An interesting suggestion, but the problem with storing the logfiles in
a table for us would be that uncompressed, the log file for a day is
about 10 gigs. This would mean that an unacceptable amount of excess
data would accumulate in the database. It would be feasible however to
write a script to import the archived logfile into a new temporary
database on a different server, then use SQL to search it and delete the
db when finished.

Thanks for the suggestion though.

Ben.
