Sep 26, 2007
Hi ,
I would like to create index for a table and that index name must be random generated.
How to do this?

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.

I created a cursor that moves through a table to retrieve a user's name.When I open this cursor, I create a variable to store the fetched name to use within the BEGIN/END statements to create a login, user, and role.
I'm getting an 'incorrect syntax' error at the variable. For example ..
CREATE LOGIN @NAME WITH PASSWORD 'password'
I've done a bit of research online and found that you cannot use variables to create logins and the like. One person suggested a stored procedure or dynamic SQL, whereas another pointed out that you shouldn't use a stored procedure and dynamic SQL is best.

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 creating a table variable (@tblBin) to temporarily store a set of data. Later in my sproc, I am doing a JOIN from @tblBin to a persistent table. In order to improve performance, I was thinking of adding an index to the columns of the @tblBin (indexes already exist on the persistent table). Using standard CREATE INDEX syntax(*), I am getting a compile error. Can this be done?
(*)CREATE NONCLUSTERED INDEX IX_tblBin_shortname ON @tblBin(shortname)
TIA ...

Hi,I've got 2 table variables inside of an SQL 2000 function:@tmpBigList(BItemID, BRank)@tmpSmallList (ItemID, Rank)The following UPDATE statement can run for a long time if @TmpTable1has 500 rows and @TmpTable2 has 35,000 rows.UDPATE @tmpBigListSET BRank = t.RankFROM @tmpBigListJOIN @tmpSmallList t on t.ItemID = BItemIDLooking at the Query Plan, you see that the INNER JOIN Of @tmpBigListto @TmpSmallList results in 500 * 35,000 = 17,500,000 rows beingreturned from @TmpSmallList. That takes a long time.An index would help, but it appears that you can't add an index to atable variable.Changing to a temp table does not work since it's in a function.Thanks,Joe Landes

Hi,Here's my problem: I want to write a stored procedure that returns allrecords from a table that have a certain column starting with giventext. I however find that using LIKE and a variable always causes anindex scan... which is causing performance issues. My table has about3.5M records.Below is a test. In query analyser if I look at the execution plan forthe following it will come up as in index scan. However, if i justhard-code the text it all works fine (index seek).How can I do this with reasonable speed???Thanks GregDECLARE @find varchar(50)SET @find = 'start'SELECT TOP 100*FROM TestWHERECol1 LIKE @find + '%'--Col1 LIKE 'start%'

Hi:
I am trying to loop through 4 files in a folder and read the names of those files through the For each loop container task. I have 4 readme files (readme1.txt thru readme4.txt) in a folder called C:SSIS.
I have added a for each Loop container and a script task to my package. In the Variable Mapping page I have named the Variable and configured the index to be 0. The problem is when I execute the package the file name that is read is always readme1.txt. I want all the file names to be read under the folder ( in other words configure the index to be 0 thru 4). How do I configure the index so that it can read all the files?.
The following is the code I have in my script task:
Public Sub Main()
Dim variables As Variables
If Dts.Variables.Contains("FileName") = True Then
Dts.VariableDispenser.LockOneforRead("FileName", variables)
End if
Msgbox ("Retrieved the File " & CStr(variables("FileName").Value))
Dts.TaskResult=Dts.Results.Success
End Sub
When I execute the package with the above code, I always see a message box popping up and saying Retrived File Readme1.txt.
I want the msgbox to pop up and say
Retrieved Readme1.txt
Retrieved Readme2.txt
Retrieved Readme3.txt and so forth...
Any help on achieving this is appreciated.
Thanks
AK

Hi all
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.
Thanks in advance,
Don

G'day all.
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)
GO
-- Create a clustered index, it MUST be unique
CREATE UNIQUE CLUSTERED INDEX t_number_unique ON HJC_net(t_number)

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.
Thanks!

Is it because I used the table name Check which is a reserved word for SQL? But I included [ ].

I am using SQL SERVER 2005 Express. I am trying to set up CREATE FULLTEXT INDEX.
I have confirmed that the Fulltext is installed with:

So no I need to create a Full Text index:
CREATE FULLTEXT INDEX

But I get this error:

I have a table as follows:
PID (PK), int
Postcode, nchar
Address1, nvarchar
Address2, nvarchar
Address3, nvarchar
Address4, nvarchar
Address5, nvarchar
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,',','%'),' ','%')+ '%'

Good day!
We had decided to migrate from Oracle to SQL Server, so faced some problems. Using Oracle we could create indexes like that
create index obj_id_cnum on obj_id (substr(cnum,1,2))
But Microsoft SQL Server doesn't allow this code. How can we do the same using SQL Server. Thanks you.

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:
CREATE UNIQUE CLUSTERED INDEX [Person_RecordID_UIX] ON Person
(
[RecordID] ASC
)
go
ALTER TABLE [Person] ADD CONSTRAINT Person_PK PRIMARY KEY NONCLUSTERED
(
[EntityID] ASC
)
How to add a covering index for the columns such as familyName,givenName, dob. All of these columns are not too much high selective.
Can I do like the following :
--create third index
CREATE NONCLUSTERED INDEX [Person_Cover_IX] ON [dbo].[Person]
(
[EntityID] ASC
)
INCLUDE ( [FamName],
[FirstName],
[DOB],
[Gender]
)
Or DROP Current index on entityid and recreate it with include clause.
What's the different between these two.
Thank you.

I'm about ready to smash my computer. I've installed SQL Server 2005 Express Edition with Advanced Services on Win XP Pro SP2. I made sure to enable the Fulltext service at install. Installed to the default instance name, and made sure the fulltext service is running from the CM. I made sure to enable full text indexing on my database from the properties window. I can create the fulltext catalog, but not the index!
----
create fulltext index on [person.contact] (Lastname)
key index [PK_Person.Contact] on myfulltextcatalog
Informational: No full-text supported languages found.
Informational: No full-text supported languages found.
Msg 7680, Level 16, State 1, Line 1
Default full-text index language is not a language supported by full-text search.
----------------------------------------------
select * from sys.fulltext_catalogs
returns the catalog
----------------------------------------------
sp_fulltext_service 'update_languages'
Informational: No full-text supported languages found.
----------------------------------------------
select @@language
us_english
----------------------------------------------
select * from sys.fulltext_languages
Returns an empty table
----------------------------------------------
SELECT * FROM sys.configurations
ORDER BY name ;
1126 default full-text language 1033 0 2147483647 1033 default full-text language 1 1
----------------------------------------------
Does anyone have any idea what's going on? I've already removed and re-installed a couple of times to different directories, used different instance names, and still no luck. Any help would be greatly appreciated.

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.
