Verschwenkung Tabellen

Question

Ich habe eine Tabelle wie folgt aus:

serialnumber partnb id actual  nominal 
1    1  AGR 15,2176803 15,2 
1    1  APR 5,8060656 5,8 
1    1  DCI 61,9512259 62 
1    43  AGR 15,4178727 15,4 
1    43  APR 7,235779 7,2 
1    43  DCI 52,0080535 52 
2    2  AGR 15,2097009 15,2 
2    2  APR 5,8009968 5,8 
2    2  DCI 61,9582795 62 
2    44  AGR 15,4191387 15,4 
2    44  APR 7,2370065 7,2 
2    44  DCI 52,010244 52

Und ich möchte dies:

serialnumber partnb AGR AGR_nominal APR APR_nominal  DCI DCI_nominal 
1    1 15,217 15,2  5,806 5,8  61,951 62 
1    43 15,417 15,2  7,235 7,2  52,008 62 
2    2 15,209 15,2  5,800 5,8  61,958 62 
2    44 15,419 15,4  7,237 7,2  52,010 52

Wie kann ich das erreichen in SQL Server 2005?

    FROM(SELECT DISTINCT serialnumber, planid, partnb, id, actual FROM vwMeasurement) driver

) AS p 
    ORDER BY planid, serialnumber, partnb

Answer 2

Es gibt wahrscheinlich einen besseren Weg, aber Sie könnten separate Ansichten für AGR, APR und DCI erstellen und sie bei ID verbinden.

Answer 3

Es gibt ein PIVOT-Schlüsselwort in Sql Server 2005, das Sie verwenden können. Hier ist die Beschreibung http://msdn.microsoft.com/en-us/library/ms177410.aspx
