Generate an excel like report from SQL - sql-server

Question

I am novice to SQL and
I have two tables Ticket and TicketAttributes with following Schema
CREATE TABLE [dbo].[Ticket](
[TicketID] [int] IDENTITY(1,1) NOT NULL, --Primary key
[Category] [varchar](256) NOT NULL,
[Description] [varchar](256) NULL,
[LibID] [int] NOT NULL,
[Status] [smallint] NULL,
[LogID] [int] NULL)
Ticket Attributes
CREATE TABLE [dbo].[TicketAttributes](
[TicketID] [int] NOT NULL,
[TicketAttrID] [int] IDENTITY(1,1) NOT NULL,
[AttributeID] [int] NOT NULL,
[AttributeGroup] [varchar](255) NULL,
[AttributeValue] [nvarchar](max) NULL,
[Status] [smallint] NULL,
[LogID] [int] NULL)
Where Ticket Attribute is another table that stores different attributes of a ticket like TicketStatus, TicketCategory etc..
Now I need to generate a report that looks like
TicketStatus1 TicketStatus 2 TicketStatus3
-----------------------------------------------------------------
TicketCategory1 7 3
Ticketcategory2 4
TicketCategory3 8
I want to see the count of each of the status of each ticket category.
For Eg:-
I have the following Data in TicketTable
----------------------------------------------
TicketID Name Price Date
------------------------------------------------
155 Ticket4 $20 16 Jan 2016
157 Ticket3 $300 17 Jan 2016
158 Ticket1 $100 18 Jan 2016
159 Ticket2 $500 19 Jan 2016
Now in the TicketAttribute Table
----------------------------------------------
TicketID AttributeID AttributeValue
------------------------------------------------
155 500 Joe
155 600 Reserved
155 700 Economy
155 800 San Jose
where AttributeIDs
500=Nameofthe Passenger
600= Status of Ticket
700= Class
800= Destination
Now lets say I want to see what is the count of number of active tickets in each of the class per status
Booked Cancelled PaymentPending ............
-----------------------------------------------------------------
Economy 7 3
Economy Plus 4
Business 8
Hope I am clear now.
how to go about this using SQL Query

Answer 1

USING PIVOT
;WITH cte AS (
SELECT
c.AttributeValue as Class
,s.AttributeValue as StatusOfTicket
FROM
Ticket t
LEFT JOIN TicketAttributes c
ON t.TicketId = c.TicketId
AND c.AttributeID = 700
LEFT JOIN TicketAttributes s
ON t.TicketId = s.TicketId
AND s.AttributeID = 600
)
SELECT *
FROM
cte
PIVOT (
COUNT(StatusOfTicket) FOR StatusOfTicket IN (Reserved,Cancelled,PaymentPending)
) p
USING Conditional Aggregation:
SELECT
c.AttributeValue as Class
,COUNT(DISTINCT CASE WHEN s.AttributeValue = 'Reserved' THEN c.TicketId END) as Reserved
,COUNT(DISTINCT CASE WHEN s.AttributeValue = 'Cancelled' THEN c.TicketId END) as Cancelled
,COUNT(DISTINCT CASE WHEN s.AttributeValue = 'PaymentPending' THEN c.TicketId END) as PaymentPending
FROM
Ticket t
LEFT JOIN TicketAttributes c
ON t.TicketId = c.TicketId
AND c.AttributeID = 700
LEFT JOIN TicketAttributes s
ON t.TicketId = s.TicketId
AND s.AttributeID = 600
GROUP BY
c.AttributeValue
