concating columns

this is my DDL:
CREATE TABLE [dbo].[Table1] (
[Code] [int] IDENTITY (1, 1) NOT NULL ,
[Name] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL
,
[ParentCode] [int] NULL
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[Table1] ADD
CONSTRAINT [PK_Table1] PRIMARY KEY CLUSTERED
(
[Code]
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[Table1] ADD
CONSTRAINT [FK_Table1_Table1] FOREIGN KEY
(
[ParentCode]
) REFERENCES [dbo].[Table1] (
[Code]
)
I want to concat Column of Name:
Code Name ParentCode
1 test NULL
2 book NULL
3 Cake 1
4 Mouse 3
I want to concat column of Name for Code=4 and output will be: testCake

SELECT c.[Name] + b.[Name] AS ConcatName
FROM Table1 AS a
JOIN Table1 AS b ON a.ParentCode = b.Code
JOIN Table1 AS c ON b.ParentCode = c.Code
WHERE a.Code = 4|||I want to do that for many levels as is not for 2 rows.

If you are using SQL Server 2005 CTE with recursive query.
with temp as
(select convert(varchar(50),'') + convert(varchar(50),'')
name ,parentcode,code from table1 where code =4
union all
select convert(varchar(50),t1.name)+convert(varchar(50),t.name) as
name ,t1.parentcode,t1.code
from table1 t1 inner join temp t on t.parentcode = t1.code)
select name from temp where parentcode is null
