Very Slow Running Update Query Query

Nov 19, 2004

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

the query thats causing teh problem is


--//////////////////////////////////// this is the one thats running


Print 'Update Provider 04-05 EmAdmsCount12mths : ' + CAST(GETDATE() AS varchar)
GO
Update Provider_APC_2004_05
set EmAdmsCount12mths =
(Select COUNT(*)-1
from Combined_Admissions
where ((Combined_Admissions.NHSNumber = Provider_APC_2004_05.NHSNumber) or
(Combined_Admissions.PASNUMBER = Provider_APC_2004_05.PDDISTNO)) and
(Combined_Admissions.AdmDate BETWEEN DateAdd(yyyy,-1,Provider_APC_2004_05.AdmDate) AND Provider_APC_2004_05.AdmDate) AND
Combined_Admissions.AdmMethod like 'Emergency%')-- and
-- CA.NHSorPrivate = 'NHS'))
FROM Provider_APC_2004_05, Combined_Admissions


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

VERY Slow SQL Query

Mar 8, 2007

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?
 
Thanks.

A Very Slow Query

Oct 12, 2000

Hi,

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.

Thank you,
Yana

Slow Query

Dec 2, 2002

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?

Oh So Slow Query...

Jun 15, 2004

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

Help Fix Slow Query.

Oct 12, 2006

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

DECLARE @filter INTEGER
SET @filter = NULL

-- Takes 14 seconds to return 6800 rows. That's unacceptable performance
EXEC dbo.queryPlayerStations @filter


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?

Very Very Slow Query

Mar 27, 2008

Hi guys/gals

I have only just signed up, as I have a problem thats confusing me a lot

I have a page (classic asp - sadly) that displays a list of invoices for a certain customer

Each of these customers has fairly complex permissions system, but the page generates a list of invoices and values in 0.01 seconds

However in the while...do loop, for each invoice it checks a database table for "extra charges"..

This is a simple SQL query

"Select Sum(amount) from extra_charges where invoice_number=" & current_invoice_number

However each time it runs this simple select statement it takes 2 seconds - which causes the page to load in 70 seconds instead of 0.01

I am absolutely beyond confused. I have tried it in a stored procedure, and a direct ado query..

The table by the way is empty on my current test system, and one one other system has about 150 records in it. Both take the same time

Any help would be appreciated?

This is a MSSQL 2000 database I've inherited, I am usually a PHP/MYSQL developer - so im a little out of my field of expertise here

AND (REPLACE(addr.Postcode, ' ', '') LIKE @Postcode + '%')
AND c.DateArchived IS NULL

here all fields @CLI, @Surname, @Address, @Postcode are varhcar types...which is making this query very slow...is there any suggestion to improve this query?

Query Is Slow Sometimes

Sep 13, 2006

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

Sql Query Execution Using Asp.net Became Very Slow

Dec 2, 2003

Hi all,

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!

Best regards,
David

Execution Of Query Is Very Slow

Jul 1, 2004

Hi,

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.

Thanks in advance,
Uday

Slow JOIN Query

Mar 6, 2002

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?

Thanks,Adrian

How To Optimize This Slow Query?

Mar 25, 2004

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.

Is there an easier way of writing this out.

Slow Query Due To Criteria

Jan 24, 2008

I have a query in access that is running extremely slow and I'm trying to find a better way to write it. It appears to be the criteria statement that is causing the lag. Is there a better way to write this? And unfortunately I have to keep it in access.

query:
SELECT DISTINCT "JBC" AS ClientCode, PaymentDetail.PatientNumber, Procedures.CaseNumber, IIf(IsNull([TicketNumber]),Procedures.patientnumber & Year(Procedures.dateofservice) & Month(Procedures.dateofservice) & Day(Procedures.dateofservice),Procedures.ticketnumber) AS ClaimNumber, PaymentDetail.PaymentCounter, PaymentDetail.TransAmount, Payments.PaymentDate, PaymentDetail.AccountingDate, PaymentDetail.TransDate, payments.PaymentType & "-" & Adjustments.adjustmentcode AS CombinedPmtType, Payments.PaymentType, Payments.PaymentCode, Adjustments.AdjustmentCode, PaymentCodes.BriefDescription, PaymentCodes.LongDescription, Payments.CarrierCode, Payments.Remarks, Procedures.ProcedureCode, Procedures.DateOfService, PaymentDetail.DetailCounter
FROM ((((PaymentDetail LEFT JOIN Procedures ON (PaymentDetail.PaymentCounter = Procedures.Counter) AND (PaymentDetail.AccountingDate = Procedures.AccountingDate) AND (PaymentDetail.PatientNumber = Procedures.PatientNumber)) LEFT JOIN Payments ON (PaymentDetail.TransDate = Payments.AccountingDate) AND (PaymentDetail.TransCounter = Payments.Counter) AND (PaymentDetail.PatientNumber = Payments.PatientNumber)) LEFT JOIN PaymentCodes ON Payments.PaymentCode = PaymentCodes.PaymentCode) LEFT JOIN Adjustments ON (PaymentDetail.TransDate = Adjustments.AccountingDate) AND (PaymentDetail.PatientNumber = Adjustments.PatientNumber)) LEFT JOIN AdjustmentCodes ON Adjustments.AdjustmentCode = AdjustmentCodes.AdjustmentCode
WHERE (((Procedures.CaseNumber)=0) AND ((PaymentDetail.TransAmount)<>0) AND ((Payments.PaymentType) Is Null) AND ((PaymentDetail.DetailCounter)=2)) OR (((Procedures.CaseNumber)=0) AND ((PaymentDetail.TransAmount)<>0) AND ((Payments.PaymentType) Is Null) AND ((PaymentDetail.DetailCounter)=5) AND ((AdjustmentCodes.InsuranceIndicator)="N"));

Slow Query When You Add An Order By

Feb 20, 2008

SELECT Column1,Column2,Column3 ....
FROM vwMyView
ORDER BY CreatedDT

View has about 10000 rows, If I remove order by query runs faster but adding an order by cause query to timeout..

All tables have clustered index based on the primary key of the table..

(a) Should I create an index view with CreatedDT as non clustered index?
(b) Or create a non clustered index on CreatedDT column on the underlying table?

I can provide DDL but if something obvious I am missing

Thanks

Query Is Slow On My Db But Not Copy

Mar 2, 2008

I have a query that is taking 6 mintues on my db so i copied the 2 relevant tables to a new db for testing and then tested the query and it took only 30 seconds.

why would this be? tables are the same size - i copied to the new by creating the table and then inserting from the old to then new.
these are very big tables.

the first db does have many other tables but why should that make a difference?

Why Is SQL Query Slow On On Server But Not Another

Mar 18, 2008

Hi

I have a database and when I run a query on it the query takes 10 minutes to complete. I am running the following query

SELECT t103.cs_flag, t103.pr_flag, SUM (t103.amount), COUNT (t103.record_id)
FROM br_data t103
WHERE t103.acct_id = 12 AND (t103.state = 3 OR t103.state = 7)
GROUP BY t103.cs_flag, t103.pr_flag

The br_data table doesnt seem to be using its indexes ?? And it has around a million records. Now when I export the database and import on to another SQL server and then run the same query as above it only takes 1 or 2 seconds.

On the server that we are having problems with I have tried to re-build the indexes using DBCC DBREINDEX (br_data,' ',0) but this hasnt helped. I have also tried backing up the database, delete the database then restore, this also hasnt helped. I have no idea why the query runs slow on the original box, but then quick when I transfer it to another server??

Both servers are running windows 2003 with SQL 2000 SP4. There are no resorrce problems such as CPU / memory, Any ideas??

Thanks

Slow Query With Date

Jul 23, 2005

Hello EverybodyI run the following query against to identical databases. Executiontime on the first DB is 0 seconds, on the other 6 seconds!SELECT dbo.HRMABZ.EMPKEY , dbo.HRMABZ.CONNUMB, dbo.HRM_CALENDER.Datum, dbo.HRMABZ.ABZTXTFROM dbo.HRM_CALENDER INNER JOIN dbo.HRMABZON dbo.HRM_CALENDER.Datum >= dbo.HRMABZ.ABZDATFAND dbo.HRM_CALENDER.Datum <= dbo.HRMABZ.ABZDATTWHERE (dbo.HRMABZ.ABZTECH = 'N')AND (dbo.HRMABZ.ABZLDLT = 'N')AND (dbo.HRM_CALENDER.Valid = 1)I tried to analyze to query execution in the execution plan and foundtwo different arguments in a 'nested loop / inner join' which I dontunderstand. The nested loop does consume most of the time:On the fast Server the argument says:'Outer References:([HRMABZ].[ABZDATT],[HRMABZ].[ABZDATF])'On the slow server the argument says:'WHERE: ([HRM_Calender].[Datum]>=[HRMABZ].[ABZDATF] AND[HRM_Calender].[]<=[HRMABZ].[ABZDATT])'Additional information for the two databases:- Slow database runs on a SQL2000 SP3a English, W2K SP3- Fast database runs on a SQL2000 SP3a German, W2k SP3Can somebody explain me the difference between the two execution plansand how I could force the slow database acting the same way as thefast one does?Thank youThomi

4 Part Name Query Very Slow

Nov 5, 2007

exec sp_tables_ex 'linked server'


The table_cat returned a null value. I ended up writing

select * from linked_server..schema.table and it did work. However, it was really slow. 56 seconds vs. less than a second for the pass through openquery.


My guess is that the problem is that the table_cat was null and this is why it is so slow. Is this correct? How do I resolve this speed issue?

Strange Slow Query

Mar 26, 2007

Hi all,

Last week we've made some modifications to our 20 GB database(with 2 huge tables (around 30 million rows)):
1.
we've created 8 filegroups on 8 physical disks with RAID 1+0. In each
of them we have one big table and others small tables unrelated with
the big table. We've also created a filegroup for the nonclustered
indexes from those big tables.
2. The Server is running SQL Server 2000 with SP3a
3. We've reindexed the database, updated statistics on all tables
Now, we have a SP that on the old configuration took about 20 min to complete.
But now, on our new configuration with the modifications listed above it's taking about
3 HOURS.
This is the SP's body: is calling a function:
create proc X
as
begin
Select dbo.myfunc(mytable.field)
from mytable
end

The function used in select statement is querying those 2 huge tables.

If the select statement is runned for only one record it's done instantly, but for 20000 recs it is taking almost 3 hours.
I must specify that also the function is running instantly, but in that select statement something is happening and we don't know what!!!

If you have any ideeas on what to do or what to check
Thanks a lot
Dan

Compact 3.5 Slow Query

Dec 19, 2007


I've got a slow query that when run in management studio again the publisher database it completes in 2 seconds but when run on a compact 3.5 sdf it takes 5-10 minutes. After adding some indexes it gets down to 5 minutes at best. The complex explicit joins requiring both null or equal are required for the propper results.

Any suggestions would be appreciated.

Thanks,

Patrick
