Rebuilding All Indexes on One Table in SQL Server
How To Rebuild All Indexes on a Single Table in SQL Server?
✍: FYIcenter.com
If you have several indexes on a single table and want to rebuild all of them, you may use the "ALTER INDEX ALL ON table_name REBUILD" statement as shown in the tutorial exercise below:
USE FyiCenterData;
GO
UPDATE fyi_links_indexed
SET url = REVERSE(url), counts = -counts
WHERE id <=50000;
GO
(50000 row(s) affected)
SELECT i.index_id, i.name, s.avg_fragmentation_in_percent
FROM sys.dm_db_index_physical_stats (
DB_ID(N'FyiCenterData'),
OBJECT_ID(N'fyi_links_indexed'),
DEFAULT, DEFAULT, DEFAULT) s, sys.indexes i
WHERE s.object_id = i.object_id
AND s.index_id = i.index_id;
GO
0 NULL 0.574712643678161
2 fyi_links_url 85.750315258512
3 fyi_links_counts 84.040404040404
ALTER INDEX ALL ON fyi_links_indexed REBUILD;
GO
SELECT i.index_id, i.name, s.avg_fragmentation_in_percent
FROM sys.dm_db_index_physical_stats (
DB_ID(N'FyiCenterData'),
OBJECT_ID(N'fyi_links_indexed'),
DEFAULT, DEFAULT, DEFAULT) s, sys.indexes i
WHERE s.object_id = i.object_id
AND s.index_id = i.index_id;
GO
0 NULL 0.574712643678161
2 fyi_links_url 0.12987012987013
3 fyi_links_counts 0.448430493273543
Both indexes were defragmented to a very low level now.
