Jr. DBA asked me three times in a day, how to create Clustered Primary Key. I gave him following sample example. That was the last time he asked “How to create Clustered Primary Key to table?”
USE [AdventureWorks]
GO
ALTER TABLE [Sales].[Individual]
ADD CONSTRAINT [PK_Individual_CustomerID]
PRIMARY KEY CLUSTERED
(
[CustomerID] ASC
)

Wow. Whoever needs this information shouldn’t be allowed near a database.
If i am not wrong please clear me .
I know that if you create primary key in a table it uses a clustered index default,
So why we need to create Clustered primary Key ?
I am bit confused about this matter please help me out.
@Gaurab Chatterjee
You don’t need it. It is there so the code can be explicit, like any default. This might be helpful when CREATEing other TABLEs as well where the PK is not CLUSTERED.
