There is no way to turn off logging, as an interrupted non-logged operation
would mean that the database would be kapoot.
There is a minimlally logged operation SELECT INTO, which also creates
the table. It's minimally logged if your database is in BULK_LOGGED
recovery. (And I think SIMPLE.)
Another alternative is to perform an INSERT in batches:
WHILE 1 = 1
BEGIN
INSERT target (....)
SELECT TOP 50000 *
FROM source
WHERE NOT EXISTS (SELECT .... FROM target WHERE ...)
IF @@rowcount < 50000
BREAK
END
For this to be meaningful, the database should be in SIMPLE recovery
mode, so that the transaction log is truncated after each batch. (Or
if you are running in FULL or BULK_LOGGED mode, you would need to
backup the transaction log as the loop as running.
