I used SqlConnection/SqlDataReader to read data from SQL Server 2000 in my ASP.NET project, but I found that the CPU usage is too high, and I used SQL Query Analyzer to run the same SQL statement, The CPU usage is the half of the previous, is there anyone can tell me why? Thank you!
Hi everyone!Being new the SQL, I wanted to ask everyone if there are good resources out there that they use? I could use all the help I can get! Books, links, websites, etc.Recently my friend sent me this, I found it informative and best of all, free! https://store.pentontech.com/index.cfm?s=9&promocode=qe2165f7 Thanks in advance for your help!- Lizzy
Sometimes logging in to SQL 7 I get 'Memory resources not available...' and log in process terminates. Do I need to up number of locks ! If so, how ! Pls. suggest any other ideas !
This proc will show you what is using SQL system resources right now. If a process is not currently using any resources, it will not show up on the list. Also, a dump of the input buffer is printed so you can see just what is going on.
I use this code whenever somebody whines that "The server is slow!".
The magic is ::fn_get_sql which came with service pack 3 for sql 2000.
use master IF (object_id('sp_Now')) is not null BEGIN PRINT 'Dropping: sp_Now' DROP PROCEDURE sp_Now END PRINT 'Creating: sp_Now' GO CREATE PROCEDURE sp_Now as -- FULL DETAILS OF WHAT IS RUNNING set nocount on declare @handle binary(20), @spid smallint, @rowcnt smallint, @output varchar(500)

Hi, Im just looking for someone that has a demonstration Visual Basic database script. Something that makes a database, ad / removes rows and information, does all basic database stuff, just as an example of how a SQL database is supposed to be handled.
I know that a query inside a called UDF does not show up when displaying theestimated query plan, but are the resources (CPU, DiskIO) used by a UDF thatis call from within an SProc or embedded in a SQL statement included insp_who2 and Profiler BatchCompleted?Also how performance draining is it to do something like the following. Iassume for every row returned the udf will be called causing 8000 tablescans on DateTable?Create Functionu udf_GetCountDates (@StartDate datetime, @EndDate datetime)Returns IntbeginReturn(select count(*) from DateTablewhere ColDate > @TestDate and Col1Date <)end--DateTable has 5,000 rowsCreate proc Test@TestDate datetimeAsselect Col1, Col2, udf_GetCountDates(@TestDate, Col2)From OTable--OTable has 8,000 rowsGoThanks,Ray
I have a question...say I have an asp app that works as a front end toan sql server 2000 database. Would it be better, performance wise, toseperate the webserver from the sqlserver or to have them on the samemachine?-Jim
I have a sql job(that runs several stored procs) that is run to fix a problem, it is set to run every few minutes (no, this is not my idea). What would be the best way to identify how much this specific job/and it's sp's are using in resources, such as cpu and memory?
I was thinking of doing certification from Microsoft. I was first intending to write exam 70-229 which is : Designing and Implementing Databases with Microsoft SQL Server 2000 Enterprise Edition.
The Microsoft site http://www.microsoft.com/traincert/exams/70-229.asp#TOOLS has a list of topics that I need to be familiar with in order to pass the exam, but it does not have the detailed information. Can someone guide me to a place where I can go to get the detailed information about these topics so that I can prepare better for the certification exam? thanks Aslam
Hi folks, thought I'd wade into the mssql waters, I've used mysql for some time, thought I'd familiarize myself with the other.
I downloaded mssql server 2005 express edition. Don't know if I missed anything on the site, maybe I did. I've got it running from the command line.
Are there any GUIs out there that are decent to use? Where can I download it?
Is there a specific manual available like mysql has? I think I stumbled across something but wasn't sure it was searchable, sorry the link is on my other 'puter at the moment so I can't see what I was looking at.
perhaps a sticky in this forum with good resources would be helpful to all.
I normally develop for MySQL and PHP, but we have a new application that runs on MS SQL and I'm having difficulty using the same structure as MySQL to run queries. Can someone here point me to a good resource to learn the basics?
I have a problem on microsoft sql server 2000. I need to limit the amount of resources(eg cpu, mem..) a query uses Is there a way to do this in SQL server 2000
There are many Errorcodes which SSIS uses to represent errors, warnings etc.
List of errorcodes are at: http://msdn2.microsoft.com/en-us/library/ms345164.aspx
Now, in my SSIS package, I have defined error handler(OnError) and warning handler(OnWarning) to handle the events. Which logges them to a flat file with some formatting and condition checks including addional information about faulty row.
I dont want to log the exact error messages sent by SSIS as they are too much technical and not understanadble by normal user. I want them to be replaced with some custom message which I 'l pick from some resource file by matching the ErrorCode. One can consider this resource file as collection of key(ErrorCode), value(Custom Error Message) pairs.
In .NET we normally use resource files(.resx) to achive the same task. I found no way to use such resource files in SSIS.
Is there any way by which I can implement this functionality?
I dont want to implement custom logging mechanism as it does not fit into my application needs. Please guide.
SQL Server is using up all of my system resources and i can't find where the problem is, i have used
exec sp_who
exec sp_who2
but i don't know what to look for, i'v even checked the memory comparison according to SQLSkills but that is all fine, the server is extremely slow all the time. I battle to open Query analyser or even just to connect to it takes forever, any advice would be greatly appreciated.
The errormessage after a deadlock gives very little information: "Your transaction (process ID #12) was deadlocked with another process and has been chosen as the deadlock victim. Rerun your transaction."
But what resources, ie tables, indexes etc, are really deadlocked?
Is it possible to set a switch or something to log all relevant information about a deadlock for later investigation?
Anybody have a suggestion on text books or other materials that deal with performance tuning in SQL 7.0. From what I have seen SQL 7.0 is far diffrent than 6.5. I'm specificaly interestd in information about query plans, profiler and what a table spool does.
a) Thanks for all contributions on this site, they have been very useful but, i am trying to implement a security procedure including auditing on sql server 6.5,7, sybase and oracle can anyone help?
b) does any one know any site like this that covers issues on oracle ( besides Oracle Technet)?
We've got a 3rd party application that periodically runs SQL commands throughout the day. We've been getting issues with this application showing a sql error:
Transaction (Process ID 71) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
In checking the processes on SQL Server, there were a lot, and process ID 71 was actually hitting a completely different database.
Is there a way to streamline how SQL Server handles processes, and what's the limit at any given time?
Will I am running SQL 2005 Express on windows 2003 sp1 with a P4 3.4Gh (with hyperthreading), 2GB ECC RAM. I am running software that connects to SQL and reads/saves data. One of the programs which is CPU hungry manages data and the other manages the SQL connection and reads/saves the data.
My problem is that I am recieving an error that usually means connection to SQL is lost, this tends to be because the CPU hungry application is denying SQL from functioning.
However the annoying thing is the CPU use rarely passes 45% and in a another test environment never passed 5%. RAM is the same, consumption is less than 35%.
Hi,We have a heavily used production server and a table which logs everyhit on a web site. This table has grown large over time and we want toclear it down as efficiently as possible. We would like to issue atruncate table statement, but with millions of rows we are a bit waryof how this will affect server performance. The alternative is todelete is stages using rowcount but of course this will generate alarge amount of logging.Can anyone confirm whether issuing a truncate table will have anyaffect on performance - i.e. does it just clear a header block ordooes it have to do more?CheersMartin
Seems to me like microsoft mentions learning, but it's never for beginners. I haven't found a single tutorial that says how to make a simple database step by step.
Does anybody know about a tutorial focused on teaching the very basics (a kind of "hello world" application) from setting up the new database with a few sample fields to "deploying" it (making it ready to be used)?
Please let me know.
Once I'm through with these first steps there seems to be a lot of helpful learning resources meant for experienced and expert users, but I'm not there yet...
I'm using service broker queue with internal activation to run a stored procedure. The DB server is windows 2003 R2, 4 cpu, with SQL server 2005 SP2. When I'm runing the stored procedure directly from the sql management studio it takes about 75% of the cpu and running for about a minute, but when the stored procedure is activated by the queue internal activation (as a background process) it uses only 25% of the machine cpu (my guess it uses only 1 cpu insted of all 4 cpu) and running for much longer time (sometimes even more than one hour). How can I change this behavior? I want it to run as fast as possible.
The queue decleration is:
CREATE QUEUE [TaskQueue] WITH ACTIVATION ( STATUS = ON, PROCEDURE_NAME = ProcessTasksProc, MAX_QUEUE_READERS = 1, EXECUTE AS SELF);
Can Resource Files (containing, for example, string resources holding the text of exception messages) be part of a .NET project holding Sql Server CLR Stored Procedures?
hi! I'm still fairly wet behind the ears when it comes to databases, especially sql server 2000. But I just got a copy from my University and I really want to spend some time messing with it. The first thing I want to try is making a shopping cart that stores the items in the database rather than in the session. I'm using asp.net (VB) and I had previously made a simple shopping cart for a SMALL site that stored all the information in a dataset stored in the session... but I've been told that isn't a good idea and reccomended I store the data in the sql database. so that's what I want to do!
I'm looking for resources that can help me get this started. These are the first questions I have about this approach, and any advice from you experts would be most appreciated!
1) do I store the data in a temporary table or do I use the regular table and make temporary rows? if the former how do I transfer the rows from the temp table to the order table? if the latter how do I change it from temporary to peromanent? in either case, how do I eliminate rows if the user abandons their cart?
2) how do I first initialize an order and keep track of the orderID for each user and ensure that no one is assigned a duplicate orderID?
those are my biggest confusions about this approach. I've looked for books on this but most are either too much about sql syntax and big-time server management, or they are too general and not specific to sql server. I've tried looking online, but I can't find much information on doing this using asp.net 2.0. thanks again for your help!
