ID int not null,
Name nvarchar(16),
Major nvarchar(16));
go
create index ix_for_Student_ID
on dbo.student(ID);
go
create clustered index ix_clu_for_Student_Name
on dbo.Student(Name);
go
select OBJECT_NAME(ix.object_id),ix.index_id,ix.name from sys.indexes as ix
where ix.object_id = object_id('Student');
go
