How To Create Two Separate Fields From The Data?

Can anyone please help me with the following:


I have a table which has fields called defid, datavalue, pid etc.
I have to create a new table which should have fields:
CustID, datavalue[SocSec]{note:this is the value in d.datavalue when defid is 1004), datavalue[FirstName]{note: this is the value in d.datavalue when defid is 1006}, datavalue[LastName]{note: this is the value in d.datavalue when defid is 1007}, [FullName] {note: this is the value I should get by joining the datavalues (lastname and firstname) when defifis 1006 and 1007) ie. ex: FirstNameLastName.

COULD ANYONE PLEASE HELP ME ON THIS. DATA QUERY is as follows:
Thank you in advance.

SELECT DISTINCT c.CustID, d.datavalue, f.name
FROM dbo.Customers c
INNER JOIN dbo.Date7 d ON d.pid = c.root
INNER JOIN dbo.fielddisc f ON f.defid = d.defid
WHERE c.separatedate BETWEEN @StartDate AND @EndDate
AND c.DateTab = 7 AND d.defid IN (1004, 1006, 1007, 1009) AND c.CustID = 10 AND c.root = 8472
ORDER BY c.root
