Deleting Log file

Hello
Is there any time / way /procedure to delte the log file and let SQL
recreate it without losing any data. In other words - at what point in time
can one be safely assured that all data in the log file is committed to the
database.
reason - have 1.2gb database and 9gb logfile - caused by duplicating
another database ( importing thru ODBC ) each night and would like to kill
the log file each morning after the transfer - the SQL database is only
used for reporting as the other package has lots of limitations - yep - we
are working on converting it all to SQL so this replication doesn't have to
happen but that is still a fair way off
TIA
PeteIf your recovery plan is to restore from your last full database backup (or
rerun your import), you can set the database recovery model to SIMPLE so
that committed transactions are automatically removed from the log.
You can run DBCC SHRINKFILE to release unused log space back to the OS. The
log will still need to be large enough to accommodate your largest
transaction so you probably don't want to do this routinely.

Hope this helps.
