Please help - Joining three tables and get row values into Column. Please help!

Question

Hi,
There is a SourceTable1 (Employee) with Columns like EmployeeID,Name,DOB.
There is a sourcetable2 (EmployeeCode) with columns like EmployeeID,Code,Order.
There is a source table 3  #EmployeeRegioncode  and its columns are (EmployeeID , RegionCode , [Order] 
The target table 'EmployeeDetails' has the following details. EmployeeID,Name,DOB,Code1,Code2,Code3,Code4,regioncode1
regioncode2 ,regioncode3 ,regioncode4 
The requirement is , the value of the target table columns the Code1,code2,code3 ,code4,code5 values should
be column 'Code' from Sourcetable2 where its 'Order' column is accordingly. ie) Code1 value should be the 'Code' value where [Order] column =1, and Code2 value should be the 'Code' value where [Order] =2, and so on.
Same is the case for Source table 3- 'Region code' column also for the columns  regioncode1
regioncode2 ,regioncode3 ,regioncode4 
Here is the DDL and Sample date for your ref.
IF OBJECT_ID('TEMPDB..#Employee') IS NOT NULL DROP TABLE #Employee;
IF OBJECT_ID('TEMPDB..#EmployeeCode') IS NOT NULL DROP TABLE #EmployeeCode;
IF OBJECT_ID('TEMPDB..#EmployeeDetails') IS NOT NULL DROP TABLE #EmployeeDetails;
---Source1
CREATE table #Employee 
(EmployeeID int, Empname varchar(20), DOB date )
insert into #Employee VALUES (1000,'Sachin','1975-12-12') 
insert into #Employee VALUES (1001,'Sara','1996-12-10') 
insert into #Employee  VALUES (1002,'Arjun','2000-12-12')

insert into #EmployeeCode  VALUES  (1002,'DDDD',4)  
insert into #EmployeeCode  VALUES  (1002,'EEEE',5)  
---Source tbl 3
CREATE table #EmployeeRegioncode 
(EmployeeID int, RegionCode varchar(10), [Order] int)
insert into #EmployeeRegioncode VALUES (1000,'xx',1) 
insert into #EmployeeRegioncode VALUES (1000,'yy',2)

insert into #EmployeeRegioncode  VALUES  (1001,'xy',4)  
insert into #EmployeeRegioncode  VALUES  (1002,'qq',1)  
insert into #EmployeeRegioncode  VALUES  (1002,'rr',2)  
insert into #EmployeeRegioncode  VALUES  (1002,'ss',3)  
---Target
Create table #EmployeeDetails
(EmployeeID int, Code1 varchar(10), Code2 varchar(10),Code3 varchar(10),Code4 varchar(10),Code5 varchar(10) , regioncode1 varchar(10),
regioncode2 varchar(10),regioncode3 varchar(10),regioncode4 varchar(10))
insert into #EmployeeDetails  VALUES (1000,'AA','BB','CC','','','xx','yy','zz','')  
insert into #EmployeeDetails  VALUES (1001,'AAA','BBB','CCC','DDD','','xx','yy','zz','xy')  
insert into #EmployeeDetails VALUES (1002,'AAAA','BBBB','CCCC','DDDD','EEEE','qq','rr','ss','')  
SELECT * FROM  #Employee
SELECT * FROM  #EmployeeCode
SELECT * FROM  #EmployeeRegioncode
SELECT * FROM  #EmployeeDetails
Can you please help me to get the desired /targetoutput?  I have sql server 2008.
Your help is greatly appreciated.

select a.EmployeeID,b.code1,b.code2,b.code3,b.code4,b.code5,c.Reg1,c.Reg2,c.Reg3,c.Reg4 from
#Employee a
left outer join
(select EmployeeID,max(case when [Order] =1 then Code else '' end) code1,
max(case when [Order] =2 then Code else '' end)code2,
max(case when [Order] =3 then Code else '' end)code3,
max(case when [Order] =4 then Code else '' end)code4,
max(case when [Order] =5 then Code else '' end)code5 from #EmployeeCode group by EmployeeID) b
on a.EmployeeID=b.EmployeeID
left outer join
(select EmployeeID,max(case when [Order] =1 then RegionCode else '' end) Reg1,
max(case when [Order] =2 then RegionCode else '' end)Reg2,
max(case when [Order] =3 then RegionCode else '' end)Reg3,
max(case when [Order] =4 then RegionCode else '' end)Reg4 from #EmployeeRegioncode group by EmployeeID) c
on a.EmployeeID=c.EmployeeID
