What's the difference between DELETE TABLE and TRUNCATE TABLE commands?..

Answer / skybeaver

"Delete TableName" is a logged transaction. Every row
affected by the delete will be written to the transaction
log. This is done for RECOVERY purposes, so that the
transaction may be rolled forward from a previous database
dump.

"Truncate TableName" is non-logged. It removes all rows
from the table and releases all allocated segments in the
database, all without logging anything. This is not
something a developer does, but rather is done by a DBA as
part of some sort of housekeeping.
