SQL Server - Объединение запросов с соответствующими значениями в двух столбцах

Question

Довольно новый для Sql Server, и я ищу объединение двух запросов при совпадении двух столбцов. Например. Если столбец TimeByDay & ResourceName в запросе Емкость соответствует столбцу TimeByDay и ResourceName в запросе Allocation, затем вытащите значения в Capacity. Любые другие рекомендации приветствуются. Пожалуйста, дайте мне знать, если я не понимаю. Благодарю.

QueryAllocation

ProjectName TaskName ResourceName ResourceManager AssignmentWork TimeBYDay 
Project1  Task1  ResourceA  ManagerA  8    2015-1-1 
Project1  Task2  ResourceB  ManagerB  7.5    2015-1-2 
Project2  Task3  ResourceA  ManagerA  4    2015-1-5 
Project3  Task4  ResourceA  ManagerA  1    2015-1-5 
Project3  Task5  ResourceB  ManagerB  2    2015-1-5 
Project4  Task6  ResourceC  ManagerB  2    2015-1-5 

Запрос

SELECT 
    P.ProjectName, 
    T.TaskName, 
    R.ResourceName, 
    RUV.[Resource Manager], 
    ABD.AssignmentWork, 
    TBD.TimeByDay 

FROM dbo.MSP_TimeByDay TBD 
LEFT JOIN dbo.MSP_EpmAssignmentByDay ABD 
    ON TBD.TimeByday = ABD.TimeByDay 
LEFT JOIN dbo.MSP_EpmAssignment A 
    ON ABD.AssignmentUID = A.AssignmentUID 
LEFT JOIN dbo.MSP_EpmResource R 
    ON A.ResourceUID = R.ResourceUID 
LEFT JOIN dbo.MSP_EpmResource_UserView RUV 
    ON R.ResourceUID = RUV.ResourceUID 
LEFT JOIN dbo.MSP_EpmTask T 
    ON A.TaskUID = T.TaskUID 
LEFT JOIN dbo.MSP_EpmProject P 
    ON T.ProjectUID = P.ProjectUID 

WHERE NOT (ABD.AssignmentUID IS NULL) 

QueryCapacity

ResourceName Capacity TimeByDay 
ResourceA  6   2015-1-1 
ResourceB  4   2015-1-2 
ResourceA  8   2015-1-5 
ResourceB  7   2015-1-5 
ResourceC  7.5   2015-1-5 

Запрос

SELECT 
    R2.ResourceName, 
    RBD2.Capacity, 
    TBD2.TimeByDay 

FROM dbo.MSP_TimeByDay TBD2 
LEFT JOIN dbo.MSP_EpmResourceByDay RBD2 
    ON TBD2.TimeByDay = RBD2.TimeByDay 
LEFT JOIN dbo.MSP_EpmResource R2 
    ON RBD2.ResourceUID = R2.ResourceUID 

WHERE NOT (RBD2.ResourceUID IS NULL) 

Желательные Результаты

ProjectName TaskName ResourceName ResourceManager AssignmentWork TimeBYDay Capacity  
Project1 Task1  ResourceA  ManagerA  8    2015-1-1 6 
Project1 Task2  ResourceB  ManagerB  7.5    2015-1-2 4 
Project2 Task3  ResourceA  ManagerA  4    2015-1-5 8 
Project3 Task4  ResourceA  ManagerA  1    2015-1-5 8 
Project3 Task5  ResourceB  ManagerB  2    2015-1-5 7 
Project4 Task6  ResourceC  ManagerB  2    2015-1-5 7.5

Я не уверен, что схемы и отношения между вашими таблицами, поэтому я беру выстрел в темноте.

Пожалуйста, проверьте, дает ли этот запрос результаты в нужном вам формате.

Вам нужно будет убедиться, что условия соединения не создают ненужных дубликатов из-за использования LEFT JOIN.

SELECT 
    P.ProjectName 
    , T.TaskName 
    , R.ResourceName 
    , RUV.[Resource Manager] 
    , ABD.AssignmentWork 
    , TBD.TimeByDay 
    , RBD.Capacity 
FROM dbo.MSP_TimeByDay TBD 
-- Query Allocation 
LEFT JOIN dbo.MSP_EpmAssignmentByDay ABD ON TBD.TimeByday = ABD.TimeByDay 
LEFT JOIN dbo.MSP_EpmAssignment A ON ABD.AssignmentUID = A.AssignmentUID 
LEFT JOIN dbo.MSP_EpmResource R ON A.ResourceUID = R.ResourceUID 
LEFT JOIN dbo.MSP_EpmResource_UserView RUV ON R.ResourceUID = RUV.ResourceUID 
LEFT JOIN dbo.MSP_EpmTask T ON A.TaskUID = T.TaskUID 
LEFT JOIN dbo.MSP_EpmProject P ON T.ProjectUID = P.ProjectUID 
-- Query Capacity 
LEFT JOIN dbo.MSP_EpmResourceByDay RBD ON TBD.TimeByDay = RBD.TimeByDay 

WHERE NOT (ABD.AssignmentUID IS NULL) AND NOT (RBD.ResourceUID IS NULL)

Спасибо SimplyInk, я не знал, что конструктор запросов можно открыть в SSMS. Я получил желаемые результаты.

SELECT   
dbo.MSP_EpmAssignment.AssignmentUID, dbo.MSP_EpmAssignmentByDay.AssignmentWork, dbo.MSP_EpmAssignmentByDay.TimeByDay, 
dbo.MSP_EpmResourceByDay.Capacity, dbo.MSP_EpmTask.TaskName, dbo.MSP_EpmProject.ProjectName, dbo.MSP_EpmResource.ResourceName, 
dbo.MSP_EpmResource_UserView.[Resource Manager], dbo.MSP_EpmResource_UserView.[Resource Departments], 
dbo.MSP_EpmResource_UserView.[Resource Role], dbo.MSP_EpmResource_UserView.ResourceEarliestAvailableFrom, 
dbo.MSP_EpmResource_UserView.ResourceLatestAvailableTo, dbo.MSP_TimeByDay.TimeMonthOfTheYear, dbo.MSP_TimeByDay.TimeDayOfTheMonth, 
dbo.MSP_TimeByDay.TimeYear 

FROM    
dbo.MSP_EpmAssignment 
INNER JOIN dbo.MSP_EpmAssignmentByDay ON dbo.MSP_EpmAssignment.AssignmentUID = dbo.MSP_EpmAssignmentByDay.AssignmentUID 
INNER JOIN dbo.MSP_EpmResourceByDay ON dbo.MSP_EpmAssignment.ResourceUID = dbo.MSP_EpmResourceByDay.ResourceUID AND
