Starting with a SQL Server 2000 database, my company built a new server with SQL Server 2005 and restored the SS2000 database from backups. We're now seeing some extreme issues where queries that took 30 seconds now take 3 minutes. Would this make you suspect index issues? Any recommendations on diagnosing and fixing this would be appreciated.

I am unable to migrate any DTS packages, from a SQL Server 2000 package, from a structured storage file, or from a DTS package imported into SQL2005 (Developer Edition, 32 bit). Running the Package Migration Wizard, every time I get to the List Package screen, i get the error below. I haven't found any other mention of this so far. Anyone else seen this error or have suggestions?

Hi Guru,After spening quite sometimes to watch my box, I've seen PAGEIOLATCH isa lead blocker in my SQL Server 2000 server. Below is the detailed:SPID lastwaittype waitresource blocked status cmd57 LCK_M_S KEY: 7:963690681:8 65 sleeping execute65 PAGEIOLATCH_SH 7:1:217904 0 sleeping selectI thought, latching should be very short-term synchronization. Fromsystemprocess table, I saw the latch waited in a minute sleepingwithout doing any work.My database is about 23GB and more than 5000 tables. The RAID subsystemis RAID1 with 1 disk mapped to C and D logically. Data files and tempdbfiles are located in one location. Tranlog file and log backup filesare located in the same location with different disk spindle.Currently, we are experiencing very slowness and IO bound. I'm ready torebuild the server by putting the RAID10 and 1 and distributingmultiple data files to different RAID10 and tempdb and log files toRAID1.Other than this, how to minimize the IO latch contention?Thanks so much,Silaphet,
View 1 Replies View RelatedHi guys,
Do you have any stored procs or utility to track down the lead blocker as well as the blocked processes on SQL Server 2000? Similar to a tree structure with the lead blocker on top followed by the processes being blocked by the lead blocker.
Thank you very much.

We have accounts that pay for a particular "premium" service. It's entirely possible an account paid for this service for three consecutive months in 2013, then stopped paying, then started paying again. Why I'm trying to establish is, for the FIRST period of time the accout paid for this service, for how many consecutive months did they pay? Here is my test data:
if object_id('tempdb..#SampleData') is not null
drop table #SampleData
go
if object_id('tempdb..#DateAnalysis') is not null
drop table #DateAnalysis
go
-- Create temp tables for sample data

(3, '2/1/13'), (3, '3/1/13'), (3, '4/1/13'), (3, '9/1/13'), (3, '10/1/13'), (3, '11/1/13')
-- Use lead function to determine how many months are between
-- consecutive dates per account
; with DateInterval as
(select AccountID, RandomDate,
NextDate = lead (RandomDate, 1, NULL) over (partition by AccountID order by RandomDate)
from #SampleData)
insert into #DateAnalysis
select AccountID, RandomDate, NextDate,
datediff(mm, RandomDate, NextDate) as 'Lead'
from DateInterval
where NextDate is not null -- Last row will contain NULL for NextDate. Don't include these rows.
-- Show the results

'NTile' = NTILE(3) over (partition by AccountID order by RandomDate),

The problem comes with accounts like AccountID = 1. They paid consecutively to start, then skipped, then started paying consecutively again. When using window functions, I'm running into trouble attempting to partition by AccountID and LeadInMonths. It's putting all the LeadInMonths = 1 together and that will give me skewed results if I want to know the earliest and latest date within the FIRST consecutive range of dates where the account paid. I've tried NTILE but it expects an integer and there's no telling how many "tiles" would be in AccountID partition.
I've looked at the OVER clause and the new "ROWS BETWEEN" syntax and still cannot get the desired results.
I have 12 month report and I need show volume and difference between current and prev month volume, what is the smart way to do this, do I need to put prev month value onto same row horizontally? I think should be some other smart way, I heard about LEAD function?
This what I think for now, It should be listed per ClientID also, in my example I have single ClientID for simplicity.
I tried to do LEAD but with not success..
/*
IF OBJECT_ID('tempdb..#t') is not null drop table #T;
WITH R(N) AS
(SELECT 1 UNION ALL SELECT N+1 FROM R WHERE N <= 12 )
SELECT N as Rn,
10001 ClientID,
DATENAME(MONTH,DATEADD(MONTH,-N,GETDATE())) AS [Month],

please explain the differences btween this logical & phisicall operations that we can see therir graphical icons in execution plan tab in Management Studio
thank you in advance
I am using Full Text Index to index emails stored in BLOB column in a table. Index process parses stored emails, and, if there is one or more files attached to the email these documents get indexed too. In result when I'm querying the full text index for a word or phrase I am getting reference to the email containing the word of phrase if interest if the word was used in the email body OR if it was used in any document attached to the email.
How to distinguish in a Full Text query that the result came from an embedded document rather than from "main" document? Or if that's not possible how to disable indexing of embedded documents?
My goal is either to give a user an option if he or she wants to search emails (email bodies only) OR emails AND documents attached to them, or at least clearly indicate in the returned result the real source where the word or phrase has been found.
Dear All.
We had Teradata 4700 SMP. We have moved data from TD to MS_SQL SERVER 2003. records are 19.65 Millions.
table is >> Order_Dtl
Columns are:-
Client_ID varchar 10
Order_ID varchar 50
Order_Sub_ID decimal
.....
...
..
.
Pk is (ClientID+OrderId+OrderSubID)
Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.
The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.
Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)
My Question are:-
Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?
Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?
Q3. I want to check what indexes has been used? on what search?
Q4. How can i check what table was populated when, or last date of update (DML)?
My Limitation is i Dont Create a Partioned table. I dont have permission to do it.
In Teradata we had more than 4 tb record of CRM data with no issue. i am not new baby in db line but not expert in sql server 2003.
I am thank u to all who read or reply.

Hi,
I'm running a merge replication on a sql2k machine to 6 sql2k subscribers.
Since a few day's only one of the merge agents fail's with the following error:
The merge process could not retrieve generation information at the 'Subscriber'.
The index entry for row ID was not found in index ID 3, of table 357576312, in database 'PBB006'.
All DBCC CHECKDB command's return 0 errors :confused:
I'm not sure if the table that's referred to in the message is on the distribution side or the subscribers side? A select * from sysobjects where id=357576312 gives different results on both sides . .
Any ideas as to what is causing this error?
Hi everyone,
When we create a clustered index firstly, and then is it advantageous to create another index which is nonclustered ??
In my opinion, yes it is. Because, since we use clustered index first, our rows are sorted and so while using nonclustered index on this data file, finding adress of the record on this sorted data is really easier than finding adress of the record on unsorted data, is not it ??
Thanks
I have a clustered index that consists of 3 int columns in this order: DateKey, LocationKey, ItemKey (there are many other columns in this data warehouse table such as quantities, prices, etc.).
Now I want to add a non-clustered index on just one of the other columns, say LocationKey, like this:
CREATE INDEX IX_test on TableName (LocationKey)
I understand that the clustered index keys will also be added as key columns to any NC indexes. So, in this case the NC index will also get the other two columns from the clustered index added as key columns. But, in what order will they be added?
Will the resulting index keys on this new NC index effectively be:
LocationKey, DateKey, ItemKey
OR
LocationKey, ItemKey, DateKey
Do the clustering keys get added to a NC index in the same order as they are defined in the clustered index?
Quick question about the primary purpose of Full Text Index vs. Clustered Index.
The Full Text Index has the purpose of being accessible outside of the database so users can query the tables and columns it needs while being linked to other databases and tables within the SQL Server instance.
Is the Full Text Index similar to the global variable in programming where the scope lies outside of the tables and database itself?
I understand the clustered index is created for each table and most likely accessed within the user schema who have access to the database.
Is this correct?
I am kind of confused on why you would use full text index as opposed to clustered index.
Thank you

Hi All,
I 'm working to improve some sql performance.
One of the major syntax inside the SELECT statment is ..
WHERE FIELDA IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='A') AND
WHERE FIELDB IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='B') AND
WHERE FIELDC IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='C') AND
WHERE FIELDD IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='D') AND
WHERE FIELDE IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='E') AND
WHERE FIELDF IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='F')
(It's to compare the field content with some user input parameter inside a parameter table... )
I think properly is that the SELECT ... IN is causing much slowness in the sql statement. I have indexed FIELDA , FIELDB, FILEDC etc and those PARAVALUE and PARATYPE in the PARATABLE table. But perfromance is still slow and execution takes >20 seconds for 200000 rows of records.
Do any one know if still any chance to improvide the performance like this?
Much Thanks,
Andy
I'm trying to find whether there is a dmv or system view that can help me see the last time an index was rebuilt or created. Assuming I rebuilt an index using tsql commands (not a job with a history), is there a way to find out the last time that index was rebuilt?
Thanks much.
I have a really strange problem.
I execute this query:
declare @cid int
set @cid = 2003227
select * from sales s, product p where p.product_Id = s.product_Id and customer_id = @cid
select * from sales s, product p where p.product_Id = s.product_Id and customer_id = @cid or @cid = 0
3 Million rows in sales, 120000 in product.
The first does and index seek, the second an index scan.
The execution plan reports that the scan takes 99.87% of the cost, and the seek takes 0.13%
This problem obviously gets worse the bigger the dataset / query /etc.
The reason I query this, is because it never used to take this long to do index scans. Is there something i can change, something i can fix?
Any help would be appreciated.

Hello I want to learn disparity clustered index or nonclustered index and in queries which one run better.
example
select * from orders where orderID=5
to this query clustered or nonclustered
thanks
the query:
SELECT a.AssetGuid, a.Name, a.LocationGuid
FROM Asset a WHERE a.AssociationGuid IN (
SELECT ada.DataAssociationGuid FROM AssociationDataAssociation ada
WHERE ada.AssociationGuid = '568B40AD-5133-4237-9F3C-F8EA9D472662')
takes 30-60 seconds to run on my machine, due to a clustered index scan on our an index on asset [about half a million rows]. For this particular association less than 50 rows are returned.
expanding the inner select into a list of guids the query runs instantly:
SELECT a.AssetGuid, a.Name, a.LocationGuid
FROM Asset a WHERE a.AssociationGuid IN (
'0F9C1654-9FAC-45FC-9997-5EBDAD21A4B4',
'52C616C0-C4C5-45F4-B691-7FA83462CA34',
'C95A6669-D6D1-460A-BC2F-C0F6756A234D')
It runs instantly because of doing a clustered index seek [on the same index as the previous query] instead of a scan. The index in question IX_Asset_AssociationGuid is a nonclustered index on Asset.AssociationGuid.
The tables involved:
Asset, represents an asset. Primary key is AssetGuid, there is an index/FK on Asset.AssociationGuid. The asset table has 28 columns or so...
Association, kind of like a place, associations exist in a tree where one association can contain any number of child associations. Each association has a ParentAssociationGuid pointing to its parent. Only leaf associations contain assets.
AssociationDataAssociation, a table consisting of two columns, AssociationGuid, DataAssociationGuid. This is a table used to quickly find leaf associations [DataAssociationGuid] beneath a particular association [AssociationGuid]. In the above case the inner select () returns 3 rows.
I'd include .sqlplan files or screenshots, but I don't see a way to attach them.
I understand I can specify to use the index manually [and this also runs instantly], but for such a simple query it is peculiar it is necesscary. This is the query with the index specified manually:
SELECT a.AssetGuid, a.Name, a.LocationGuid
FROM Asset a WITH (INDEX (IX_Asset_AssociationGuid)) WHERE
a.AssociationGuid IN (
SELECT ada.DataAssociationGuid FROM AssociationDataAssociation ada
WHERE ada.AssociationGuid = '568B40AD-5133-4237-9F3C-F8EA9D472662')
To repeat/clarify my question, why might this not be doing a clustered index seek with the first query?

How do i perform this with the odbc configuration for oracle..and use the same in the dts.
