（Not）複雑なSQLクエリ！

Question

ルックアップテーブル：

userid, mobileid, startedate, enddate , owner 
1  , 1  , 12-12-2000, 01-01-2001, asd 
2  , 2  , 12-12-2000, 01-01-2001, dgs 
3  , 3  , 02-01-2001, 01-01-2002, sdg 
4  , 4  , 12-12-2000, 01-01-2001, sdg 

UserInfoTable：

userid, firstname, lastname, address 
1  , tom  , do  , test 
2  , sam  , smith , asds 
3  , john  , saw  , asdasda 
4  , peter , winston , near by 

モバイル：

Mobileid, Name  , number, imeinumber 
1  , apple  , 123 , 1111111 
2  , nokia  , 456 , 2222222 
3  , vodafone , 789 , 3333333 

CallLogs：

id  , Mobileid, callednumbers (string), date   , totalduration 
1  , 1  , 123,123,321   , 13-12-2000 , 30 
2  , 1  , 123,123,321   , 14-12-2000 , 30 
3  , 2  , 123,123,321   , 13-12-2000 , 30

8  , 1  , 123,123,321   , 14-01-2002 , 30 

私は私にFOLを返しますクエリをしたいですlowing：

ファーストネーム、姓、mobilenameとしてmobile.name、（CallLogsテーブル内の異なる行からの連接文字列として）callednumbersと たとえば2000年のためにそれを必要とする：

firstname, lastname, mobilename, callednumbers 
tom  , do  , apple  , 123,123,321, 123,123,321 
sam  , smith , nokia  , 123,123,321, 123,123,321 
peter , winston , apple  , 123,123,321, 123,123,321 

任意のヘルプは高く評価されます...

私はこれを試しましたが、成功していません..トムはsams呼び出しを受け取り、その逆もあります。私はSQL Serverを使用しています。

SELECT DISTINCT firstname, 
       lastname, 
       mobilename, 
       callednumbers 
FROM ([testdatabase].[dbo].[LookupTable] lt 
     INNER JOIN [testdatabase].[dbo].[UserInfoTable] user1 
      ON lt.userid = user1.id) 
     INNER JOIN [testdatabase].[dbo].[Mobile] device1 
     ON lt.mobileid = device1.id 
     INNER JOIN [testdatabase].[dbo].[CallLogs] log1 
     ON lt.mobileid = log1.deviceid 
WHERE lt.starttime LIKE '%2000%' 
ORDER BY firstname
