Wie zwei Daten nebeneinander angezeigt werden?

Question

Ich habe die SLQ unten, um ein Datum auszuwählen, aber ich möchte zwei Daten nebeneinander sehen. Wie kann ich das machen?

Delete From Variance_Analysis 

INSERT INTO Variance_Analysis 
SELECT PIDs.Product_Group, 
     PIDs.PID, 
     PIDs.PID_Name, 
     SUM(MaturityValue) Current_Balance, 
     AsOfDate as Current_Date 
FROM [TBL_PIDs] AS PIDs INNER JOIN RAW_DATA_HIST AS RawData 
    ON PIDs.PID = RawData.PID 
Where AsOfDate = '2017-10-31' 
GROUP BY Product_Group, 
     PIDs.PID, 
     PIDs.PID_Name, 
     AsOfDate 

Wie Sie sehen können, lösche ich die Tabelle, und dann einige IDs und ein Datum einfügen (während Kontosalden Summieren). Ich brauche ein anderes Datum und summiere die entsprechenden Salden. Dann möchte ich die absolute Differenz und die relative Differenz finden, aufgeteilt in 3 Felder. Ich bin mit SQL Server 2008.

-- Step1: 
CREATE TABLE test_table (
    Product_Group varchar(255), 
    PID varchar(10), 
    PID_Name varchar(255), 
    maturityValue decimal(18,2), 
    AsofDate date, 
    Portfolio varchar(255) 
); 


-- Step2: 
INSERT INTO test_table (Product_Group,PID,PID_Name,maturityValue,AsofDate,Portfolio) 
VALUES ('Invt','I.B.7','Investments',1258.69,'9/29/2017','Holding') 
INSERT INTO test_table (Product_Group,PID,PID_Name,maturityValue,AsofDate,Portfolio) 
VALUES ('Asse','A.Q.7','Assets',1263.28,'9/29/2017','Holding') 
INSERT INTO test_table (Product_Group,PID,PID_Name,maturityValue,AsofDate,Portfolio)
