Question

我正在运行下面的SQL语句，但最后我需要总计。使用SQL Server

SELECT tblAllocation.Allocation AS TimeSlots, COUNT(*) AS [Applicant Total] 
FROM tblAllocation  
INNER JOIN tblRegistration ON tblAllocation.AllocationID = tblRegistration.AllocationID  
INNER JOIN tblcontact ON tblRegistration.ContactID = tblcontact.ContactID
INNER JOIN tbladdress AS tbladdress_1 ON tblcontact.AddressID = tbladdress_1.AddressID  
INNER JOIN tblNadraRegistrationDates ON tblRegistration.NRegDateID = tblNadraRegistrationDates.NRegDateID  
WHERE (tblNadraRegistrationDates.[Nadra Reg Dates] = '26 April 2015')  
GROUP BY tblAllocation.Allocation;

以下是

TimeSlots       Applicant Total
09:30 to 10:30  3
10:30 to 11:30  10
12:30 to 13:30  11
Reservation     8

TOTAL 32  <--- how can I get this

Answer 1

对WITH ROLLUP语句使用GROUP BY选项：

SELECT 
    CASE 
      WHEN GROUPING(tblAllocation.Allocation) = 1 THEN 'Total' 
      ELSE tblAllocation.Allocation 
    END AS TimeSlots, 
    COUNT(*) AS [Applicant Total] 
FROM 
    tblAllocation  
INNER JOIN 
    tblRegistration ON tblAllocation.AllocationID = tblRegistration.AllocationID  
INNER JOIN 
    tblcontact ON tblRegistration.ContactID = tblcontact.ContactID  
INNER JOIN 
    tbladdress AS tbladdress_1 ON tblcontact.AddressID = tbladdress_1.AddressID  
INNER JOIN 
    tblNadraRegistrationDates ON tblRegistration.NRegDateID = tblNadraRegistrationDates.NRegDateID  
WHERE 
    (tblNadraRegistrationDates.[Nadra Reg Dates] = '26 April 2015')  
GROUP BY 
    tblAllocation.Allocation WITH ROLLUP;

您可能希望对表名使用别名来缩短查询文本，并可能使其更具可读性（但这当然只是一种意见）。

SQL语句使用Group By但需要列Total
