Complicato query a campi incrociati domanda

Question

Ho i seguenti 2 tabelle:

1) Società

ID      CompanyName      Abbreviation     Notes  
1        CompanyA             CA          ...  
2        CompanyB             CB          ...  
3        CompanyC             CC          ...

2) PlannedDeployments

ID      CompanyID      TypeID      DepDate      NumDeployed  
1          1             2         09/2010          5  
2          1             2         10/2010          5
3          1             3         09/2010          3
4          1             3         10/2010          3
5          1             4         10/2010          4
6          2             2         12/2010          10
7          2             4         10/2010          1
8          3             2         11/2010          6

Si noti che TypeID è un numero tra 1 e 5 descrive che tipo di persona viene distribuito. Ai fini della presente interrogazione, mi interessa dipendenti Type2 per ciascuna società e quindi la somma dei tipi 3 e 4 per ogni data. Quello che alla fine voglio finire con è un campo incrociato che appare come il seguente:

a campi incrociati

Date/Company    CompanyA    CompanyB    CompanyC     SumOfTypes3and4
09/2010            5                                        3
10/2010            5                                        8
11/2010                                    6                
12/2010                        10

Il problema è che colonna finale - la somma di tipo 3 e tipo 4 dipendenti. Il campo incrociato corrente che ho comprende tutto tranne quella colonna somma e si presenta come il seguente:

TRANSFORM Sum(PlannedDeployments.NumDeployed) AS ["NumDeployed"]
SELECT PlannedDeployments.DepDate
FROM PlannedDeployments LEFT JOIN Companies ON Companies.ID=PlannedDeployments.CompanyID
WHERE PlannedDeployments.TypeID=2 AND (PlannedDeployments.DepDate Between FormFieldValue("Form", "Control") AND FormFieldValue("Form", "Control"))
GROUP BY PlannedDeployments.DepDate
PIVOT Companies.CompanyName;

La seconda parte di tale clausola WHERE è solo limitando i dati da alcuni controlli modulo. In ogni caso - Sto avendo un sacco di problemi a trovare quella colonna finale. Qualcuno ha qualche idea?

Modifica: Costruire sulla soluzione fornita da Remou di seguito, ecco quello che la domanda finale ha finito per assomigliare:

TRANSFORM Sum(PlannedDeployments.NumDeployed) AS ["NumDeployed"]
SELECT PlannedDeployments.DepDate, q.SumOfNumDeployed
FROM (SELECT PlannedDeployments.DepDate, Sum(PlannedDeployments.NumDeployed) AS SumOfNumDeployed
FROM PlannedDeployments
WHERE (((PlannedDeployments.[TypeID]) In (3,4)))
GROUP BY PlannedDeployments.DepDate) AS q 
RIGHT JOIN (PlannedDeployments 
INNER JOIN Companies ON PlannedDeployments.CompanyID = Companies.ID) 
ON q.DepDate = PlannedDeployments.DepDate
WHERE PlannedDeployments.TypeID=2 
   AND (PlannedDeployments.DepDate Between FormFieldValue("Form", "Control") 
   AND FormFieldValue("Form", "Control"))
GROUP BY PlannedDeployments.DepDate, q.SumOfNumDeployed
PIVOT Companies.CompanyName;

Answer 1

È possibile utilizzare una sottoquery:

TRANSFORM Sum(PlannedDeployments.NumDeployed) AS ["NumDeployed"]
SELECT PlannedDeployments.DepDate, Sum(q.SumOfNumDeployed) AS SumOfSumOfNumDeployed
FROM (SELECT PlannedDeployments.DepDate, Sum(PlannedDeployments.NumDeployed) AS SumOfNumDeployed
FROM PlannedDeployments
WHERE (((PlannedDeployments.[TypeID]) In (3,4)))
GROUP BY PlannedDeployments.DepDate) AS q 
RIGHT JOIN (PlannedDeployments 
INNER JOIN Companies ON PlannedDeployments.CompanyID = Companies.ID) 
ON q.DepDate = PlannedDeployments.DepDate
WHERE PlannedDeployments.TypeID=2 
   AND (PlannedDeployments.DepDate Between FormFieldValue("Form", "Control") 
   AND FormFieldValue("Form", "Control"))
GROUP BY PlannedDeployments.DepDate
PIVOT Companies.CompanyName;
