Index Maintenance is one of the major task for a DBA. If rate of Index fragmentation increased then index de-fragmentation is become required. So we can use index reorganize option to rebuild all the indexes. Use Index reorganize option when rate of index fragmentation is b/w 10% to 40%.
Syntax:
Alter Index All On Table_Name Reorganize.
Example:
ALTER INDEX ALL ON geographicals Reorganize
GO
Rebuild Index for All tablex in database:
Exec sp_msforeachtable 'ALTER INDEX ALL ON ? Reorganize'
GO
