ascend-Access-Event-Request is received and Radiator finds that there is a
session in the session database that is not recorded in the NAS. %0 is
replaced by the NAS IP address and %1 is replaced by the session ID. SQL
bind variables are supported.
It defaults to:
delete from RADONLINE where NASIDENTIFIER='%0' and ACCTSESSIONID = %1
