Adaptive Server writes the data for the following commands directly to disk, adding no entries (or, in the case of bcp, minimal entries) in the transaction log:
Unlogged writetext
select into on a permanent table
Fast bulk copy (bcp) into a table with no triggers or indexes
You cannot recover any changes made to the database after issuing one of these commands. To ensure that these commands are recoverable, issue a dump database command immediately before executing any of these commands.
