Reducing Reads Question

Aug 24, 2007

I'm trying to insert all the rows from a table to a new table.
(insert A select * from AA)
The reads on Profiler shows ar really high value (10253548).

First I created a unique clustered index and the reads shows (3258445), then I created a non clustered index expecting to have lower reads. Instead the reads shows (10253548).

I read creating indexes helps reduce reads. But it's not happening.
Any ideas what is going on?

Reducing 3 SQL Transactions To Just 1

Jan 9, 2008

Hi guys, how are you?

Ive got a little question, i hope you can help me up

in sql server i have 3 tables

Code:

user
id_user - autoincremental int, primary key
username - varchar 30

car
id_car - autoincremental int, primary key
carName - varchar 30

user_car
id_user - int, foreign key
id_car - int, foreign key

what i want to do, is to
1.- insert a row in User,
2.- insert a row in Car
3.- using SCOPE_IDENTITY, to insert a new row in user_car that relates the ids of the last added car with the last added user.

But i need that to be done in one single transaction.
Once that is done, i have another question

how can i do the same but where i can add a variable number of different cars? in other words, i add 1 user and then add 5 cars, then create 5 rows in the user_car where i have the id of the last added user with the incremental id of the last 5 added cars

how can this be done in one single transaction, i cant make it in 3 transactions cuz it would cause me a lot of trouble. Any help?

my transaction should be something like this

Code:

insert into user(username) values('user1');
insert into car(carName) values('car1');
insert into user_car(???,???)

but im not sure how to do this in one single transaction

Reducing LDF Files

Apr 18, 2007

Hi,
If I understand it correctly, you only need an LDF file to restore to a point in time after the last full backup? If this is so, then Could the LDF file not be reduced in size on perfoming a full backup?
Most of the time it's not an issue as there is enough space on the HDD, but is it possible to reduce the ldf file size periodically (manually would be fine). Is changing the recovery mode from FULL to SIMPLE and then back to FULL an option?
If so, is anyone able to tell me how, exactly, I can do this? ... I've sifted through the documentaion to no avail ... :eek:
Many thanks
Rob

Reducing Number Of Extents

Jul 29, 2002

Hi all,

I have started to look at the way our production DB has been defined and set up, with the view to improving performance.

The DB is now 11gb, and the original size was set up as 3000mb, the rest has been take in 10% additional extents.

Now, back in my DB2 DBA days, this was a bad thing to have any data spread across extents as they may not be contiguous. I am assuming that is the same with SQL Server. Can someone confirm/deny this?

If this is the case, how can I get the DB back into one primary partition?

Thanks in advance.

Mike

Archiving Is Not Reducing DB Size

Jan 10, 2005

I created few jobs that would archive the production DB and delete the archived data...
but it looks like the DB size is not reducing!!! Some times it looks like the size has increased!!

I think this is because of the log file size has increaded by the DELETE operations....But what can I do for this???

Reducing Redundancies In XML Output

Feb 9, 2012

Having difficulty achieving an end-result in transforming the results of a rowset query into XML.

Here is simplified test code that displays my problem:

declare @TimesheetHdrs table (EmpID int,EntryYear smallint,EntryPeriod tinyint,AdminNotes varchar(max),UserNotes varchar(max))
declare @TimesheetDtls table (EmpID int,EntryYear smallint,EntryPeriod tinyint,ProjCode varchar(25),ActCode varchar(25),ExpendCode varchar(10),EntryDate date,EntryQty decimal(7,2))
declare @Projects table (ProjCode varchar(25),ProjName varchar(200))

[Code] ....

The result of the above code is the following:

Code:
<root>
<timesheet empid="1" entryyear="2012" entryPeriod="1" adminnotes="These are the admin notes" empnotes="These are the user notes">
<project projnum="TestProject" projname="The really big project for our best customer">
<activity actcode="000103020200302302322" actname="Demolish the 55th story of the main tower">

[Code] ....

Notice how there is a tremendous amount of redundancy in the XML. I was hoping to come up with an XML result of the following, which transmits the same data, without the redundancies.

Code:
<root>
<timesheet empid="1" entryyear="2012" entryPeriod="1" adminnotes="These are the admin notes" empnotes="These are the user notes">
<project projnum="TestProject" projname="The really big project for our best customer">
<activity actcode="000103020200302302322" actname="Demolish the 55th story of the main tower">
<expenditure expcode="1" expname="Regular Hours">

[Code] ....

Help Reducing DB Performance Issues

May 19, 2008

Hi all,

We currently have an e-commerce app written in .NET with SQL Server backend and built-in CMS that works just fine. We are now implementing a service to remove the need for the CMS by automating the synchronisation of the e-commerce database with a back-office database (non SQL Server). The problem we have run into is that during some of the larger updates to the website (i.e. new product information), the e-commerce system is experiencing timeouts. The synchronisation service uses transactions while performing updates and so I am assuming that the timeouts are being caused by the transactions locking tables and data.

What steps can I take to try to reduce these locks? The transactions are as short as possible so I do not think we can reduce the amount of processing each transaction deals with. I was looking at different isolation modes, Snapshot in particular, to reduce the locks, but would like some advice from someone who may have dealt with this type of situation before I start messing around here. (The synchronisation service uses the default ReadCommitted level, BTW)

Any advice you have to offer will be much appreciated.

Regards,

Stephen.

Reducing Log File Size

Feb 12, 2008

I have a database who is in full recovery mode. I have four maintenence plans setup: database backup, log backup, optimization and integrity checkup. The last two plans run weekly and the first two run daily. I found that the log size often increase to a dramatically size in a very short period, almost same size as the database file (4G). Further I found that the size seems increase a lot after the last two plan runs.

My question is that the optimization operation(reconstruct index page) will write any reocord to log file? Is this possible a reason?

Now the log file occupy too much disk space (90% of space can be free). What I should do? Shrink database weekly?

Thanks

Many Reads

Mar 25, 2008

Hi!
I was assigned to solve performance problems for an application. I fired up Sql Server profiler and started a trace. Downloaded Sql Server Trace Analyzer. It's a trial version so it's very limited. What I found is that one stored procedure generates almost 400 000 reads everytime it's used and it's used everytime the user wants to see his orders. I've tried to translate the t-sql to english from swedish, it looks something like this:

select top 100
o.orderid,
o.name,
o.latestdeldate,
os.name as OrderStatus,
os.orderstatusID,
p.placeID,
p.name as place,
p.address,
p.city,
a.name as worktype,
noOfActions=(select count(*) from actions a where a.order_orderid=o.orderid),
noOfServiceObjects = (select count(*) from Serviceobject s, Actions a where s.Place_PlaceID = o.Place_PlaceID and a.order_orderid = o.orderid and a.Serviceobject_serviceobjectid = s.serviceobjectid),
...
...
...

It has 8 select count(*) in the select statement then in the where statement it has 2 more select count(*).

I know it's very difficult for you to come up with a solution but do you know a better way than to use select count(*) everywhere? The count is used for to show different status flags on the website.

Reducing Database Size (contains Images)

Jun 8, 2004

Hello. I am wondering how to effectively reduce the size of my database. After viewing the individual table sizes, I have come to realize that nearly 99% of the database's size is due to images. I am told that too much binary data is not good. How can I go about reducing the size of my database (possibly the images themselves)? I'd appreciate any help.

Reducing The Size Of The Transaction Log File

Oct 3, 2006

At this time I am only playing with the applications that generate the data and send it to the database. Without doing too much, and with deleting most data tables that were created, my transaction log file has grown over a gigabyte. I tried using the SQL server management studio (express) to shrink the database (tried shrinking files, too) but that did not make the file smaller. Right now there is hardly any data in the database (6 tables, a dozen columns and rows each) so it must be old transactions that are kept in the log. How do I get rid of the old data and make the file size smaller? Thanks.

Automatically Reducing Precision On Numerics

Mar 26, 2008

Hi all,

I'm running a transformation script that's taking decimal(18,10) data and trying to shoehorn it into a numeric(9,6). generally this works, as most of the data in the original table is not using anywhere near the precision it's capable of, but once in a while I run into one that does use it.

Is there any way to automagically reduce the precision so that i can cram the data into the destination table?

Reducing Excel Rendering Time

Feb 20, 2008

We have a reporting system where the default rendering format is HTML.
HOwever, in some cases user may export the data into Excel aftergenerating
the report in HTML. Howveer, this export is taking too much time. eg 5500
row report in HTML takes around 8 minutes to export into excel. Is there a
workaround for this? Please note that default rendering has to be in HTML
only.

Also another feature noticed is that in RS 2005, the report server execution
log seems to be logging seperate entries for export feature as well. This
was not happening in RS2000. Is this a new feature in RS2005 or is the
underlying SP for the new report being called again when the export to excel
happens?

Any help would be appreciated

----------------------------------------------------
Making story short. I got an application that hits only 1 database called RECORDS. I'm getting different duration when running an application. 23 and 3 seconds.
Same database, same objects and same application.
SERVER QAT is our staging server, means lots of databases
SERVER MILLER is just a server i just assembled, means just one database (RECORDS).

Not sure if it's because it's a clustering server that is causing the issue nor the reads. If its the reads, what is causing it? Do you think is the how the memory is configured?. Will the experts pls stand up?
