Hi Pinal,

The above command will run one table competes the rebuild and then the other table or all the tables at a time or index by index of the with in the table.

Thanks

Hi pinaldave,
i’ve scheduled a sql2005job with only one step that is:
”
USE eusebi
GO
EXEC sp_MSforeachtable@command1=”print ‘?’ DBCC DBREINDEX (‘?’, ‘ ‘, 80)”
GO
EXEC sp_updatestats
GO
”

the story starts regularly but i obtain for the first line the error:
”
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near ‘=’.
”

why???

tnx

[...] ReIndexing Database Tables and Update Statistics on Tables This blog post written with keeping SQL Server 2000 in mind and uses older syntax of DBREINDEX. SQL SERVER 2005 uses ALTER INDEX syntax to reindex database. SQL SERVER 2005 supports DBREINDEX but it will be deprecated in future versions. [...]

Hi Pinal,
I am using SQL server 2000 database and size of the table is 128 GB. We ask our team to done DBCC reindex on one table size 128 GB with 30 Index. We started this process 20 hrs. before but it is still running also we are not getting any idea whether we need kill it or cancel it. We want to resume our operation before 24 hrs. and not sure how much indexing has been completed on this database table.

Please respond ASAP.

One of the Stored Procedures was taking around 17 Minutes to run and now after following the Re-Indexing Method it takes 3 Secs only!!!

Thanks for the article.

Really good method for reducing dimension of a database which had a lot of insert/delete/update. It’s working in my SQL Server 2008 R2.

Should this be copied and pasted to the query without editing? I got this message after execution, with no apparent changes made. Should ‘MyDatabase’ be edited to my database name?

Msg 911, Level 16, State 1, Line 1
Could not locate entry in sysdatabases for database ‘MyDatabase’. No entry found with that name. Make sure that the name is entered correctly.
[dbo].[Event_Classes]

Does anyone know how long does this task take to run and does it use much CPU / Memory?

Pinal Dave

You are the man, you really helped. I spend more than two days trying to find out what the problem was with my queries, little did i know that I needed to reindex my database tables and then update the statistics.

You are one great DBA, I must say

1. Run the following command. Focus on the “avg_fragmentation_in_percen”, Higher the number on this column, these are table you need to consider rebuilding / reorganize index

SELECT * FROM sys.dm_db_index_physical_stats (NULL, NULL, NULL, NULL, NULL);
GO

2. Once you identfied the index with a higer number on the “avg_fragmentation_in_percen” column

3. Do some reading on Rebuild Index VS Reorganise

I don’t want to give you all the answers, the only way is you finding the best way…. hope the above hints are helpful

I have a very basic question to ask you all, can any one explain the concept of re-indexing, why and how it is related with the performance of database or exactly what makes the db perform faster after re-indexing??

Thanks Sagar
