I am not sure if I am in the correct location or if I should be in the SQL forum but here is my question:
I have an update statement that goes out through SQL 2000 through a local linked server to another SQL 2000 server on my machine. When I run the update in Query Analyzer it takes less than a second. When I run it in my C# code using the SqlCommand object and parameters it takes me ~23 seconds. If I remove one of the parameters it goes down to ~15 milliseconds. Has anyone heard of this happening?
The parameter that I remove is a simple char(10) column that isn't the primary key and is used in the WHERE statement. There isn't an index on the field.
23 Seconds
Update table Set column = @val WHERE field = @field AND other = @other
15 milliseconds
Update table Set column = @val WHERE field = 'values' AND other = @other
i have an aplication with any problems, the aplication is hang and in the log is
SQL Server has encountered 1 occurrence(s) of IO requests taking longer than 15 seconds to complete on file [d:Program FilesMicrosoft SQL ServerMSSQLdata empdb.mdf] in database [tempdb] (2). The OS file handle is 0x000003DC. The offset of the latest long IO is: 0x00000016930000 and the aplication log is

I see the following error on the sql server log of one of our sql servers running sql 2000 with sp4. SQL Server has encountered 1964 occurrence(s) of IO requests taking longer than 15 seconds to complete on file [h: empdb.mdf] in database [tempdb] (2). The OS file handle is 0x00000534. The offset of the latest long IO is: 0x0000002b09e000
Any idea as to what might be causing this error. Appreciate any comments.
I have a Stored Procedure that has a query in it and it take 0 second and then a stored procedure that takes 16 seconds. From what I can tell they shoul be the same.
It doesn't recompile when i run the stored procedure, I checked that.
I have a simple update/initialization query (set integer column = 0 on all rows) that's been running for over 28 hours. There are just over 27 million rows in the table. In current activity it shows that the transaction is open but it's sleeping, and in locks it shows 1 DB S mode lock, 766 page X mode locks, 1 page U mode lock, and one table X mode lock. Server is 7.0 with 1.7 gig ram. Anyone have any ideas as to why it's taking so long? Table is about 7 gig in size; can't get to it in Enterprise Manager without locking it up...
Hi, I have a table with 48 million rows,when i executed following update query it is taking 10 HOURS in SQL SERVER 2000 with SP1. Where as when i executed same query in SQL SERVER7.0 with same table then it is taking 13 MINUTES. Comming to Machine...SQL 2000 Server has more processors and greater memory than SQL 7.0 m/c. It looks strange but this is true.Does any one faced such problem..is there any bug in SQL 2000?????
Here is Query::
update cus_pay_jan_dist set univ_regdate = b.dayid from cus_pay_jan_dist a with (nolock), tm_dayids b with (nolock) where a.univ_regdate = b.dayidnum and a.univ_regdate like '2001%'
I have an update statment in my SSIS that use to take 10 minutes in SQL 2000 dts and now its take 1 hour 15 minutes in SQL 2005.

It is using ole db connection. About 36,000 records that it is updating.
I have read ole db can be slow and to use staging table. Does that mean on all updates like this I have to use a staging table and then insert. I didn't use to have to do this in SQL 2000. Has it changed. Are there any other options?
I'm using a OLE DB COMMAND component to perform an update (SQL statement) but the procces takes about 9 hours, so I changed it to a stored procedure but it was the same, I need to update about a a million of rows and the package is very simple.
How can I improve the time, Can I use another component or startegy?
Hi all.If I've got a query which has a field with seconds in it... how will I usethe Convert function to get my field converted to the format: HH:MM:SS ?The field with the seconds in is called: "Diff"Thanks alotRudi

Here is the situation:
We have a server running nicely for the past 1 years. And just yesterday, things started to acting very slow. A simple query that will return one row:
"select * from product where itemno = 1234 and visible =1"
will take 20 second sometime 30! The weird thing is.. it only happens intermittently. The table also only contain 4000 rows. so its not even a big table. I am not sure if this is caused by lack of memory or what (256mb ram, p4 1ghz on this server).
The system cpu usage % avg around 3-8%. but when that weird behavior started. All the other queries will wait for it to finished and then burst the cpu usage up to 100%. Afterward, it will level off and then the cycle repeat again.
I'm just hoping if anyone can give me a few pointers as of where to troubleshoot. I've tried rebuild the index on that table but it didn't help. This weird behavior not only happen on this particular table, but also on different db within the same server. (note: they are small dbs only)
p.s. here is the site that is running on this db, you'll see this weird delay after a few click on the pages. http://www.animepot.com
This is in ASP.NET 1.1. I have a performance problem with a webform. The form contains several bound fields and a couple datagrids. I fill the grids by creating a data adapter, then I use the adapter to fill a dataset, then I set the grid datasource to the dataset. The query to fill one of the grids is getting a SQL timeout when running from my application (it takes about 40 seconds to complete). When I run the same SQL code from SQL Query Analyzer it runs in less than 1 second. (it is embedded sql in the app, not a stored procedure). I suspect that something else is being requested from SQL during the postback that is causing a blocking issue or something but I can't tell exactly what is happening. I've tried tracing through the code and all that I can tell is that the timeout occurs during the dataadapter.fill command. Has anyone else seen something similar? Is there a good way for me to see what SQL commands are being executed from ASP.NET? Any advice on debugging this would be much appreciated.

Below is my query which is taking a long time to execute, DB is SQL Server 2005 through a web Application I have downloaded the latest MS SQL 2005 driver 1.xxx and still the query takes long to execute
The Description field is a Full_text indexed catalog column the p.vendornumber is a primary key same with c.ID
Any one have an idea why it is taking this long to run
The Execution Time is: 13640 ms Which I think is very long
SELECT Upper(p.Type) Type,p.Modelname,p.partno,Upper(p.description) description, Upper(p.classification)classification,p.vendornumber,p.mfg, p.price,c.CompanyName,c.City,c.State,p.thumbnail FROM P_all p, Acts c WHERE p.vendornumber = c.ID AND CONTAINS(p.Description, '"helmet*"') Order by p.VendorNumber
dear guys. i have this one problem, where the sql statements really took very long time to be processed. It took more than 1 minute, depending on the total data in the table. I guest this have to do with the 'count' statements. here is the code:
------------------------------------------------------------ $sql = "SELECT company,theID,abbs,A as Active,N as Nonactive,(A+N) as Total FROM( select distinct D.nama As company, C.domID As theID, D.abbrew As abbs, count(distinct case when B.ids is NOT NULL THEN A.dauserid END) As A, count(distinct case when B.ids is NULL THEN A.dauserid END) As N FROM tableuser A LEFT OUTER JOIN tabletranscript B on (A.dauserid=B.dauserid) INNER JOIN thedommember C ON(C.entitybuktiID=1 AND C.mypriority=1 AND
C.entitybuktiID=A.dauserid) INNER JOIN mydomain D ON (C.domID=".$getID.") GROUP BY D.nama, C.domID, D.abbrew ORDER BY company )";
Hope any of you can simplify this statements into a query that doesnt take ages to be processed.
I'm running a query (see below) on my development server and its taking around 45 seconds. It hosts 18 user databases ranging from 3 MB to 400 MB. The production server, which is very similar but with only 1 25 MB user database, runs the query in less than 1 second. Both servers have been running on VMWare for almost 1 year with no problems. However last week I applied SP 2 to the development server, and yesterday I applied Critical Update KB934458. The production server is still running SQL Server 2005 Standard SP 1. Other than that, both servers are identical and running Windows 2003 Server Standard SP 1. I'm not seeing this discrepancy with other queries running against user databases.

I have a sql snippet from a 3rd party application that will not complete its transaction. The SELECT statement executes but does not finish. Instead the statement just sits in AWAITING COMMAND for 1000 seconds then dies, thus killing the UPDATE statement that is supposed to follow.
Can€™t understand the Query execution interval, for every one criteria it takes extra 60 seconds. Help please?,

I have one stored procedure and its taking 10 mins to execute. My stored procedure has 7 input parameters and one temp table( I am getting the data into temp table by using the input parameters) and also I used SET NOCOUNT ON. But if copy the whole code of the SP and execute that as regular sql statement in my query analyzer I am getting the result in 4 seconds. I am really puzzled with this.
What could be the reason why the SP is taking more than query,Unfortunately I can't post the code here.
Hope someone can help me with this because its driving me potty!
I have a .NET script that sends really simple queries to SQL server that works perfectly 50% of the time but for the other 50% it takes ages (2-3 minutes) and then fails, I'm assuming because it times out. I then check the SQL by excecuting it via query analyzer and it again takes ages but will work eventually (I'm assuming because this bypasses the timeout settings, but changing these isn't on).
This happens randomly, the scripts will be working fine and then fail a few times before magically working again!
Any ideas? Perhaps some database features that commonly cause this problem? The problem only occurs with one database, all our others are fine but we can't spot any differences!
Hey all, i'm making the pages meta keywords on my site dynamic, and i was wondering is there is a string, for example "Dell 17" Monitor Brand New", that would split it into each word for the meta keywords. example "Dell, 17", Monitor, Brand, New" (and possibly to not put a comma on the last word?)
Hello to all, I have a stored procedure. If i give this command exce ShortestPath 3418, '4125', 5 in a script and excute it.

I'm looking for a query that can "batch" update one table from another. For example, say there are fields on both tables like this: KeyField Value1 Value2 Value3 The two tables will match on "KeyField". I would like to write one SQL query that will update the "Value" fields in Table1 with the data from Table2 when there is a match.
