Reindexing Tables
Sep 17, 2001I'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?

Reindexing Tables On A Databse That Is 36GB
Nov 3, 2005Hello,
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.

Reindexing A Database...
Oct 18, 2007
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?

REINDEXING IN VER 7
Jun 22, 1999We load tables from text files for inquiries.
My procedure is to truncate the table
Use DTS to move the text file into the table

Am I wasting my time?
Does SQL 7 rebuild the indicis as it loads the data from the text file?

Table Reindexing
Nov 15, 2007Hi 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

Refragmentation And Reindexing
Dec 27, 2007Hi 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.
Maintenance Plan, Reindexing
Mar 24, 2005In 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?

Reindexing Vs Update Statistics
Nov 22, 2004Hi
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

Reindexing And Transaction Logs
Dec 14, 2004Hi 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

Third Party Reindexing Utilities
Jul 23, 2005Folks,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 RelatedEffect On Snapshots While Reindexing
Apr 30, 2007Does 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.

Extent Fragmentation High Just After Reindexing
Jul 18, 2007Hello. 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

Can I Export Tables So That Existing Tables In Destination Database Will Be Modified?
Jul 20, 2005I'm working on an ASP.Net project where I want to test code on a localmachine using a local database as a back-end, and then export it tothe production machine where it uses the hosting provider's SQL Serverdatabase on the back-end. Is there a way to export tables from oneSQL Server database to another in such a way that if a table alreadyexists in the destination database, it will be updated to reflect thechanges to the local table, without existing data in the destinationtable being lost? e.g. suppose I change some tables in my localdatabase by adding new fields. Can I "export" these changes to thedestination database so that the new fields will be added to thedestination tables (and filled in with default values), without losingdata in the destination tables?If I run the DTS Import/Export Wizard that comes with SQL Server andchoose "Copy table(s) and view(s) from the source database" and choosethe tables I want to copy, there is apparently no option *not* to copythe data, and since I don't want to copy the data, that choice doesn'twork. If instead of "Copy table(s) and view(s) from the sourcedatabase", I choose "Copy objects and data between SQL Serverdatabases", then on the following options I can uncheck the "CopyData" box to prevent data being copied. But for the "CreateDestination Objects" choices, I have to uncheck "Drop destinationobjects first" since I don't want to lose the existing data. But whenI uncheck that and try to do the copy, I get collisions between theproperties of the local table and the existing destination table,e.g.:"Table 'wbuser' already has a primary key defined on it."Is there no way to do what I want using the DTS Import/Export Wizard?Can it be done some other way?-Bennett

Integration Services :: Import Varying Number Of Tables Each Time From One Database To Different Database
Sep 9, 2015I am new to SSIS. I have been struggling with this for the past one week. I have a weird task. I need to import several tables from one database to a different server with a new database name. We need to do this at the end of every year. The main problem here is that the number of tables varies every year. You may not have all the tables as last year or may have more tables. So I need to create a dynamic task that takes care of this every year without changing the package.
I have performed the following tasks **
1. Create a new dynamic database. ( I have used Execute SQL Task to do this) 2. Copy all the table structures ( I have used Execute SQL Task to do this)
3. Import Data. This is the main problem. I was trying to create a dynamic connection string with variables as suggested in several forums but I finally came to know that this cannot be done if the table structures are different as the metadata cannot be refreshed at runtime.
4. The final step to create a process to validate the data (the count from each table for both source and destination. I think this can be done with Sql task.
What is the best method to do this? My DBA does not like “Transfer SQL Objects Task” or “transfer Database Task”. I would like to create this as a dynamic process.

I have two Databases with the same name that reside in different servers. The two servers are linked servers. Each database consists of 5 Tables. The tables have identical names in each database.
The database in ServerA has 5 tables with data, the database in ServerB also has 5 tables with the same schema as ServerA, however the 5 identical tables in ServerB contain no data.
I need to populate the 5 tables in ServerB with the Data from the 5 tables in ServerA.
What SQL code or script can i use to populate the 5 tables in ServerB
Below are the names of the 5 tables:
TABLE1: [ServerB].[ProdDB].dbo.[Orders]
TABLE2: [ServerB].[ProdDB].dbo.[Sales]
TABLE3: [ServerB].[ProdDB].dbo.[Employee]
TABLE4: [ServerB].[ProdDB].dbo.[Customer]
