Question

Table 1 contains certain set of data's. I need to get the following result set form the Table 1

Table1

Id  Desc          ParentId
1   Cloths            0
2   Mens              1
3   Womens            1
4   T-Shirt_M         2
5   Casual Shirts_M   2
6   T-Shirt_F         3
7   Education         8

If I pass a parameter as "Casual Shirts_M" I should get the below result set.

Result Set

Id  Desc          ParentId
1   Cloths            0
2   Mens              1
5   Casual Shirts_M   2

Answer 1

As mentioned in comments, there are plenty of Recursive Common Table Expressions examples for this, here's another one

DECLARE @Desc NVARCHAR(50) = 'Casual Shirts_M'
;WITH cteX
AS
(   SELECT
        B.Id, B.[DESC], B.ParentId
    FROM
        Table1 b
    WHERE
        B.[Desc] = @Desc
    UNION ALL
    SELECT
        E.Id, E.[DESC], E.ParentId
    FROM
        Table1  E
    INNER JOIN
        cteX r ON e.Id = r.ParentId
)
SELECT * FROM cteX ORDER BY ID ASC

The question comes under the concept of Building hierarchy using Recursive CTE:

 CREATE TABLE cloths 
  ( 
     id       INT, 
     descr    VARCHAR(100), 
     parentid INT 
  ); 


insert into cloths values (1,'Cloths',0);
insert into cloths values (2,'Mens',1);
insert into cloths values (3,'Womens',1);
insert into cloths values (4,'T-Shirt_M',2);
insert into cloths values (5,'Casual Shirts_M',2);
insert into cloths values (6,'T-Shirt_F',3);
insert into cloths values (7,'Education',8);


DECLARE @variety VARCHAR(100) = 'Casual Shirts_M'; 

WITH 
cte1 (id, descr, parentid) 
     AS (SELECT * 
         FROM   cloths 
         WHERE  descr = @variety 
         UNION ALL 
         SELECT c.id, 
                c.descr, 
                c.parentid 
         FROM   cloths c 
                INNER JOIN cte1 r 
                        ON c.id = r.parentid) 
SELECT * 
FROM   cte1 
ORDER  BY parentid ASC;
