minimize transaction logging

We use SQL PE 2000 in our lab to store sampled data (lots of data collected at high sampling rate) in real-time. i know this may be an uncommon use of SQL server. For this particular application, performance is much more important than data recoverability. In other words, once-in-a-while data loss is acceptable. Actually we have never used the transaction log for recovery since we started using the SQL PE in this way a few years ago. Certain transaction logging such as bulk deletion is particularly wasteful of the resource. As my understanding from reading the online book and some threads on this forum, the best thing we can do is using bulk-logged recovery model. I am not sure if that helps us at all because it seems that bulk deletion (i.e. DELETE FROM MyTable WHERE ..., may affect hundreds of thousands of records) is not on the list of minimally logged transactions.

I am wondering if anyone could share some good advice.

Thanks in advance!

Correct Deletes (or any normal DML command) are fully logged transactions. There is no way to disable this behavor in Microsoft SQL Server.

In order to reduce logging when deleting large amounts of data do the deletes in smaller batches. Something like this should work.

Code Snippet

set rowcount 1000

select count(*) from sysdatabases --This is just to get the loop started

while @.@.ROWCOUNT <> 0

BEGIN

delete from table

where something = somethingelse

END

This will do small deletes of 1000 records at a time which while still logged will be done in small batches so with the log in simple recovery mode shouldn't get very large.

Doing deletes in this method will take longer than a single large delete, but you don't have to worry about a large transaction log.

Denny, thanks for clarifying this.

I am wondering if reducing the transactio log file size helps the performance. My understanding is that the same amount of logging still takes place. We are not concerned about storage space that we have plenty. We truncate the log file periodically.

|||Reducing the log file size shouldn't effect performance (unless you shrink the file to small and SQL has to grow the file often). It is recommended to pre-allocate the file size so that SQL Server doesn't ever have to grow the file.

min value for a date

Hi,
I have the following query which returns
select
r.Rate_id, min(r.rate) MinRate, A.date
from
hotel_acc_rates R
inner join
hotel_acc_rate_avail A on R.rate_id = A.rate_id
where
r.hotel_id = 1147-- Legacy falcon
and R.room_type_id = 72-- Double room
and R.board_type = 6-- Bed and breakfast
and month(R.valid_from_date) <= @.month and year(R.valid_from_date) <=
@.year
and month(R.valid_to_date) >= @.month and year(R.valid_to_date) >=
@.year
and r.min_nights = 1-- Standard type
and a.date >= getDate()-- we dont go back in time
group by
r.Rate_id, A.date
order by
A.date, minRate
rate_id minrate date
100268231002008-02-08 00:00:00.000
100268241502008-02-08 00:00:00.000
100268241502008-02-09 00:00:00.000

100268231002008-02-14 00:00:00.000
However I want to exclude row 2 as it is the same day but a higher
rate. I am working on an extremley old legacy system which allows lots
of different rates for the same day to entered which does not help!.
The structure cannot be changed so I am stuck with what I have.
How can I rewrite my query without creating a temp table?

|||Hi
it seems that rate_id is not needed in the group by
selectmin(r.Rate_id) as Rate_id, min(r.rate) MinRate, A.date
fromhotel_acc_rates R
joinhotel_acc_rate_avail A on R.rate_id = A.rate_id
wherer.hotel_id = 1147-- Legacy falcon
and R.room_type_id = 72-- Double room
and R.board_type = 6-- Bed and breakfast
and month(R.valid_from_date) <= @.month and year(R.valid_from_date) <=
@.year
and month(R.valid_to_date) >= @.month and year(R.valid_to_date) >=
@.year
and r.min_nights = 1-- Standard type
and a.date >= getDate()-- we dont go back in time
group byA.date
order byA.date, minRate
Although the minimum rate may not correspond to the rate_id returned you
could try rejoining it to the original tables matching rate and date
(untested)
SELECT c.rate_id, b.MinRate, b.date
JOIN hotel_acc_rate_avail c
JOIN hotel_acc_rates S ON s.rate_id = c.rate_id
JOIN (
selectmin(r.rate) MinRate, A.date
fromhotel_acc_rates R
joinhotel_acc_rate_avail A on R.rate_id = A.rate_id
wherer.hotel_id = 1147-- Legacy falcon
and R.room_type_id = 72-- Double room
and R.board_type = 6-- Bed and breakfast
and month(R.valid_from_date) <= @.month and year(R.valid_from_date) <=
@.year
and month(R.valid_to_date) >= @.month and year(R.valid_to_date) >=
@.year
and r.min_nights = 1-- Standard type
and a.date >= getDate()-- we dont go back in time
group byA.date
) b ON b.date = c.date AND b.minrate = s.rate
order byb.date, b.minRate
This would not eliminate two rate_ids with the same minimum rate, this would
require grouping again.
