Retrieve Manager/Subordinate Hierarchy From Self-Referencing Table

Hi SQL Gurus

Could anyone please explain how the following stored procedure can be
amended to retrieve Subordinates in alphabetical order ?

The example below simply retrives records in the order in which they
were entered.

It sounds very easy but I can't sort it out ?

The following code was taken from Narayana Vyas Kondreddi's website
(http://vyaskn.tripod.com/index.htm)

Consider the employee table of an organization, that stores all the
employee records. Each employee is linked to his/her manager by a
manger ID.


CREATE TABLE dbo.Emp
(
EmpIDintPRIMARY KEY,
EmpNamevarchar(30),
MgrIDintFOREIGN KEY REFERENCES Emp(EmpID)
)
GO

CREATE NONCLUSTERED INDEX NC_NU_Emp_MgrID ON dbo.Emp(MgrID)
GO

INSERT dbo.Emp SELECT 1, 'President', NULL
INSERT dbo.Emp SELECT 2, 'Vice President', 1
INSERT dbo.Emp SELECT 3, 'CEO', 2
INSERT dbo.Emp SELECT 4, 'CTO', 2
INSERT dbo.Emp SELECT 5, 'Group Project Manager', 4
INSERT dbo.Emp SELECT 6, 'Project Manager 1', 5
INSERT dbo.Emp SELECT 7, 'Project Manager 2', 5
INSERT dbo.Emp SELECT 8, 'Team Leader 1', 6
INSERT dbo.Emp SELECT 9, 'Software Engineer 1', 8
INSERT dbo.Emp SELECT 10, 'Software Engineer 2', 8
INSERT dbo.Emp SELECT 11, 'Test Lead 1', 6
INSERT dbo.Emp SELECT 12, 'Tester 1', 11
INSERT dbo.Emp SELECT 13, 'Tester 2', 11
INSERT dbo.Emp SELECT 14, 'Team Leader 2', 7
INSERT dbo.Emp SELECT 15, 'Software Engineer 3', 14
INSERT dbo.Emp SELECT 16, 'Software Engineer 4', 14
INSERT dbo.Emp SELECT 17, 'Test Lead 2', 7
INSERT dbo.Emp SELECT 18, 'Tester 3', 17
INSERT dbo.Emp SELECT 19, 'Tester 4', 17
INSERT dbo.Emp SELECT 20, 'Tester 5', 17
GO

CREATE PROC dbo.ShowHierarchy
(
@Root int
)
AS
BEGIN
SET NOCOUNT ON
DECLARE @EmpID int, @EmpName varchar(30)

SET @EmpName = (SELECT EmpName FROM dbo.Emp WHERE EmpID = @Root)
PRINT REPLICATE('-', @@NESTLEVEL * 4) + @EmpName

SET @EmpID = (SELECT MIN(EmpID) FROM dbo.Emp WHERE MgrID = @Root)

WHILE @EmpID IS NOT NULL
BEGIN
EXEC dbo.ShowHierarchy @EmpID
SET @EmpID = (SELECT MIN(EmpID) FROM dbo.Emp WHERE MgrID = @Root AND
EmpID > @EmpID)
END
END
GO


EXEC dbo.ShowHierarchy 1
GO
