Question

LookupTable中：

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

移动：

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

我想要一个查询，它将返回以下内容：

firstname，lastname，mobile.name作为mobilename，callednumbers（作为CallLogs表中不同行的连续字符串），需要2000年例如：

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

任何帮助都将受到高度赞赏......

我已经尝试了这个但没有成功..汤姆正在接受调查，反之亦然。我正在使用sql server。

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
