SQL Query /stored procedure to get complete organization hierarchy detail - sql-server-2008

Question

I tried and searched the solution for the below problem statement but unfortunately I didn't get the exact output. I need to display the complete organizational hierarchy in the below format. I tried with using CTE with UNION ALL but still I'm unable to get the exact output.
Table structure:
CREATE TABLE EMPMASTER
(
EMPID CHAR(10),
EMPNAME NVARCHAR(50),
EMPDESIG VARCHAR(20),
MRGID CHAR(10)
);
Output:
EMPNAME EMPID EMP DESIGNATION
------------------------------------
EMP1 00001 CEO
EMP2 00009 MANAGER 1
EMP3 00005 TL1
EMP4 00003 SSD1
EMP5 00006 SD1
EMP6 00008 TL2
EMP7 00020 SSD2
EMP8 25 SD2
EMP9 00030 TL3
EMP10 00017 MANAGER2
EMP11 00029 TL4
EMP12 00045 SSD3
EMP13 00060 SSD4
EMP14 00070 SD3
EMP15 00060 SD4
EMP16 00090 SD5
EMP17 00055 SD6
CONTI… CONTI… CONTI…
Code that I tried:
WITH HierarchyTree (EMPID, EMPNAME, EMPDESIG, MRGID, Rank)
AS
(
-- Anchor member definition
SELECT
EMPID, EMPNAME, EMPDESIG, MRGID, 0 AS Rank
FROM
EMPMASTER AS e
WHERE
DESIGNATION = 'Admin' AND EMPLOYEE_ID='1'
UNION ALL
-- Recursive member definition
SELECT
e.EMPID, e.EMPNAME, e.EMPDESIG, e.MRGID, Rank + 1
FROM
EMPMASTER AS e
INNER JOIN
HierarchyTree AS d ON e.REPORTINGTO = d.EMPLOYEE_ID
)
SELECT
EMPID, EMPNAME, DESIGNATION, REPORTINGTO, Rank
FROM
HierarchyTree
Sample data
EMPID EMPNAME EMPDESIG MRGID
1 RAM CEO 0
7326 MOHD RAFI MANAGER 7454
7454 PMT PHARMA MANAGER 1
2094 VAC SANJAY DEVELOPER 14005
602 GS MANAGER 7454
412 RAJESH LEAD 602
14005 VAC SM N LEAD 7326
34395 DEEPAK LEAD 7326
16430 VIJAY DEVELOPER 34395

Answer 1

I would venture to suggest an answer based on the hierarchy diagram:
declare #EMPMASTER table
(
EMPID CHAR(10) ,
EMPNAME NVARCHAR(50) ,
EMPDESIG VARCHAR(20) ,
MRGID CHAR(10)
);
insert into #EMPMASTER values
( '00001', 'EMP1', 'CEO', null ),
( '00002', 'EMP2', 'MANAGER1', '00001' ),
( '00003', 'EMP3', 'TL1', '00002' ),
( '00004', 'EMP4', 'SSD1', '00003' ),
( '00005', 'EMP5', 'SD1', '00004' ),
( '00006', 'EMP6', 'TL2', '00002' ),
( '00007', 'EMP7', 'SSD2', '00006' ),
( '00008', 'EMP8', 'SD2', '00007' ),
( '00009', 'EMP9', 'TL3', '00002' ),
( '00010', 'EMP10', 'MANAGER2', '00001' ),
( '00011', 'EMP11', 'TL4', '00010' ),
( '00012', 'EMP12', 'SSD3', '00011' ),
( '00013', 'EMP13', 'SSD4', '00011' ),
( '00014', 'EMP14', 'SD3', '00013' ),
( '00015', 'EMP15', 'SD4', '00013' ),
( '00016', 'EMP16', 'SD5', '00013' ),
( '00017', 'EMP17', 'SD6', '00013' ),
( '00018', 'EMP18', 'MANAGER3', '00001' ),
( '00019', 'EMP19', 'TL5', '00018' ),
( '00020', 'EMP20', 'SSD5', '00019' ),
( '00021', 'EMP21', 'SSD6', '00019' ),
( '00022', 'EMP22', 'SD7', '00021' ),
( '00023', 'EMP23', 'SD8', '00021' ),
( '00024', 'EMP24', 'TL6', '00018' ),
( '00025', 'EMP25', 'SSD7', '00024' );
with cte as
(
select

EMPNAME ,
EMPDESIG ,
MRGID ,
LEVEL = 0,
PATH = cast(EMPDESIG as varchar(8000))
from
#EMPMASTER
where
MRGID is null
UNION ALL
select
t.EMPID ,
t.EMPNAME ,
t.EMPDESIG ,
t.MRGID ,
LEVEL = cte.LEVEL + 1,
PATH = cast(cte.PATH + ' > '+ t.EMPDESIG as varchar(8000))
from

inner join cte on cte.EMPID = t.MRGID
)
select

The same but with the provided data samples:
declare #EMPMASTER table
(
EMPID CHAR(10) ,
EMPNAME NVARCHAR(50) ,
EMPDESIG VARCHAR(20) ,
MRGID CHAR(10)
);
insert into #EMPMASTER values
('1' , 'RAM' , 'CEO' , '0' ),

('7454' , 'PMT PHARMA' , 'MANAGER' , '1' ),
('2094' , 'VAC SANJAY' , 'DEVELOPER' , '14005' ),
('602' , 'GS' , 'MANAGER' , '7454' ),
('412' , 'RAJESH' , 'LEAD' , '602' ),
('14005' , 'VAC SM N' , 'LEAD' , '7326' ),
('34395' , 'DEEPAK' , 'LEAD' , '7326' ),
('16430' , 'VIJAY' , 'DEVELOPER' , '34395' );
with cte as
(
select
EMPID ,
EMPNAME ,
EMPDESIG ,
MRGID ,
LEVEL = 0,
PATH = cast(EMPDESIG + ' (' + EMPNAME +')' as varchar(8000))
from
#EMPMASTER
where
MRGID = '0'
UNION ALL
select
t.EMPID ,
t.EMPNAME ,
t.EMPDESIG ,
t.MRGID ,
LEVEL = cte.LEVEL + 1,
PATH = cast(cte.PATH + ' > ' + t.EMPDESIG + ' (' + t.EMPNAME +')' as varchar(8000))
from
#EMPMASTER t
inner join cte on cte.EMPID = t.MRGID
)
select
EMPID ,
