This optional parameter allows you to control the SQL query
that is used to insert log messages into the database.
The default
is:
insert into RADMESSAGES (TIME_STAMP, TYPE, MESSAGE)
values (%t, %0, %1)
Where %t is translated as a special
character to the current time, %0 is converted to the message priority (in
integer in the range 0 to 4 inclusive), and %1 is converted to the log
message, quoted and escaped. MESSAGE will be truncated to MaxMessageLength
characters prior to insertion.
