Recently we are having issues with one of the indexes during our maintenance. There is one index that which usually would have taken 10-15 mins continues to run even after 3 hrs. Other indexes on the same table finish nicely. Just this one gets stuck. Our index creation scripts drops existing index and creates new one..
CREATE INDEX ... ON ... WITH DROP_EXISTING, SORT_IN_TEMPDB ...etc
So last week when I got woken up because of this, I tried to drop the index explicitly and re create the index (by removing the DROP_EXISTING in above script). Even though it took about 45 mins it still finished in time during the maintenance window.
We had the same issue this week. I was looking at sp_who2 during the index creation, I noticed very low CPU activity and high DiskIO.
example: CPU : 4k cycles, DiskIO 50000.
There is 20% of free space on the index file group. Generally index creation takes higher CPU and lower DiskIO.
How do I find out what the issue is with this index? The table has 40 million rows. this is a non-clustered index. There are 2 other indexes on the table - one clustered. they both finished properly in less than 10 mins.
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.
Can I dynamically (from a stored procedure) generatea create table script of all tables in a given database (with defaults etc)a create view script of all viewsa create function script of all functionsa create index script of all indexes.(The result will be 4 scripts)Arno de Jong,The Netherlands.
Hi Minor and inconsequential but sometimes you just gotta know: Is it possible to define a non-primary key index within a Create Table statement? I can create a constraint and a PK. I can create the table and then add the index. I just wondered if you can do it in one statement. e.g. I have: CREATE TABLE MyT (MyT_ID INT Identity(1, 1) CONSTRAINT MyT_PK PRIMARY KEY Clustered, MyT_Desc Char(40) NOT NULL CONSTRAINT MyT_idx1 UNIQUE NONCLUSTERED ON [DEFAULT])which creates a table with a PK and unique constraint. I would like (pseudo SQL):CREATE TABLE MyT (MyT_ID INT Identity(1, 1) CONSTRAINT MyT_PK PRIMARY KEY Clustered, MyT_Desc Char(40) NOT NULL CONSTRAINT MyT_idx1 UNIQUE INDEX NONCLUSTERED ON [DEFAULT]) No big deal - just curious :D Once I know I can stop scouring BOL for clues. Tks in advance

I am trying to create an index on a view that joins two tables.
I get the classic error of course: 'Cannot index the view 'dbname.dbo.HJC_net'. It contains one or more disallowed constructs.'
Thing that gets me is that it all seems pretty normal stuff and I can't see what is stopping it.
Code is below and any help greatly appreciated.
CREATE VIEW dbo.HJC_net WITH SCHEMABINDING AS SELECTt_number FROM dbo.ticket_cancellations RIGHT OUTER JOIN dbo.tickets ON dbo.ticket_cancellations.tc_system_ref = dbo.tickets.t_number WHERE dbo.tickets.t_cancelled <> - 1 OR -- Add all cancellation codes that are to be excluded from the NET view below (dbo.ticket_cancellations.tc_cancellation_code <> 83943 AND dbo.ticket_cancellations.tc_cancellation_code <> 83946)

I was asked to import some data from excel into a table within a sqlserver 2000 db the import was complaining about an index so then I deleted the index imported the data succesfilly but I'm now unable to re create the index, please see the error that I'm getting below. Can someone please help. Thanks
- Unable to create index 'trainingGo'. ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 32. Most significant primary key is '439'. [Microsoft][ODBC SQL Server Driver][SQL Server]The statement has been terminated.
Are Primary Key fields automatically indexed, or do you have to create a seperate index for a PK in order for it to be indexed? I'm using SQL Server 2005.
Hi, all, I want to re-create an index on a production table. I got an error 644 "could not find index entry...". The DBCC CHECKDB and CHECKTABLE gave me this:
Server: Msg 8928, Level 16, State 1, Line 1 Object ID 37575172, index ID 6: Page (1:939782) could not be processed. See other errors for details. Server: Msg 8939, Level 16, State 1, Line 1 Table error: Object ID 37575172, index ID 6, page (1:939782). Test (*(((int*) &m_reservedB) + i) == 0) failed. Values are 7 and 36. DBCC results for 'Mfg_DFSFNSF'. There are 1142314 rows in 326143 pages for object 'Mfg_DFSFNSF'. CHECKTABLE found 0 allocation errors and 2 consistency errors in table 'Mfg_DFSFNSF' (object ID 37575172).
The table script for the index is like this:
CREATE UNIQUE INDEX [Mfg_ITMDH_MbrIdx] ON [dbo].[Mfg_DFSFNSF]([_ITMDH_OwnRow], [_ITMDH_MbrKey], [RECTYPE]) WITH FILLFACTOR = 70 ON [PRIMARY]
My question is that can I drop it and run above create it to fix the problem in live mode?
I know the other option will be: DBCC CHECKTABLE (FSDBMR.dbo.Mfg_DFSFNSF, repair_allow_data_loss) But that has to put the db under single user mode.
Hi guys. I have a table named [Check] and need to create an index for CVNumber field. The table has no primary key for the meantime. I tried this script but error occured.
BEGIN TRANSACTION SET QUOTED_IDENTIFIER ON GO SET TRANSACTION ISOLATION LEVEL SERIALIZABLE GO COMMIT BEGIN TRANSACTION CREATE NONCLUSTERED INDEX IX_Check_1 ON dbo.[Check] ( CVNumber ) ON [PRIMARY] GO COMMIT
Error message:
Server: Msg 3023, Level 16, State 2, Line 3 Backup, CHECKALLOC, bulk copy, SELECT INTO, and file manipulation (such as CREATE FILE) operations on a database must be serialized. Reissue the statement after the current backup, CHECKALLOC, or file manipulation operation is completed. Server: Msg 3902, Level 16, State 1, Line 1 The COMMIT TRANSACTION request has no corresponding BEGIN TRANSACTION.
Is it because I used the table name Check which is a reserved word for SQL? But I included [ ].
I have a view on the table. The Output of the view is PID, Postcode, ADDRESS (which is Address1 - Address5 concatenated into one string with spaces between notnull values)
I use a sproc to search the view for an address based on a free-text search. Sproc as below. Can anyone advise how I should index the table? I have never created an index before and need to speed up the search, which at the moment is simply to slow. I have 1.8 million records in the table.
Here is the sproc:
SELECT PID, Upper(Postcode) as 'Postcode', ADDRESS FROM vw_Postcode
WHERE Address Like '%' + REPLACE(REPLACE(@address,',','%'),' ','%') + '%' OR Postcode Like '%' + REPLACE(REPLACE(@address,',','%'),' ','%')+ '%'
I have SQL Server 2005 x64. I found in the studio I can generate allsorts of scripts, including the creation of indexes.I works, however the script contains the CREATE TABLE statements aswell. I want the scripts to recreate the scripts on another filegroup(testing a theory from previous post).Am I missing a switch in the wizard to exclude CREATE TABLE?I did create the script, but then I manually deleted all the CREATETABLE statements, which was a pain.ThanksRob

I have a table there is a query which has bad performance. This query normally can not use index because a lot of 'IS NULL','OR','LIKE' USED in where clause. I want to create a covering index for this query so it can use index scan only rather than Processor had to look up the row columns it needs from a table or a clustered index.
current there are two index apply on that table:

I have created the companyid as Primary Key.How to create a unique secondary index on Company Name. To avoid inserting duplicate records in database with the same companyname. I m creatin database in sql server 2005 with asp.net C# 2005. I know one way is write the query if not exists at the time of insert.But,i want to know is there anyother way to make a unique secondary index for the companyname on the company tablethanxs
Hello all,I'm wanting to do a CONTAINS query on fields that belong to two seperate tables. So, for example, this is what I'd *like* to do :SELECT ci.itemNameFROM Content_Items ciINNER JOIN Content_Pages AS cp ON ci.contentItemId = cp.contentItemIdINNER JOIN FREETEXTTABLE(Content_Items, (ci.title, cp.pageText), @searchString) AS ft ON ci.contentItemId = ft.[KEY]However, this will not work, since SQL Server won't let you do fulltext queries against more then one table.So my idea is to create a view that combines my Content_Items table with the desired column from my Content_Pages table. I would then create a fulltext index on this view, and do fulltext queries against it.It seems like this should work. However, when I try to create a fulltext index on my newly-created view, I get this error :A unique column must be defined on this table/view.How do I create a unique column within a view?Also, will my approach work, or will it have unintended consequences? I'm using this as part of a search component in my software, so it has to perform reasonably well.
