Very Slow Query When Using In Keyword
Aug 12, 2007
hey guys
i have a query that takes too long that, actually i never got it to finish excuting
the query looks like tht
select referer,count(*) from t1 where referer is not null
and referer in( select distinct(Referer_Direct) from t2 where Referer_Direct is not null )group by referer
the inner select just returns 5 rows
so when i replace the inner select with actual values like tht
select referer,count(*) from t1 where referer is not null
and referer in('val1','val2','val3','val4','val5' )group by referer
it excutes immediatly
any clues how to solve this issue
the db is running on sql server 2005 express SP2
thx in advance

I have a sample photo database where we have added keywords to search for photos. I wanted a way to list all of the keywords that are in the database individually. The problem is in my keyword field there are many keywords seperated by a comma.
Ex: "bull, barrel, rodeo, western, cowboy" would in the keyword field for one photo.
I wanted to select distinct all of the individual words from each keyword field in all of the records.
Can this be done? What would the query look like?
I am looking for a list like:
bull
barrel
rodeo
western
cowboy
Any suggestions?
Thanks,
Rob

Hi all,I have two tables:workgroups (wg_id, wg_name)workgroups_keywords (wgk_wg_id, wgk_keyword)Each workgroup has an associated list of one or more keywords.What I want do to at first was given a particular list of keywordsbring back a list of workgroups that have at least one matching keywordassociated with it.I have the following query:select distinct(wg_id), wg_namefrom workgroups, workgroups_keywordswherewgk_keyword in (#QuotedValueList(Keywords.wgk_keyword)#)andwg_id = wgk_wg_idorder by wg_nameThis works great.However, is there a way in a single query to order the returned rows bythe number of keywords that are found to be matching (in other words anorder by relevancy, the more keywords that match the more relevant thereturned row)?Thanks in advance.David

hi
I am having trouble with the following query within my store procedure.
as you can see, i am making an union of 2 separate queries.
in the 2nd part of the union, i encounter a column in the database where the column name is the same as the keyword "desc"
is there a way which i can get around this, or is there any other way that i can sepecify the column? (excluding the possibility of using *)
CREATE PROCEDURE topcat.getTransHistory
(
@contact_id numeric(9)
)
AS
BEGIN
DECLARE @phone_no varchar(255)
set @phone_no = (select top 1 phone_num from topcat.class_contact where _id = @contact_id)
select cast(trans_new.trans_date as varchar(50)) date,
'' code,
cast(payment.date_paid as varchar(50)) datepaid,
'' "desc",
case payment.payment_type
when 'cheque' then trans_new.item_total
else ''
end pledged,
'' mail,
case payment.payment_type
when 'cheque' then ''
else trans_new.item_total
end received,
'' receipt
from topcat.class_transaction trans_new left outer join topcat.class_payment payment on trans_new._id = payment.transaction_id
where trans_new.contact_id = @contact_id
union
select cast(trans_old.date as varchar(50)) "date",
trans_old.code,
cast(trans_old.datepaid as varchar(50)) "datepaid",
trans_old.desc,
cast(trans_old.pledged as varchar(128)),
trans_old.mail,
cast(trans_old.received as varchar(128)),
trans_old.receipt
from topcat.MMTRANS$ trans_old
where phone = @phone_no
END
GO
Cheers

In Query Editor I type statements like this:
"select * from ...."
Does Query Editor support a "macro" facility where I could, via keystorke, uppercase all t-sql keywords? (so it would look like SELECT * FROM...)
TIA,

P.S. You think I'm lazy? I knew a programmer who was so lazy that his password was one character long!

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 =

from Combined_Admissions
where ((Combined_Admissions.NHSNumber = Provider_APC_2004_05.NHSNumber) or

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?
Thanks.

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

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
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?

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

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?

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

Is there a more efficient way to write this query? It takes 2 minutes and 15 seconds to run against 200,000 records.
UPDATE Tbl_a
SET Flag = NULL
WHERE Flag = 1 And Not Exists(Select Id From Upload
Where Tbl_a.Id = Upload.Id)
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..

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

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

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

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.

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"));

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
