Hello,
Earlier,As there is no tecnical / Syntactical errors existing and was perfectly running the report earlier and yielding the result in quick time.
But my Application running well earlier and If I execute the SP or report for which It takes more time what would be the consequences and what and where I should do and begin to see the problem.
Thanks for your time and reply.
Good Morning Everybody,
I had a single table consists of one million records. To retrive data from that table it takes lot of time. how i can reduce execution time?
what is the procedures to tune the database. i implemented cluster index on primary key of that table. still i can't able to reduce execution time.
can anybody help me in this issue?

Hi there

what is so significant about record number 215???
thanks
I use Sql server 2000.I have implemented paging as guide in link :
http://dotnetjunkies.com/Tutorial/975BE770-E5DC-4610-870B-A82BDB9B8845.dcik
Is peformance good ? My database has 200000 records.
I feel my web application quite slowly in loading.
I suppose that 100 user simultaneously run in store above links.Mean that it create 100 temp table and load 100 * 200000 records.is it correct ?
Please give me valueable suggestion about performance.
Thank you very much.
Does putting a select statement in a stored procedure provide any performance benefits over leaving the sql in the data view of the report?
TIA

Hi
Is there any good books for Query Tuning and Stored procedure Tuning
Thanks
So this could be a long story.
Server1 = Previous "Test box", Windows Server 2003 Standard, SQL 2005 Standard SP1 with hotfixes, 2 processor 4 gig RAM
Server2 = New "Box for production", Windows Server 2003 Enterprise, SQL 2005 Standard SP1 with hotfixes, 2 Dual Core Processor, 16 gig Ram
This is for a datawarehouse environment. I pull a lot of data every night from an Oracle database. On Server1 the process took about an hour to pull all my data accross, on Server2 it takes more than 3 hours. I use SSIS packages to pull the data accross.
Even just running an OPENQUERY statement takes a lot longer. On Server1 returned about 150K record in 1.5 minutes and now on Server2 it only return 40K.
Have I missed a setting on my re-install. It the same SQL build number, SP_Configure has exactly the same settings and everything seems the same. I ftp'ed a file from the oracle box to each of my boxes and had very similar results, so it doesn't seem to be a network issue.
Any help would be much appreciated, is there anything that would cause SQL to pull data 3 times slower from an external datasource?
Thanks in advance guys,
Regards.
Hey,
SQL Server 7.
I have a view which joins 3 tables. One has 15 million rows the next another 5 million and the third 500k.
When I join them the execution plan tells me that 15 million rows were retrieved from the first (taking about 5 mins) 1.5 million from the 2nd taking 3 mins and 4.5 million from the third taking almost no time.
The first two ause a clustered index, one being a seek the other a scan and the third a regular index seek. All followed by a hash match/inner join which takes 2 mins.
Any ideas on optimizing the SQL?
Here is the syntax:
SELECT b.packno, b.COMM_DATE, a.ben_grp_cr, a.ben_dsc_cr, c.gst_inc,
SUM(a.credit)
FROM TABC c INNER JOIN TABB B
ON b.PACKNO = c.PACKNO AND
b.COMM_DATE = BENDTL.COMM_DATE AND
b.BEN_NUM = c.BEN_NUM INNER JOIN
TABA a ON b.tran_id = a.tran_id
WHERE b.tran_date > '20040401' AND c.gst_inc = 0
GROUP BY b.packno, b.COMM_DATE, a.ben_grp_cr, a.ben_dsc_cr,
c.bendtl.gst_inc
I tried on finding out the problem in a slow running sp with profiler. I found that there are some waiting resource 'tracewrite' and 'async_network_io'. Any idea on it? Thanks in advance
View 4 Replies View RelatedI need to find a way to make this query run faster. Please let me know if you can help. Here are some of the issues.
1) I have a database with one table, and No indexes can be put in place.
2) This is a very large database. (4,000,000) records, and growing daily.
3) the following query returns 720,000 records.
4) The query takes about 18 minutes to complete.
I understand that by doing a table scan, the way this has to run is difficult, but is there anything I can do?
The Problem: When I run this query, I also run performance monitor, I have found that my page file is at 100%. I have 1 Gig of Ram on the server with 2 P III Xeion Processors. I don't know what other information I can give, but please let me know.
Thanks for you assistance

I want to use the Index tuning wizard on some of my tables. Is it OK if I use when people are on the server or to do it during off-pick period. Thanks!!!
View 1 Replies View RelatedHey all,
I am interested in finding out if anyone out there has experience with extremely high-performance SQL Server applications. The I/O needs of my database server are growing very quickly, and I am on the verge of launching a major upgrade project.
We have done all the standard tuning tasks: proper indexing, stored procedure tuning, etc... and are running on good small-server scale hardware ( dual PIII 700s, 1G RAM, but no RAID). The only path I can see to achieving higher performance are:
- lots of RAID, perhaps on a SAN.
- server upgrade, maybe 4 proc? I've been looking at RAIDZONEs and Netfinity's
- data partitioning ( I REALLY want to avoid this if I can! )
What do you do when you need Major Enterprise scale database performance from SQL Server? I've found lots of resources for Oracle and DB2, but I can't find many case studies for serious SQL Server installations.
Help!

Hi,
does the upgradition SQL Server 6.5 to 7.0 will simply solve some problems which we are facing currently like ODBC errors Insert failed and update failed and also supporting more users ?
We have Access front end to SQL Server backend, so do we need to touch code in front end for optimizations ?
Can any pls guide me on this
Thanks
Does anyone know of any good reference material on how to tune SQL Server 7?

Hi !
In the older versions 6.5-7.0 you could adjust max_async_io setting if you had fast controllers and disks that could handle more IO from SQLServer. In 2000 this setting is removed. Are there any settings that I could adjust/tune regarding IO and disk handling ?

Hi Guys I need someone to assist me in having full understanding of what performance turning is. My Challenge is interpreting the System Monitor Graph of Performance tools.
I needed to know what does the value on vertical axis represent, while there is non on the horizontal axis rather I have Last, Average, Minimum, Maximum and Duration; Please What does all this value stands for, I indeed observe that when I click on any of the counters selected the value changes, therefore kindly assist me so that I can make meaning of this. Apart from all this please assist me with any material that can explain performance tuning to my maximum benefit, thanks in anticipation.
