Hi,
I need to convert this Access SQL command to SQL SERVER COMMAND - I try to llok for examples in the Internet but non of them
had the same logic as here


"TRANSFORM First(tblStudentsMeetingsRelation.studentStatus) AS FirstOfstudentStatus
SELECT tblStudentsMeetingsRelation.studentId, tblStudents.studentFirstName, tblStudents.studentLastName
FROM tblStudents INNER JOIN tblStudentsMeetingsRelation ON tblStudents.studentId = tblStudentsMeetingsRelation.studentId
WHERE (((tblStudentsMeetingsRelation.studentDeptId)="372") AND ((tblStudentsMeetingsRelation.studentSeminarId)="372-3-3455-B"))
GROUP BY tblStudentsMeetingsRelation.studentId, tblStudents.studentFirstName, tblStudents.studentLastName
PIVOT tblStudentsMeetingsRelation.studentMeetingId;"

I will glad if Someone will help me with that

This is the Originl Table :
studentId | studentDeptId | studentSeminarId | studentMeetingId | studentStatus
----------------------------------------------------------------------------------------
40223059 | 372 | 372-3-3455-B | 372-1-05112010 | A
40223059 | 372 | 372-3-3455-B | 372-2-05112010 | DDD
40223059 | 372 | 372-3-3455-B | 372-3-05112010 | C
43162007 | 372 | 372-3-3455-B | 372-1-05112010 | A
43162007 | 372 | 372-3-3455-B | 372-2-05112010 | B
43162007 | 372 | 372-3-3455-B | 372-3-05112010 | C

And the result i'm looking for look like this:

studentId | studentFirstName | studentLastName | 372-1-05112010 | 372-2-05112010 | 372-3-05112010
----------------------------------------------------------------------------------------------------------------------
40223059 | ???? | ???? | A | DDD | C
43162007 | ??? | ?????? | A | B | C

[code]select studentId
, null as studentFirstName
, null as studentLastName
, max(case when studentMeetingId = '372-1-05112010' then studentStatus else null end) as [372-1-05112010]
, max(case when studentMeetingId = '372-2-05112010' then studentStatus else null end) as [372-2-05112010]
, max(case when studentMeetingId = '372-3-05112010' then studentStatus else null end) as [372-3-05112010]
from StudentTable
group by studentId[/code]

or use pivot if using sql 2005 or more


SELECT studentId, studentFirstName , studentLastName,[372-1-05112010],[372-2-05112010],[372-3-05112010]
FROM (SELECT studentId, studentFirstName , studentLastName  , studentMeetingId, studentStatus 
      FROM Table)t
PIVOT (MAX(studentStatus) FOR studentMeetingId IN ([372-1-05112010],[372-2-05112010],[372-3-05112010]))p
