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
