I’m creating a table with a primary key clustered index. When I’m creating without asc/desc, what is the default sorting order? Which sorting order (ASC or DESC) is more efficient? Here is the sample code.

```
Create table employee (
  Name nvarchar(30),
  City nvarchar(30),
  Dob date,
  Constraint pk_employee primary key clustered
  (Name asc, dob asc)
)
Go

```
