分配给SQL Server中表的未使用空间

Question

I have a table in my Database which has unused space of about 55GB. How do I reduce this unused space?

Steps that I have tried:

1. I have rebuilt the Indexes, this helped me a lot this reduced the unused space from 110GB to 55GB.
2. By running DBCC SHOWCONTIG I found that my table's average page density is 99% (which is in a way good,but it did not help me to reduce the unused space)
3. I have changed the fill factor and rebuild the index again (this time rebuilding the index after changing fill factor to 100 did not reflect any desired outcome)
4. I tried DBCC CLEANTABLE (DBNAME,"Tablename"), I could not reduce the unused space
5. I have not tried shrinking of DB, I want to reduce the unused space without shrinking the DB.

Current output:

Desired Output: I want to reduce the Total space so that the Unused space is reduced.

Answer 1

Create a new table and then export the data to this new table.

SELECT * INTO newtable FROM table -- or copy wizard (by SSMS)

And then, drop the old table, but make you sure that the all data was transferred successfully.

Answer 2

解：

ALTER INDEX ALL ON MyTable REBUILD WITH (FILLFACTOR = 100);
