Rebuild and Reorganize Indexes in SQL 2005
This SP rebuilds and reorganizes all indexes in the specified database or all databases. You can run code or generate code. Database will be set in bulk logged mode during processing and set back to normal when finished.
Different SQL Editions are handled. LOB indexes, row and page locking options, number of processors, concurrent users and more are handled. Max processing time, fragmentation and density are some of the parameters for this procedure.

NOTE (see BOL): The defragmentation process is always fully logged,
regardless of the database recovery model setting (see ALTER DATABASE).
@databasename is database to defrag indexes for.
@maxruntime is total allowed runtime in seconds for this job, which is checked after each db and each index has been processed.
-- Example how to rebuild ALL database
EXEC master.dbo.spX_RebuildIndexes_Main
@databasename ='',
@maxfrag = 10.0,
@maxdensity = 75.0,
@online = 1,
@runrebuild = 1,
@LogUsedThresholdGB = 6,
@maxruntime = 3600,
@disklimit = '0.19',
@notdisk1 = 'C',
@notdisk2 = '',
@notdisk3 = '',
@notdisk4 = '',
@maxdop= 1
The SP master.dbo.spX_RebuildIndexes is called by this main SP for each database.
spX_RebuildIndexes will process one index at a time and then check if there is still
time left based on the input parameter @maxruntime (in seconds) before processing the
next index.
The SP only runs on SQL 2005.
This SP rebuild and/or reorganizes all indexexs in the specified database or all databases.
You can run this SP while users are using the database, if you specify @online = 1.
If ONLINE, REBUILD WITH (ONLINE = ON, FILLFACTOR = 90) will be run if possible, else REORGANIZE.
These online options does not hold locks long term and thus will
not block running queries or updates. A relatively unfragmented index can be defragmented
faster than a new index can be built because the time to defragment is related to the amount
of fragmentation. A very fragmented index might take considerably longer to defragment than
to rebuild. In addition, the defragmentation is always fully logged, regardless of the
database recovery model setting (see ALTER DATABASE). The defragmentation of a very
fragmented index can generate more log than even a fully logged index creation.
The defragmentation, however, is performed as a series of short transactions and thus does
not require a large log if log backups are taken frequently or if the recovery model setting
is SIMPLE.
