I am creating an index on a table wit 35 million records but I get the error
'TT_ObjPerformance' table
- Unable to create index 'IX_TT_ObjPerformance_CACode'.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
How can I get the index created?

Hi,
Trying to optimize a query but not sure what to do. I have this query on which I ran an exec plan,
SET NOCOUNT ON;
SELECT qaTestSuite.TestSuiteID, qaTestSuite.TestSuiteStart, qaTestSuite.TestInterface, qaTestSuite.TestVersion, qaTests.TestMachine, qaTestSuite.TestClientMachine, qaTests.TestLogin, qaTests.TestLabel,
qaTestSuite.TestCLPs, qaTestSuite.TestSuiteEnd, qaTests.TestID, qaTests.TestIDInternal, qaTests.TestStart,
qaTests.TestName, qaTests.TestTier, qaTests.TestNo, qaTests.TestWFBCalled, qaTests.TestWFBTime,
qaTests.TestSearches, qaTests.TestSearchesTime, qaTests.TestResult, qaTests.TestEnd, qaTestMssgs.TestMssgsID,
qaTestMssgs.TestMssgTime, qaTestMssgs.TestMssgType, qaTestMssgs.TestMessage, qaTestSuite.TestMode
FROM qaTestSuite with(NOLOCK) INNER JOIN
qaTests with(NOLOCK) ON qaTestSuite.TestSuiteID = qaTests.TestSuiteID INNER JOIN
qaTestMssgs with(NOLOCK) ON qaTests.TestID = qaTestMssgs.TestID
order by qaTestSuite.TestSuiteStart DESC
and it gives me the following results:
Use a Bookmark (RID or Clustering Key) to look up the corresponding row in the Table or Clustered Index.

I have no idea what to do with that. Anyone have any clues? What I found online was that I should make a Covering Index, but I didn't find
any patterns on how to do that. Any one have ideas of how to do this?
Thanks very much for your help!

Hi
i am new to using this sql server 2000....this is a very simple question to all u guys.....i am just in a learning stage...so any help from u guys is really appreciable....
i need to create a table customers with the following columns...
identity column to self-populate as the primary key,
joindate, leavedate, custcode, empID.
This is the one i tried:
create table customers (id int primary key identity (1,1) not null,
joindate smalldatetime null,
leavedate smalldatetime null,
custcode varchar (10) not null,
empid int not null
)
is tht code correct only???
and i also want the below one :
Create indexes on the leavedate, custcode and empid columns.
how to create these indexes???
and wht happens when i create them(like is thr any advantage of creating indexes???)
thanks......
HiI tried the following from the help file...When you create or modify a unique index, you can set an option toignore duplicate keys. If this option is set and you attempt to createduplicate keys by adding or updating data that affects multiple rows(with the INSERT or UPDATE statement), the row that causes theduplicates is not added or, in the case of an update, discarded.For example, if you try to update "Smith" to "Jones" in a table where"Jones" already exists, you end up with one "Jones" and no "Smith" inthe resulting table. The original "Smith" row is lost because anUPDATE statement is actually a DELETE followed by an INSERT. "Smith"was deleted and the attempt to insert an additional "Jones" failed.The whole transaction cannot be rolled back because the purpose ofthis option is to allow a transaction in spite of the presence ofduplicates.But when I did it the original "Smith" row was not lost.I am doing something wrong or is the help file incorrect.Dan

but when I generate the SQL script for that table its not
creating the primary key

Does anyone have a general rule or guide on when to use this SQL 2000 option when creating indexes? I was thinking generally on nonclustered indexes where the column would be unique and incremental and usually filtered on by range and often used in the order by clause. Such as columns of datetime or integers datatypes. Thanks.
View 1 Replies View Relatedhave a 3rd party app (can't change) which has some bad sql. I have a table that is used in the sql which if I put a clustered (I had an index on the fields in the sql but it would ignore and table scan) will use and stop doing table scan. this is a million row table that is growing. the data going in is pretty mich insert only. I have a separate array and file group which I have moved indexes to last year. 2 questions
1. If I would make a clustered index on the separate RAID and file group, doesn't the table need to go with it. I thought the clustered index and table had to be on same File Group
2. If I do this anyone see any issues with moving this table and index on this file group
Hi Guys,
I have a SQL 2000 sp3a server on Windows 2000 sp4. Running dual proc server with hyper threading enabled, 3gb memory attached to a HP EVA 5000 SAN.
One of the tables is 67gb and contains 140,000,000 rows. Recently someone dropped the clustered indexe so i`m trying to put it back (i've dropped the non clustered indexes as no point leaving them there whilst clustered builds).
The problem i am having is the rebuild is taking forever!! It ran for 23 hours before someone rebooted the server (!). The database is currently recovering from the reboot but i need to work out what is causing the appalling performance so i can get the index rebuilt. There are no reported hardware problems.....
There are multiple file groups involved and i found i was getting an extent allocation rate of 1.5 extents a second and same for deallocation.
Any advice on how to trouble shoot this?
Hi,
I have created a very simple table. Here is the script:
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[IndexTable]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[IndexTable]
GO
CREATE TABLE [dbo].[IndexTable] (
[Id] [int] NOT NULL ,
[Code] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL
) ON [PRIMARY]
GO
CREATE CLUSTERED INDEX [CusteredOnCode] ON [dbo].[IndexTable]([Id]) ON [PRIMARY]
GO
ALTER TABLE [dbo].[IndexTable] ADD
CONSTRAINT [PrimaryKeyOnId] PRIMARY KEY NONCLUSTERED
(
[Id]
) ON [PRIMARY]
GO
The records that i added are:
Id Code
1 a
2 b
3 aa
4 bb
Now when i query like
Select * from IndexTable
I expect the results as:
Id Code
1 a
3 aa
2 b
4 bb
as i have the clustered index on column Code.
But i m getting the results as:
Id Code
1 a
2 b
3 aa
4 bb
as per the primary key order that is a non clustered index.
Can anyone explain why it is happening?
Thanks

I have a table called as A table :
CREATE TABLE [dbo].[A](
[AutoID] [int] IDENTITY(1,1) NOT NULL,
[ProID] [int] NOT NULL,
[LID] [varchar](12) NOT NULL,
[EventID] [varchar](12) NOT NULL,
[HEventID] [varchar](12) NULL,
) ON [PRIMARY]
How I should creating the appropiate index for this table?A few option that I think ok.
Opt 1 : creating a primary key on the autoID with create index . create non clustered index on ProID and EventID
Opt 2 : create a primary key on the autoID with non clustered index . create clustred index on ProID and EventID .
opt 3: create primary key on the ProID and EventID with clustered index.
I have read thru the article on the primary key, clustered and non clustered indexing. However when I want to applyied the indexing..I feel a bit lost.But among the 3 option.... what is the different..
Hi, Folks!
I'm receiving Access Violation Error when I'm trying to create a clustered index on a datetime field on a table that have around 4 million records, if I create the index nonclustered, no problem, but clustered the system raise this error!
Any help will be appreciate a lot!
Thanks in advance!

In a Stored Proc I am creating the following temp table and index:
CREATE TABLE [dbo].[#ShipTo](
[Ship_to_Num] [int] NOT NULL,
[Country_key] [nvarchar](3) NULL,
CONSTRAINT [PK_ShipTo] PRIMARY KEY CLUSTERED
(
[ship_to_Num] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
The stored Proc runs fine from "exec", but when you batch into a Job it gives the error that "PK_ShipTo" already exists! I even put in a drop table on #ShipTo, but the same effect.
I have 5 million rows of table, and going to create Non Clustered Index for Datetime values column. Creating Non clustered Index on Datetime value column will affect performance or not.

Anyone know the syntax and function to create a self incrementing index whilst extracting data? I'm using the Derived Column tool. The extract will be a full extract everytime, not incremental.
Thanks.
Hi all,
Im new to sql and very interreseted in the Full text features, however when im trying to execute the following query:
USE Updater
CREATE FULLTEXT INDEX ON dbo.Servers (ServerName)
KEY INDEX ServerID
ON UpdaterCatalog
WITH CHANGE_TRACKING AUTO
GO
Where ServerID = Int NOT NULL IDENTITY and ServerName = VarChar(255) NOT NULL and UpdaterCatalog is just created
I get the following error:
Msg 7653, Level 16, State 1, Line 3
'ServerID' is not a valid index to enforce a full-text search key. A full-text search key must be a unique, non-nullable, single-column index which is not offline, is not defined on a non-deterministic or imprecise nonpersisted computed column, and has maximum size of 900 bytes. Choose another index for the full-text key.
I cant seem to figure out why this wont work since unless im mistaking, both fields are legal.
Note that creating an index on any other table doesn't work either.
Im running Sql server standard edition (32 bits) on VISTA Ultimate X64
Thanks in advance,

Hi,
i have created index for a temporary table and this script should used by multiusers.So when second user connecting to it is giving index i mean object already exists.
So what i need is when the second user connected the script should create one more index on temporary table.Will sql server provide any random way of creating indexes if the index exists already with that name??
Thank You,
Does including non-key columns work for the performance of an index?
View 8 Replies View RelatedI used following query to identify missing indexes:

I think I need to only create few if an index is covering all columns then I do not need to create more indexes for separate columns or should I create separate index as suggested?

Hi,
I've created initial indexes for my table for the fuzzylookup process. I clicked on "Maintained index" but I don't see any triggers created on the reference table.
Do I create the triggers to maintain indexes myself?
Does anybody know how to create these triggers in terms of schema_name, Data_Modification_Statements etc.?
Would it be "Alter index <index name> REBUILD command?
Appreciate the help.

Hello!
I have a problem. I want to know if the time which is needed for creating an index increases proportional to the amount of rows. example: if creating an index on a table which 10.000 rows takes 15 seconds. does creating an index on a table with 20.000 rows take 30 seconds , 40.000 rows 60 seconds and so on...
or does it take longer like 10.000 rows 15 second, 20.000 rows 40 seconds, 40.000 rows 80 seconds.
thx for your help!!

I hope i'm in the right place, but thanks anyway....
Actually i have 2 questions (regarding sql-server Indices/Keys):
1) I have an index, which is consisted of 4 columns.
I've read elsewhere that this index functions (as well) as an index (single column
index) on the first column of this multi-column index.
Does this mean that if i'd like to have (in addition) Indices on all of the 4 columns
seperately i need to define only 3???
2) I have a unique key consisted of multiple columns.
I'd like to save an index to this combination of columns as well (to speed up
things in DB...).
Does the definition of a multiple-columns key free me from defining the multiple-
columns index???
can anyone explain the main diference between Keys and Indices???

Hello..
When I used Microsoft SQL Server 2005 Management Studio Express to Create FULL TEXT INDEX by this code:
CREATE FULLTEXT INDEX ON txtfilestbl(txtfile) KEY INDEX PK_txtfilestbl ON ForumsArchiveLibCtlg WITH CHANGE_TRACKING AUTO
It returns this ERR MSG:
Informational: No full-text supported languages found.
Informational: No full-text supported languages found.

Default full-text index language is not a language supported by full-text search.
I Use same this code to create FULL TEXT INDEX by using Microsoft SQL Server 2005 Management Studio, and it was working properly.

I am trying to create a clustered index on a View of a table that has an xml datatype. This indexing ran for two days and still did not complete. I tried to leave it running while continuing to use the database, but the SELECT statements where executing too slowly and the DML statements where Timing out. I there a way to control the server/cpu resources used by an indexing process. How can I determine the completion percentage or the indexing process. How can I make indexing the view with the xml data type take less time?

I am looking to create a constraint on a table that allows multiplenulls but all non-nulls must be unique.I found the following scripthttp://www.windowsitpro.com/Files/0.../Listing_01.txtthat works fine, but the following lineCREATE UNIQUE CLUSTERED INDEX idx1 ON v_multinulls(a)appears to use indexed views. I have run this on a version of SQLStandard edition and this line works fine. I was of the understandingthat you could only create indexed views on SQL Enterprise Edition?

I have a query which executes in 1 second and returning 14 rows whenever I execute it through Management Studio but when I execute it from a web page I am getting a timeout message and the stack trace is pointing towards the line which calls the stored procedure. The query is quite complex and there quite a few joins on tables and views including one to a lookup table, whenever I take out join onto the look up table the web page runs ok without timing out. I join the Lookup table (Parts) using a Left Outer Join similar to below. The syntax of the Join is fine but I cant find why it would cause the query to time out when executed from a webpage but is fine when I execute it from Management Studio
select *
from tables/view LEFT OUTER JOIN
Parts on Parts.PartNumber=tables/View.PartNumber
I've tried recompiling the Parts table but it didnt make any difference.
Any help would be much appreciated.

I use SQL Server to provide data to asp web pages and have recently started to get ODBC time outs throughout the day.
The environment is as follows:
Server with dual PII processors & 512MB RAM running:
- SQL Server 7
- IIS
I have a number of asp based web sites hosted on this box, but only 1 of them seems to be affected by the time out problem. I have checked the resources on the server (NT Task Mgr - Memoey & Processor) and everything seems fine - in fact the resources are hardly being touched!!!
Within a few minutes the problem disappears completely without me doing anything.
Am I missing something here?
Should I look elsewhere other than SQL - maybe IIS ???
Any suggestions / pointers would be very much appreciated.
Thx
We are using asp's and tables sucessfully but when we click a link to an exe on a page it is slow, to the point of timing out. Very slow. Any help would be appreciated. Email me tperry@kpmg.com
