This SQL statement is executed whenever a NAS reboot is
detected. It is expected to clear the details of all sessions on that NAS
from the SQL database. Special formatting characters may be used (the
%{attribute} ones are probably the most useful). %0 is replaced by the NAS
identifier. If ClearNasQuery is defined as an empty string, then the query
will not be executed. SQL bind variables are supported.
It defaults
to:
delete from RADONLINE where NASIDENTIFIER='%0'
