I have a table defined as such:
PosterArtId int no 4 10 0 no (n/a) (n/a) NULL
Graphic image no 16 yes (n/a) (n/a) NULL
GraphicFilename varchar no 50 no no no SQL_Latin1_General_CP1_CI_AS
I have a Stored Procedure defined in the database that queries this table (joins with some other tables) that takes about 1 1/2 minutes to return results (running directly in query analyzer). The table itself has 8900 records and the resulting stored procedure returns 33 rows.
I have backed up this database and restored it to another database on a different machine also running SQL Server 2000. When I run the same stored procedure on this 2nd database (note the contents of the database and this table are exactly the same), it runs very quickly - in about 2 seconds.
I'm trying to figure out what is causing the query to run so slow on the original database, which is our production database server (note that none of the other queries seem to be running extra slow on this machine, just this particular one).
I've since been reading up on storing images in the database and I don't think the images are stored "text in row" - I ran the command: €œSELECT OBJECTPROPERTY(OBJECT_ID('tblPosterArt'),'TableTextInRowLimit')€? and got a 0 return value.
My ultimate goal is to figure out:
1) why the timing is so different on the two databases even though the have the same data
2) is there something we can do to speed up the results on our production server
For the first goal, I'm heading down the path that something in the database backup/restore did not recreate the btree storage of the image data in the same manner. Would this be correct? If not, is there some kind of analysis that I can do that will tell me some useful information?
I've run the Stored Procedure for both databases in query analyzer with the "show execution plan", "trace", and "statistics" turned on. In the Execution Plan of the production database I see a significant amount of time in three areas: Nested Loops/Left Semi Join, Clustered Index Scan, and Clustered Index Seek. But being as I'm not a dba (nor do we have one on staff), I'm not sure how to interpret this data. I keep wanting to point to some sort of environment issue since the data is the same between the two machines.
I suppose there is nothing to do about the 2nd goal without knowing why the query on the one machine is taking so long. Any thoughts on how to get more information here?
HiWe have a SQL server 2000 SP4 on a windows 2003 2x3Ghz XEON 4 GB ram.We have a table looking like this with currently 6 rows. Total data is aprox10 kb i all row all together.CREATE TABLE [dbo].[BIOMETRICPROFILE] ([BIOMETRICPROFILEID] [bigint] IDENTITY (1, 1) NOT NULL ,[FINGERPRINTTEMPLATE1] [image] NOT NULL ,[FINGERPRINTTEMPLATE2] [image] NOT NULL ,[FINGERPRINTTEMPLATE3] [image] NOT NULL ,[FINGERPRINTTEMPLATE4] [image] NOT NULL ,[FINGERPRINTTEMPLATE5] [image] NOT NULL ,[FINGERPRINTTEMPLATE6] [image] NOT NULL ,[TYPE] [nvarchar] (50) COLLATE Danish_Norwegian_CI_AS NOT NULL) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]GOselect * from BIOMETRICPROFILE takes ~4 seconds (!) to execute thourgh Queryanalyzer. Alle other tables has no performance problems.We have a SQL 2005 express instalation on the same server. If we restore abackup from the sql 2000 database the query takes aprox ~ 15 ms.What isgoing on here?Has SQL 2000 problems with image fields? or how can we find the problem?RegardsAnders
I have a table with two fields Part_num and Pic in SQL server 2000 Pic is of Image type. Is there a way I can save images for each part_num using Query analyzer?
Dear MS SQL Experts,I have to get the number of datasets within several tables in my MSSQL2000 SP4 database.Beyond these tables is one table with about 13 million entries.If I perform a "select count(*) from table" it takes about 1-2 min toperform that task.Since I know other databases like MySQL which take less than 1 sec forthe same taskI'm wondering whether I have a bug in my software or whether there areother mechanisms to get the number of datasets for tables or the numberof datasets within the whole database.Can you give me some hints ?Best regards,Daniel Wetzler

I am having performance issues on a SQL query in Access. My query isaccessing and joining several tables (one very large one). The tables arelinked ODBC. The client submits the query to the server, separated byseveral states. It appears the query is retrieving gigs of data from thetable and processing the joins on the client. Is there away to perform moreof the work on the server there by minimizing the amount of extraneous tabledata moving across the network and improving performance (woefully slowabout 6 hours)?
I have been using the report viewer to render my reports on a webpage. All worked fine for a time and now nothing is working correctly.
I have about ~8 report viewer on one page, all in an individual IFRAME. What happen is, sometimes I'm getting an error from IE (Internet Explorer cannot display the webpage) or the report starts loading (I see the title) but where the chart should be I have an X (broken image) icon.
Sometimes when I click on the image and choose "Display Image" the image will display.
Facts
Reports loads correctly on the report manager site (the Reporting Services webpage) Once those errors starts appearing, the session seems to act funny and I can't even refresh the webpage (F5) I have the latest report viewer patch installed I have the SP2 for SQL Server 2005 installed Running Windows 2000 Server Running IIS 6 The website was developped using IIS 5, but was tested on IIS 6 for about 3 weeks and we started to have problems today. The reports are linked with Analysis Services to get the data from cubes. I'm really out of ideas right now. Maybe I should just restart the IIS server, but the thing is live and I can't do it right now. However, if I need to restart it, will the problem occurs another time? Will it become a solution to restart the server?
I already restarted Reporting Services and nothing has changed.
I am able to run a query which runs FAst in QA but slow in theapplication.It takes about 16 m in QA but 1000 ms on theApplication.What I wanted to know is why would the query take a longtime in the application when it runs fast on SQL server?How should we try debugging it?Ajay
But now I am getting error "General Network Error. Check your network documentation" after specifying Use existing stored procedure in TableAdpater Configuration Wizard.
ALTER PROCEDURE dbo.Insert_MailSignature( @Singnature image )

INSERT INTO MailsSignature (Singnature) VALUES (@Singnature);
SELECT Id, Singnature FROM MailsSignature WHERE (Id = SCOPE_IDENTITY())
For testing I created a desktop application and found that the same Code, same(Use existing stored procedure in TableAdpater Configuration Wizard) and same stored procedure is working fine in inserting image into the table.
I have an update query running which to just now has been running for 22 hours running on two tables 1 a lookuptable that has just been created within the batch the other a denormalised table for doing data analysis on

any help in improving speed would be most welcome as there are 3 more of these updates to run right after this one and the analysis tables are almost double the size of this one
This sounds like a pretty easy one. I have a SQL 2000 database with 2-3.4GHZ CPUs and 1GB of RAM. I have one database on it. I go in Query Analyzer on another machine and run a simple query like 'SELECT * FROM USERS' which should return 15,000 rows.
IT takes 30 (thirty) seconds to finish this query. OMG
Where do I start to decipher why on Earth this takes more than .01 seconds?
Hi, I have a query which has suddenly started responding slow. CAn anyone tell me what could be the possibilities? I tried update stats(I am on sql 70-though it's done auto but i did it manually again) I used union all in place of union but had no big effect.any othe thought? Thanks!
I have a query that takes minutes to execute, even through there are about 300,000 records are being processed. I would appreciate any help with optimizing that query. I have two tables: User and Usage. Table user has two fields: User_Id and Date_Created and a non-clustered index on User_Id. Table usage has two fields also: User_Id and Date_Used and non-clustered index on both fields. The User table is populated when the user registers. The Usage table is populated every time the user opens a document.
Here is what I need to do: get the number of users from the Usage table who opened a document at least once after they have registered during the last 30 days for each day in the time frame, where the time frame varies. For example, if the time frame is 8/01/00 - 8/31/00, I need to get the following data:
date returns ---- ------- 8/01/00 10 (10 users returned to the document between 7/2/00 and 8/1/00) 8/02/00 15 (15 users returned between 7/3/00 and 8/02/00) . . . 8/31/00 20 (20 users returned between 8/1/00 and 8/31/00)
Here is my query:
SELECT [date], (SELECT count(distinct user_id) FROM usage u JOIN [user] ON u.[user_id] = [user].[user_id] WHERE u.[date] BETWEEN usage.[date]-30 AND usage.[date] AND u.[date]>[user].date_created GROUP BY usage.[date])returns FROM usage WHERE [date] BETWEEN @date1 AND @date2
This query works fine, but too slow. We use MS SQL server 7.0.
I have a query which responds immediately when run however if I add an order by clause it takes 40 seconds. Below is the query with the order by clause SELECT distinct Licenseplate, platetypecode.platetypecode, platetypecode.platetypecodeid FROM Ticket INNER JOIN PlateTypeCode ON PlateTypeCode.PlateTypeCodeID = Ticket.PlateTypeCodeID ORDER BY licenseplate
The Ticket table contains approx. 11,000 records. I have created a nonclustered index for the licenseplate field, a 7 char varchar field. Any suggestions for speeding up the query?
The following query is causing some problems because it's taking too long to complete. I looked at the estimated execturion plan and I am unsure why it appears to spend over 50% of its time doing a 'Bookmark Lookup' on on particular column (SRA_SR_ID in the S_EVT_ACT table). There is an index on the column - S_EVT_F14. I'm not sure if the query is using the index properly. What can be done to specifically improve this particular problem? In general, does anyone have some suggestions for optimizing the query as a whole?
Thanks in advance. Clive

I have a query that is taking too long to run. It take 14 seconds to return 6800 rows. However, if I move the query out of a stored proc, it takes 1 second. I want to understand this issue and ideally fix the stored proc case.
I've simplified my actual queries for readability.
-- @filter is value to filter against or NULL to return all records. CREATE PROCEDURE queryPlayerStations(@filter INTEGER) AS SELECT * FROM MyTable -- Other joins and query logic omitted for brevity WHERE ((@filter IS NULL) OR (MyTable.Column = @filter)) GO
When I run the query directly in Query Analyzer, it runs very fast.
DECLARE @filter INTEGER SET @filter = NULL
-- Takes ~1 second to return 6800 rows. That's great performance SELECT * FROM MyTable -- Other joins and query logic omitted for brevity WHERE ((@filter IS NULL) OR (MyTable.Column = @filter))
When I put the parameters in the stored proc it runs fast.
CREATE PROCEDURE queryPlayerStations AS DECLARE @filter INTEGER SET @filter = NULL
SELECT * FROM MyTable -- Other joins and query logic omitted for brevity WHERE ((@filter IS NULL) OR (MyTable.Column = @filter)) GO
-- Takes ~1 second to return 6800 rows. That's great performance EXEC dbo.queryPlayerStations
Anyone have any ideas what I can do to improve the stored proc case?

When I want to display the total records (#) in a webpage, it is very slow. When I try to remove the total records and show them per 20s, it responds very fast.
What might be going on here? The Query is against a single table withsome criteria. The database is active with upto 200 connected usersand at peak times there are 10 or more active sessions. Most of thetime, the query comes back in milliseconds. Occasionally though, it itcan take a whole minute. I've been watching CPU, Memory, Disk. Noneof these appear to be the bottlenecking. (CPU usually below 10% andalways below 50%, pages/sec is 0, and disk % is low and does notspikes during hangs) I also checked to see if hangs were synching withTlog backups or other scheduled jobs, but that is not the case. Thebox has good hardware 4GB RAM and 2 CPU at 3.4 GHz. What could beholding this query up?Thanks for any ideas.Dave

If the data type of field is "varchar",we can use "like" to query if it hassome substring.Such as "where custom.valuevariant like '%Verizon%' ", it will query out allrecords that contains string "Verizon".But how to do when data type of field custom.valuevariant is "image"?Thanks
Hi all.I want to use the following query in a sp to enable paging using ObjectDataSource.The problem (being EXTREMELEY slow) arises when I add these joins and where statements. SELECT r.RID AS ReqID, r.Name AS ReqName, r.Family AS ReqFamily,t3.Name AS DistName, t4.Name AS RurName,t5.Name AS VilName, n.Name+' '+n.Family AS NazerName ,ROW_NUMBER() over (order by r.Family) AS RowRankFROM Requests rLEFT OUTER JOIN Nazeran n ON r.nazerID = n.ID LEFT OUTER JOIN t1States t1 ON t1.ID = r.StateID LEFT OUTER JOIN t2Provinces t2 ON t1.ID = t2.StateID AND r.ProvID = t2.ID LEFT OUTER JOIN t3Districts t3 ON t2.ID = t3.provID AND t1.ID = t3.stateID AND r.DistID = t3.ID LEFT OUTER JOIN t4RuralDistricts t4 ON t3.ID = t4.distID AND t2.ID = t4.provID AND t1.ID = t4.stateID AND r.RurID = t4.ID LEFT OUTER JOIN t5Villages t5 ON t4.ID = t5.rurID AND t3.ID = t5.distID AND t2.ID = t5.provID AND t1.ID = t5.stateID AND r.VilID = t5.IDWHERE r.stateid=(case when @StateID is null or @StateID='' then r.stateid else @StateID end) and r.provid=(case when @provID is null or @provID='' then r.provid else @provID end) and r.rID=(case when @ReqID is null or @ReqID='' then r.rID else @ReqID end) and isnull(r.nazerID,'')=(case when @nazerID is null or @nazerID='' then isnull(r.nazerID,'') else @nazerID end) and r.name+' '+r.family like (case when @ReqName is null or @ReqName='' then r.name+' '+r.family else '%'+@ReqName+'%' end) **there are 1million rows in [Requests] table ,200000 rows in [t5villages], and about total 5000 rows in other tables.As you can see, this is for a GridView showing list of people requesting a loan allowing users to make alternative searches based on Name, Familyname ,ID ,... would you please help me optimize and make fast this query.Many thanks..
Hai i use Sql Server 2000 today i got this problem when i execute "select * from service_db" some times it is executed successfully but most of times the query on execution continusly why this happen how to solve this pbm very urgent
I have sql query to search for fields in a rather big view. If I execute the query in sql server enterprise manager, the results will be displayed in less than 6 seconds. However, if I execute it using asp.net, it will take very long (more than 2 minutes).
The query is a simple one like "SELECT * FROM myview WHERE name LIKE '%Microsoft%'". And the code I use to execute it in asp.net is
Dim dsRtn As DataSet Dim objConnection As OleDbConnection Try objConnection = GetOleDbConnection() objConnection.Open() Dim objDataAdapter As New OleDbDataAdapter(strSearch, objConnection) Dim objDataSet As New DataSet() objDataAdapter.Fill(objDataSet, strTableName) dsRtn = objDataSet Catch ex As Exception dsRtn = Nothing Finally If objConnection.State = ConnectionState.Open Then objConnection.Close() End If End Try
Where strSearch is the sql search string.
I don't have any problem using such code for other queries.
Could somebody suggest the cause of the problem and how to solve it? Thanks!
I am having a query where I am connecting to eight different tables using joins. When I join one table to another the speed of the execution becomes less. Even on my local server it is taking nearly 2 to 3 minutes to execute the query. How can I increase the speed of execution of my query.
This queries performance is acceptable (about 1 second) when run like this:
SELECT a.f1,a.f2,b.ff1,b.ff2 FROM table1 a LEFT OUTER JOIN table2 b ON a.id = b.id AND b.ff3 = 'T' WHERE a.mydate BETWEEN '3/4/2002' AND '3/6/2002' AND b.ff4 = 'somevalue'
It is terrible (60 seconds) when run like this: SELECT a.f1,a.f2,b.ff1,b.ff2 FROM table1 a LEFT OUTER JOIN table2 b ON a.id = b.id AND b.ff3 = 'T' WHERE b.mydate BETWEEN '3/4/2002' AND '3/6/2002' AND b.ff4 = 'somevalue'
I need the date range to come from the b.maydate. The field is indexed. If I run another query directy on table2 b without a JOIN and using b.mydate for some daterange it is quite fast. Any idea how to speed this up?
Please help me out: It is textremely slow when I run a query in My SQL Server 2000 Query Analyzer on my laptop. But when I turn off the wireless card on the laptop, the query runs instantly. Could you please tell me how can I make the server running faster when my computer is connected to the internet?
tblElements.ID is a foreign key to tblOwner.eID @PrevRec = dynamic number of previous records @owner = owner ID
SELECT TOP 2 tblOwner.eID FROM tblOwner LEFT JOIN tblElements ON tblElements.ID = tblOwner.eID WHERE tblOwner.own_ID = @Owner AND tblElements.ID NOT IN (SELECT TOP + @PrevRec + tblOwner.eID FROM tblOwner LEFT JOIN tblElements ON tblElements.ID = tblOwner.eID WHERE tblOwner.own_ID = @Owner) ORDER BY tblOwner.eID ASC
This query is used to display one record per page on a ASP paging script, I select top 2 because, I want to be able to know if I have another page or record to go to and deside if I need to display the "Next" button.
Also It is suppose to select records only assigned to it's ower. It works fairly quick when viewing first few hundred records, then it takes a very long time.
I have indexed ID and eID as clustered indexes also tblOwner could have multiple instances eID.
