SQL QUERY HELP

I have the following table.

CREATE TABLE Table1
	([City] varchar(9), [Title] varchar(6), [Seller] varchar(25), [ActiveStatus] varchar(1))

	
INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES 	('Chennai', 'Book1', 'AAA','Y')

INSERT INTO Table1([City], [Title], [Seller],[ActiveStatus])
VALUES 	('Chennai', 'Book2', 'BBB','Y')

INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES ('Chennai', 'Book3', 'A1A','Y')

INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES ('Mumbai', 'Book1', 'SAS','Y')

INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES ('Mumbai', 'Book2', 'SAY','Y')

INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES ('Mumbai', 'Book3', 'MBM','Y')

INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES ('Bangalore', 'Book3','ADF','Y')

INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES ('Bangalore', 'Book2', 'ASD','Y')

INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES ('Bangalore', 'Book1', 'DWE','Y')

INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES ('London', 'Book2', 'LLA','Y')

INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES ('London', 'Book1', 'SLA','Y')

INSERT INTO Table1
	([City], [Title], [Seller],[ActiveStatus])
VALUES ('London', 'Book3', 'SSS','N')

I would like to have the following output

Chennai     [Book1: AAA]  [Book2:BBB]  [Book3: A1A]
 Mumbai     [Book1: SAS]  [Book2:SAY]  [Book3: MBM]
 Bangalore  [Book1: DWE]  [Book2:ASD]  [Book3: ADF]
 London      [Book1: SLA]  [Book2:LLA]  ]

I used the below query for achieving this output:

SELECT City, 
   '[Book1: ' + Book1 + '] ' + 
   '[Book2: ' + Book2 + '] ' + 
   '[Book3: ' + Book3 + '] ' AS BookDetails
FROM (
   SELECT City, 
      [Book1] as Book1,
      [Book2] as Book2,
      [Book3] as Book3
   FROM (SELECT City, Title, Seller FROM Table1 WHERE ActiveStatus='Y') t1
      PIVOT (MIN(Seller) FOR Title IN ([Book1], [Book2], [Book3])) as pvt
   ) a
ORDER BY City

Open in new window


i got the following output when i execute this query


Bangalore      [Book1: DWE] [Book2: ASD] [Book3: ADF]
Chennai           [Book1: AAA] [Book2: BBB] [Book3: A1A]
London          NULL
Mumbai          [Book1: SAS] [Book2: SAY] [Book3: MBM]

For the City London the activestatus for Book1 and Book2 is 'Y'
Then Why it is showing NULL ?  How do i show the Book1 and Book2 for London ?
