Rebuilding Index and updating statistics using SQL SMSS

I'm not an expert on SQL, but have to rebuild index and update statistics on a database.

When I search the steps to do, nearly all of them are running manual codes to do it and they are all different.
So, I created a SMSS maintenance plan to do the rebuild index and update statistics. And I will run it on the scheduled maintenance time this Friday. It will probably take a lot of time since I haven't done it for a few years. The reason why it is, because when I run it, it fails. I think it's because users access database. I have to block all connections to SQL server.

Questions:
1.How to block all SQL connections      so that I can do rebuild index and update statistics alone? I have to do this at midnight from home, and can't disconnect network connection, have to block only SQL connections and stay offline.


2.I see an option in the SQL maintenance job I created, but not sure this is the only option I can do.

3.Can I take the database offline by 'SSMS / Tasks/ Take Offline' and rebuild index?

The server is Windows 2012 STD and SQL 2008 STD

This is the best option you have got. Automate it and schedule.

I see an option in the SQL maintenance job I created, but not sure this is the only option I can do.

Hi, Pawan,
I successfully rebuilt index, but the fragmentation level doesn't drop in running this script. Do you know why? I checked one of the table's properties window, it shows 0% fragmented, though. And the Page fullness shows 99%.

Code to check fragmentation;
-- Check fragmentation on db(dbname)

Declare @dbid INT
Set @dbid =DB_ID('dbname')

select dbschemas.[name] as 'Schema', 
                dbtables.[name] as 'Table', 
                dbindexes.[name] as 'Index',
                indexstats.avg_fragmentation_in_percent,
                indexstats.page_count
from sys.dm_db_index_physical_stats (@dbid, NULL, NULL, NULL, NULL) as indexstats
                INNER JOIN sys.tables dbtables on dbtables.[object_id] = indexstats.[object_id]
                INNER JOIN sys.schemas dbschemas on dbtables.[schema_id] = dbschemas.[schema_id]
                INNER JOIN sys.indexes as dbindexes on dbindexes.[object_id] = indexstats.[object_id]
                                AND indexstats.index_id = dbindexes.index_id
where indexstats.database_id = @dbid
order by indexstats.avg_fragmentation_in_percent desc

Open in new window


After rebuildindex finished, two different statistics and page fullness 99%

What's wrong with the Page Fullness? That value you want it to be the nearest from 100% possible.
