Require To Optimize This Query To Remove Tomcats 'out Of Memory Error'
Jan 17, 2007
Hi i am using MS SQL 2000 db ,while executing following prepared statement query its working fine ...BUT when i remove "top 300" then tomcat giving OUT OF MEMORY ERROR!!
i think that its because of the cross join....So i want to optimize this query in such a way that it will not give "Out of memory error"
How can i re write this query?
Query :-
"select top 300 haw.DeviceID as deviceid,haw.Description as Description,haw.SerialNo as SerialNo,haw.Suffix as Suffix,haw.HWRev as HWRev,haw.Type as Type,dev.Status as Status from Hardware_PlaceHolder haw,Device_PlaceHolder dev ,Accounts ac where dev.siteId = ac.siteId and ac.CustID = ? ";
thanks in advance..

I am building a table change log that will track each attribute update and include the original and new values.
[BatchYearMonthKey] [int] NULL,
[BatchYearMonthDayKey] [int] NULL,
[AccountID] [varchar](200) NULL,
[Attribute] [varchar] (200) NULL,
[Old_ValueAtrDefault] [varchar] (200) NULL,
[New_ValueAtrDefault] [varchar] (200) NULL,
[Old_ValueAtrLong] [varchar] (max) NULL,
[New_ValueAtrLong] [varchar] (max) NULL
The challenge that the spectrum of varchar lengths across the table. I have one attribute that requires varchar(max) and all other attributes (about 40) are varchar (200).
I am trying to accomplish the following:
Account ID Status
1 Enabled
Now changed to
AccountID Status
1 Disabled
My log table will look like the following:
[BatchYearMonthKey] BatchYearMonthDayKey] [AccountID] [Attribute] [Old_ValueAtrDefault] [New_ValueAtrDefault] [Old_ValueAtrLong] [New_ValueAtrLong]
201504 20150409 1 Status Enabled Disabled NULL NULL
My question:
I created two fields (Old_ValueAtrLong and New_ValueAtrLong) dedicated for the one attribute that is a varchar (max). I was trying to avoid storing [Status] for example that's a varchar(200) in a field that is varchar(max). Is this the right approach? Or are there other recommendations in how to handle storing the data in the most efficient manner?

We're experiencing the following problem on our servers:
Server: Msg 701, Level 17, State 1, Line 3
There is insufficient system memory to run this query.
I've been able to fix the problem by a)Lowering the Max Server Memory and b)Minimum Query Memory.
However, Microsoft state there is a hot fix available for this issue at in KB Article 817262 (
http://support.microsoft.com/default.aspx?scid=kb;en-us;817262&Product=sql2k).
Any idea how one is supposed to contact Microsoft to get this fix without paying?
Thanks,
Nick

Hello,
We receive this error after running a complex query. Could someone please shed some light on what this means exactly?
One of our developer said we needed to purchase a server with more memory, but would SQL Server not simply just run slower by using virtual memory instead of physical RAM?
I know there is a limit and servers must be upgraded as the processing requirements increase, due to data set size increases for example, but we have just been told to "purchase more power because after a while as you process more rows, SQL Server will require more resources"
Any comments on this would be really appreciated.

I read this: [URL] ....
Which says you must drop the database to remove the filegroup.
I deleted all the objects and then backed up the DB and restored it and the filegroup is still there.
I was skeptical but some of the comments made me think this might work.
Do I really have to restore from a pre-memory optimized state?

Hello friends,
I’m facing performance related problem while running following query on SQL Server 2000.
This query is basically used to find last location of each unit that are passed. Here I am passing data like “‘26','27','28','29','30','31','32','33','34','35','36','37','38','39','40','41','42','43','44','45','46','47','48','49','50'" in @Units variable. But it takes too much time and I don’t get output. Table is having around 5 Million records.
Query:
SELECT Alias, tblUnit.UnitID, Location, Latitude, Longitude,Convert(varchar(10),UnitHistoryDate,1) + ' ' + substring(Convert(varchar(40),UnitHistoryDate,109),12,9) + ' ' + substring(Convert(varchar(40),UnitHistoryDate,109),25,2) as [Date/Time], unithistoryid
FROM tblUnit INNER JOIN
tblUnitHistory ON tblUnit.UnitID = tblUnitHistory.UnitID
WHERE tblUnitHistory.UnitHistoryDate
IN (SELECT MAX(UnitHistoryDate) FROM tblUnitHistory WHERE tblUnitHistory.UnitID in (' + @Units + ') GROUP BY tblUnitHistory.UnitID)
AND tblUnit.UnitID in (' + @Units + ')
ORDER BY tblUnit.UnitID
Table Structure:
UnitHistoryID int Primary Key
UnitID int
Location varchar(200)
Latitude decimal 9
Longitude decimal 9
Speed decimal 5
BatteryVoltage decimal 5
ReasonCode int
DistanceFromLastLocation decimal 9
UnitHistoryDate datetime
Indexes:
1. Clustered Index on Column UnitID
2. Non-clustered Index on Column UnitHistoryDate
3. Non-clustered Index on Column UnitHistoryID
Please help me to write optimize query and suggest me the steps to require making this query faster. Any help is appreciated. Thanks in advance.
Regards,
Sandeep

I have a nightly job that aggregates data into a summary table. Each night, an additional item may or may not be added, so the table is cleared and repopulated. I've got this working fine. Now, I am being asked to track when an item first appears in the summary table. Here is the code I am using to do this. I realize it is very poor performance, but I don't know how to make it better.
MyTable Columns: id INT PK ,v1 VARCHAR(4) ,v2 VARCHAR(10 ,v3 DECIMAL ,item1 BIT ,item2 BIT ,item3 BIT
MyTable2 Columns: v1 VARCHAR(4) ,v2 VARCHAR(10 ,v3 DECIMAL ,item INT ,FirstKnownDate DATETIME
All columns are NOT NULL.1 DECLARE @iNextRowID INT
2 ,@iCurrentRowID INT
3 ,@iLoopControl INT
4 ,@v1 VARCHAR(4)
5 ,@v2 VARCHAR(10)
6 ,@v3 DECIMAL
7
8 /* This is a loop that executes for a dynamic number of items, eg item1=1, then item2=1, etc */
9 SET @iLoopControl=1
10 SELECT @iNextRowID=MIN(id) FROM MyTable WHERE item1=1
11
12 IF ISNULL(@iNextRowID,0) <> 0 BEGIN
13 SELECT @iCurrentRowID = id
14 ,@v1 = v1
15 ,@v2 = v2
16 ,@v3 = v3
17 FROM MyTable
18 WHERE id=@iNextRowID
19
20 WHILE @iLoopControl = 1 BEGIN
21 IF NOT EXISTS(SELECT * FROM MyTable2 WHERE v1=@v2 AND v2=@v2 AND v3=@v3 AND item=1) BEGIN
22 INSERT INTO MyTable2
23 /* COLUMN */ (v1,v2,v3,item,firstknowndate)
24 SELECT @v1, @v2, @v3, 1, GETDATE()
25 END
26
27 SELECT @iNextRowID = NULL
28 SELECT @iNextRowID = MIN(id) FROM MyTable WHERE id>@iCurrentRowID AND item1=1
29
30 IF ISNULL(@iNextRowID,0) = 0 BEGIN
31 BREAK
32 END
33
34 SELECT @iCurrentRowID = id
35 ,@v1 = v1
36 ,@v2 = v2
37 ,@v3 = v3
38 FROM MyTable
39 WHERE id=@iNextRowID
40 END
41 END42 /* This is the end of the items loop */
This query takes 5 minutes to do straight inserts without the test for exists in the loop for 3 items. MyTable has just under 96,000 rows in it. MyTable2 has 121,857 rows in it. It is not about 55 minutes and it is still running with the exists so that a row isn't inserted twice. Is there anything I can do to optimize this? EDIT: The query just finished running again with the test for exists on each row. It shouldn't have inserted any new rows, but it took 57 minutes and inserted another 114,115 rows. Not good. Anyone see what is wrong with the query?

Hi all,
I need help to optimize this query:
Code:

t.datum<'2005-01-01' AND
(t.uplata='S' or t.uplata='U')
GROUP BY t.temeljnica, t.rbr
HAVING
abs(sum(t.duguje-t.potrazuje))<>abs(s.saldo))
ORDER BY

Currently this query takes forever to execute. Any suggestions appreciated.

Can someone look at this sql statement and tell me if it can be sped up? Also I have to add to it by joining it with another table. How do I do that? Just by nesting another join?
Thanks!
Set rs=Server.CreateObject("ADODB.Recordset")
sql = "SELECT td.TeamID, td.TeamName, rt.PartID, rt.Effort, rt.UnitMeas, pd.MinMilesConv "
sql = sql & "FROM TeamData td INNER JOIN PartData pd ON td.TeamID = pd.TeamID "
sql = sql & "JOIN RunTrng rt ON pd.PartID = rt.PartID "
sql = sql & "WHERE rt.TrngDate >= '" & Session("beg_date") & "' AND rt.TrngDate < '" & Session("end_date")
sql = sql & "' AND pd.Archive = 'N' AND pd.Gender = '" & sGender & "' AND pd.Grade >= " & iMinGrade
sql = sql & " AND pd.Grade <= " & iMaxGrade & " ORDER BY td.TeamID"

ORDER BY Cert_WarehouseDetails.RecordNO
In above query,as
1. Union (INNER) query returns me 200000 records.
2. If I run above query it takes 18 sec because no index on Cert_WarehouseDetails.RecordNO and i'm ordering on that.
3. When I avoid to 'ORDER BY Cert_WarehouseDetails.RecordNO' then query takes 2 sec.
4. In this case Do I have to use 'nvarchar'
convert(datetime,convert(nvarchar,Cert_WarehouseDe tails.IssuedDateX,101)) <= '3/31/2004')
5. Why do we have to use 'nvarchar' can you explain to me in above statement..
Can you provide me alternate solution so I can make it fast.
Please reply to me asap. Thanks in advance.

M. Jain

Hello,I am trying to find all records that have matching detail_1 or detail_2columns. This is what I have now:select t1.id, t1.detail_1, t1.detail_2, t2.id from user_details t1,user_details t2where t1.detail_1 = t2.detail_1 or t1.detail_2 = t2.detail_2;Using smaller tables of around 1000 records, I have verified that thisindeed does the job. However, when I apply it to the real table thathas around 40,000 records, it takes so long that I have to stop thequery.The table in question is quite simple and is created as follows. Thereare no indexes on the table:create table user_details (id integer, detail_1 varchar(50), detail_2varchar(50)Is there a way to make it go faster?

Hello all!
I've currently got a query that takes two tables with the same structure, and spits out the differences in the second table - this is done to help me see what new records have been added in the second table that don't exist in the first. The only catch is that I have to compare two columns in sort of a pseudo-composite-key. Here's the gist of the table structure:
Table A:
ID (Autonumber),
Firstname,
Lastname,
OS,
PC Manufacturer
Table B (The new one):
Firstname,
Lastname,
OS,
PC Manufacturer
The two columns I have to compare are firstname and lastname, as there aren't any other unique identifiers that match between the two tables. Right now, I'm using some really convoluted WHERE statements, and I suspect that it could be done more cleanly. Does anyone have any suggestions?
Thanks in advance...

The result shows fields such as Bid_Price_Best_Latest and Ask_Price_Best_Latest may or may not have null values.
At present, I use a cursor to get the values of these two fields if any of them is null from the table tblPricesSourcesImportHistory for the latest Import_Date on each record.
These two fields are referred to as Bid_Price, Ask_Price in tblPricesSourcesImportHistory.
Now I would like to find out how to do this without the use of a cursor, so that I can speed up this query.
Thanks

I have a Stored Procedure I am trying to run that joins to a remote database. I am able to see everything in the QA just fine with this (courtesy of Anatha):
SELECT DISTINCT a.*
FROM LOCATION a,
LinkServer.MC_Card.webuser.LOCATION b
WHERE a.location_number = b.location_number
But I am trying to run this query in Stored Procedure(notice the 4-part name callout to the LinkedServer tables) which returns the error message:
Error 7405: Heterogeneous queries require ANSI_NULLS and ANSI_WARNINGS options to be set for the connection. This ensures consistent query semantics. Enable these options and then reissue your query.
Here is the Stored Procedure:
/****** Object: Stored Procedure dbo.spELRMCcardXtionByDate
Script Date: 4/24/2001 11:51:27 AM ******/
CREATE PROCEDURE dbo.spELRMCcardXtionByDate @dcid nvarchar(255), @startDate datetime, @endDate datetime
AS
-- declare @dcid nvarchar(255)
-- set @dcid = '1032'
SELECT STORE.[Str#], STORE.[Dcid#], E.card_number, E.program_number
, E.start_date, E.end_date, E.card_number, E.event_number
, E.status, E.budget, E.scheduled_date, P.tx_time, P.purchase_amount
, L.merchant_name
FROM (STORE INNER JOIN LinkServer.MC_Card.webuser.EVENT E ON STORE.[DemoID#] = E.event_number)
LEFT JOIN (LinkServer.MC_Card.webuser.LOCATION L RIGHT JOIN LinkServer.MC_Card.webuser.POS_TX P ON L.location_number = P.location_number)
ON E.event_number = P.event_number
WHERE (((STORE.[Dcid#])= @dcid)) AND E.scheduled_date BETWEEN @startDate AND @endDate
ORDER BY STORE.[Str#]
-- and E.card_number IS NOT NULL
GO
Any help greatly appreciated.
Thanks,
Bruce

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.

Hell All,
Following query takes 7 minutes to execute while using search criteria as shown below in blue text(ie. IN(2006,2007)
if criteria changes to =2006 as shown in 2),this takes 2minutes
But I want expected output as in query 1) in less time.
How to optimize following query for execution time?

create index i1 on t1(a)
create index i2 on t1(b)
create view v1
as
select * from t1 where isnull(a,b) = 'test'
select * from v1
The above SQL "select * from v1" is doing a table scan.
What do I do to make it perform an index seek ????
