A filtered index eliminates unusable entries from the index, producing an index that is as beneficial as, but much smaller than, an unfiltered index. If a certain subset of a table's data is frequently requested, a filtered index can also be a covering index; resulting in a considerable reduction in IO.

A nonclustered index entry consists of search key columns, included columns, and the bookmark. The bookmark value will be either a RID or the clustered index's key, depending upon whether the table is a heap or a clustered index. Choosing the best clustered index for a table requires that you follow three guidelines to ensure that the index key will make a good bookmark.

I have added a few indexes to one of my tables in SQL Server 2025:
ALTER TABLE dbo.CustomerContact
ADD CONSTRAINT PK_CustomerContact
PRIMARY KEY (CustomerID);
-- Create index on CustomerEmail
CREATE INDEX IX_CustomerContact_CustomerEmail
ON dbo.CustomerContact (CustomerEmail);
CREATE INDEX IX_CustomerContact_CustomerPhone
ON dbo.CustomerContact (phone);
I then do this to disable one index:
alter index IX_CustomerContact_CustomerPhone on dbo.CustomerContact disableI see this when I check the index status:
I decide to rebuild all indexes with this command:
ALTER INDEX ALL ON dbo.CustomerContact rebuildAfter I do this, what will I see for the index status? See possible answers
