Hi All,
is it really improve performance that making table reindexing?
what i mean to say is i've one script, which will automatically drops all the indexes in a database, and reconstruct them with the same name.
is it really worth doing that?.....
thankyou very much

Attempt to fetch logical page (1:166354) in database 'pm_pmc_prod' belongs to object '837120', not to object 'ng_visit'.
I got his error while importing data into the error, when i ran dbcc checkdb it gave me Msg 8928,8942,8976 etct witl serverity level 16...
is it possible to fix this curropt tables?
We load tables from text files for inquiries.
My procedure is to truncate the table
Use DTS to move the text file into the table
do the command DBCC DBREINDEX (TABLE,'')
Am I wasting my time?
Does SQL 7 rebuild the indicis as it loads the data from the text file?
Hello guys,
Two things:
1) Could somebody explain me how to reindex all tables in my db?
2) How do I know when I should reindex my db?
Thank you very much for any help!

my favorit hoster is ASPnix : www.aspnix.com !
I've just recently tried to perform a scheduled reindexing job with the following command:
EXEC sp_MSforeachtable @command1="print '?' DBCC DBREINDEX ('?')"
Unfortunately, this command has only finished once of the five or six times I've tried to run it. The times it has failed, it deadlocks behind what seems to be a succession of other transactions. How can I make sure this command finishes?
Hello Everyone,
I need to rebuild all indexes in one table, is there any command that will do automatically instead of deleting and recreating them all?
Any help will be appreciated.
Thanks
All,
I've got a medium sized database in a mirror configuration with witness. The database size is about 300gb and I would to reindex all of the tables in the database. My process would go something like this:
1) Backup principal
2) Break the mirror
3) Set the principal database to simple recovery mode
4) Perform the reindexing
5) Backup the principal and transfer that backup to the mirror
6) Restore the backup
7) Re-establish the mirror
Does anyone see any issues with the process itself?

Hi experts,
For defragmenation and reindexing they are using the below cursor, and now they have asked me to remove the cursor and schedule the job accordingly to do the same functionality, so what will be the other way we can do without cursor? can you plase let me know the solution?
DECLARE @Database VARCHAR(255)
DECLARE @Table VARCHAR(255)
DECLARE @cmd NVARCHAR(500)
DECLARE @fillfactor INT
SET @fillfactor = 90
DECLARE DatabaseCursor CURSOR FOR
SELECT database_name FROM dbadmin.dbo.tdbstatus WHERE status='y'
AND database_name NOT IN ('master','model','msdb','tempdb')
ORDER BY 1
OPEN DatabaseCursor
FETCH NEXT FROM DatabaseCursor INTO @Database
WHILE @@FETCH_STATUS = 0
BEGIN
SET @cmd = 'DECLARE TableCursor CURSOR FOR SELECT table_catalog + ''.'' + table_schema + ''.'' + table_name as tableName
FROM ' + @Database + '.INFORMATION_SCHEMA.TABLES WHERE table_type = ''BASE TABLE'''
-- create table cursor
EXEC (@cmd)
OPEN TableCursor
FETCH NEXT FROM TableCursor INTO @Table
WHILE @@FETCH_STATUS = 0
BEGIN
SET @cmd = 'ALTER INDEX ALL ON ' + @Table + ' REBUILD WITH (FILLFACTOR = ' + CONVERT(VARCHAR(3),@fillfactor) + ')'
EXEC (@cmd)
FETCH NEXT FROM TableCursor INTO @Table
END
CLOSE TableCursor
DEALLOCATE TableCursor
FETCH NEXT FROM DatabaseCursor INTO @Database
END
CLOSE DatabaseCursor
DEALLOCATE DatabaseCursor
Your help will be appreciated.
In the Enterprise Manager of SQL Server 2000 I have set up a maintenance plan which rebuilds my indexes. I've stuided the documentation, and from what I've learned what happens behind the curtain is that several DBCC REINDEX commands are being issued.
Question:
If I have 20 tables and 40 indexes: Will SQL Server do the maintance plan in 1 single transaction, or will it divide the it up to eg. 20 or 40 transactions?

Hi
We are upgrading from sql 7 to 2000.During the upgrade process do we have to do a reindexing of all tables or will update statistics take care of that.
Or do we have to do both?
What is the difference between reindexing and update statistics.
Thanks

Hi All,
Just after some feedback on a scenario where we have full logging setup on one of the databases, and the transaction logs are backed up every 60min. At 0000-0100 the log jumps from being a few thousand k up to over 1.7gb.
I did some profiling for this time, and it appears that this jump is related to the reindexing of the indexes on the database.
Is this normal for the log file to jump in size so much? Or is this an indication of some other issue (potentially with the indexes)?
Is there any way that the reindexing can be excluded from the log files or is this a necessity?
Thanks in advance for your help.
Cheers

hi
i have reindex of the tables
is it really improve performance that making table reindexing ?
Folks,I work on a system which is growing rapidly, with the number oftransactions we process growing on a daily basis. While this is goodnews or the business, maintenance is starting to become an issue as thedatabase is the backend for a website which cannot be down for alengthy period of time.While I do defrag the indexes, periodically the indexes do need to berebuilt. When this happens, the process locks pages and transactionsstart getting bounced out.Are their any third party utilities which will rebuild an indexwithout this locking occuring? Any help in pointing me in the rightdirection would be appreciated.
View 1 Replies View RelatedDoes someone know if doing a reindex on a clustered or non-clustered index cause the snapshot file to grow? In other words, is the data that makes up the snapshot copied from the source to the snapshot database? If a normal reindex is done on the underlying database, will it block users from acessing the snapshot? Any help would be appreciated.

Hi,
We have scheduled a job for DB Reindexing (Maitinance Plan) for a OLTP database on sunday.
We have used mirroring for automatic failover with a witness server now the DR Reindexing job fails after 30 mins without any error.
Please let me know why Database reindexing gets failed.

Hello,
I'm looking for the query command that will go out to all the user Tables and will tell me what Indexes need to be reindexed.
We are having a problem with some of the tables and we don't know when our tables need to be reindexed other than when operations are stopped for our company.
Thanks,
Ron
Hello. When reviewing the DBCC SHOWCONTIG immediately after reindexing all indexes on a database, I see the ExtentFragmentation has values like 50 to 70%... These are SQL 2005 tables with clustered PK's, no large varchars/blobs, and at least 100 pages in the index... The numbers related to PAGE fragmentation are ok after reindexing, but not the EXTENT fragmentation numbers.
I noticed the drive is in need of being defragged at the disk level. Is that a reason why reindexing doesn't fix the Extent frag numbers?? ANy other ideas on this? I can try defragging the DISK over the weekend, bringing the database offline then, but any other thougths on why the Extents show these high %'s? Is there any command to reset them and maybe that isn't happening? Like must I do update usage to get valid Extent frag #'s??
If there were MANY autogrows on the files, is that a different level of fragmentation? and how could all those small pieces of files be pulled back together? Thanks, Bruce
I am using SQL Server 2005 and trying to create a linked server on Oracle 10. I used the commands below:
EXEC sp_addlinkedserver
@server = 'test1',
@srvproduct = 'Oracle',
@provider = 'MSDAORA',
@datasrc = 'testsource'
exec sp_addlinkedsrvlogin
@rmtsrvname = 'test1',
@useself = 'false',
@rmtuser='sp',
@rmtpassword='sp'
When I execute
select * from test1...COUNTRY
I get the error. "The OLE DB provider "MSDAORA" for linked server "...." does not contain the table "COUNTRY". The table either does not exist or the current user does not have permissions on that table."
The 'sp' user I am connecting is the owner of the table. What could be the problem ?
Thanks a lot.
I have created a table Table with name as Varchar and id as int. Now i have started inserting the rows like, insert into Table values ('arun',20).Yes i have inserted a row in the table. Now i have got the values " arun's ", 50. insert into Table values('arun's',20) My sqlserver is giving me an error instead of inserting the row. How will you solve this problem?
Hi

the rows which are having currentstatus as "ticket closed",i want to move those rows into other table called repository which is having same table structure as status table.
I can do programatically.
but is there any way for every 3 months system has to check and do this action means moving to repository table automatically?
Please help me.
Thanks.
I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual
(empno,
accrued_vacation,
accrued_sick_effective_date,
accrued_sick,
import_date)
[Code] ....
For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.
View 6 Replies View RelatedHi all,
The following dbo.Tables of Northwind.mdf in my .SQLEXPRESS (SQL Server Management Studio Express) are missing:
dbo.Categories
dbo.CustomerCustomerDemo
dbo.CustomerDemographics
dbo.Customers
dbo.Employees
dbo.EmployeeTerritories
dbo.Order Details
dbo.Orders
dbo.Products
dbo.Regions
dbo.Shippers
dbo.Suppliers
dbo.Territories.
But, I have these dbo.Tables in a different Database "xyzDatabase". How can I copy each of these dbo.Tables to the another blank dbo.Table of Northwind Database?
I right clicked on the dbo.Categories and I saw the following thing:
dbo.Categories
New Table...
Modify
Open Table
Script Table as |> CREATYE To |>
DROP To |>
SELECT To |>
INSERT To |> New Query Editor Window
File....
Clipboard
UPDATE To |>
DELETE to |>
From the above observation,I think it is possible to copy the dbo.Table from the one Database to the Northwind Database that needs to be repaired. Please help and advise me how to do this task or tell me where I can find the Microsoft document that gives the details of this X-copy thing.
Thanks in advance,
Scott Chang
P. S. I am using VB 2005 Express to create a project to learn "Calling Stored Procedures with ADO.NET" (see Paul Kimmel's article in http://www.developer.com/db/article.php/3438221) that needs the dbo.Tables of Northwind Database and my Northwind Database has been screwed up for quite a while and needs a big repair.
which is more efficient...which takes less memory...how is the memory allocation done for both the types.

View 2 Replies View RelatedHi thanks for looking at my question
Using sqlServer management studio 2005
My Tables are something like this:
--Table 1 "Employee"
CREATE TABLE [MyCompany].[Employee](
[EmployeeGID] [int] IDENTITY(1,1) NOT NULL,
[BranchFID] [int] NOT NULL,
[FirstName] [varchar](50) NOT NULL,
[MiddleName] [varchar](50) NOT NULL,
[LastName] [varchar](50) NOT NULL,
CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED
(
[EmployeeGID]
)
GO
ALTER TABLE [MyCompany].[Employee]
WITH CHECK ADD CONSTRAINT [FK_Employee_BranchFID]
FOREIGN KEY([BranchFID])
REFERENCES [myCompany].[Branch] ([BranchGID])
GO
ALTER TABLE [MyCompany].[Employee] CHECK CONSTRAINT [FK_Employee_BranchFID]
-- Table 2 "Branch"
CREATE TABLE [Mycompany].[Branch](
[BranchGID] [int] IDENTITY(1,1) NOT NULL,
[BranchName] [varchar](50) NOT NULL,
[City] [varchar](50) NOT NULL,
[ManagerFID] [int] NOT NULL,
CONSTRAINT [PK_Branch] PRIMARY KEY CLUSTERED
(
[BranchGID]
)
GO
ALTER TABLE [MyCompany].[Branch]
WITH CHECK ADD CONSTRAINT [FK_Branch_ManagerFID]
FOREIGN KEY([ManagerFID])
REFERENCES [MyCompany].[Employee] ([EmployeeGID])
GO
ALTER TABLE [MyCompany].[Branch]
CHECK CONSTRAINT [FK_Branch_ManagerFID]
--Foreign IDs = FID
--generated IDs = GID
Then I try a simple single row DELETE
DELETE FROM MyCompany.Employee
WHERE EmployeeGID= 39
Well this might look like a very basic error:
I get this Error after trying to delete something from Table €œEmployee€?
The DELETE statement conflicted with the
REFERENCE constraint "FK_Branch_ManagerFID".
The conflict occurred in database "MyDatabase",
table "myCompany.Branch", column 'ManagerFID'.
Yes what I€™ve been doing is to deactivate the foreign key constraint, in both tables when performing these kinds of operations, same thing if I try to delete a €œBranch€? entry, basically each entry in €œbranch€? and €œEmployee€? is child of each other which makes things more complicated.
My question is, is there a simple way to overcome this obstacle without having to deactivate the foreign key constraints every time or a good way to prevent this from happening in the first place? Is this when I have to use €œON DELETE CASCADE€? or something?
Thanks
In a table-valued UDF, does the UDF use a table variable or a temp table to form the resultset returned?
Banti writes "IF i create temporary table by using #table and ##table then what is the difference. i found no difference.
pls reply.
first:
