The last thing we need to do is modify our XSLT filter to use the PDFWriter when html is the output format. The modified XSLTPDFFilter class is shown in listing 5.13.

USE tempdb; IF OBJECT_ID('dbo.OrderTotals', 'V') IS NOT NULL DROP VIEW dbo.OrderTotals; IF OBJECT_ID('dbo.OrderDetails', 'U') IS NOT NULL DROP TABLE dbo.OrderDetails; GO CREATE TABLE dbo.OrderDetails ( oid INT NOT NULL, pid INT NOT NULL, qty INT NOT NULL, PRIMARY KEY(oid, pid) ); INSERT INTO dbo.OrderDetails(oid, pid, qty) VALUES (10248, 1, 10), (10248, 2, 20), (10248, 3, 30), (10249, 1, 5), (10249, 2, 10), (10249, 3, 15), (10250, 1, 20), (10250, 2, 20), (10250, 3, 20); GO CREATE VIEW dbo.OrderTotals AS SELECT oid, SUM(qty) AS totalqty FROM dbo.OrderDetails GROUP BY oid; GO

ALTER TABLE Sales.Customers ADD PRIMARY KEY(custid); SELECT n AS orderid, DATEADD(day, ABS(CHECKSUM(NEWID())) % (4*365), '20060101') AS orderdate, 1 + ABS(CHECKSUM(NEWID())) % 10000 AS custid, 1 + ABS(CHECKSUM(NEWID())) % 40 AS empid, CAST('a' AS CHAR(200)) AS filler INTO Sales.Orders FROM dbo.Nums WHERE n <= 1000000; ALTER TABLE Sales.Orders ADD PRIMARY KEY(orderid); CREATE INDEX idx_cid_eid ON Sales.Orders(custid, empid);

The first exercise involves multiple references to the same intermediate result set of a query . The task is to query the Orders table, and return for each order year the number of orders placed that year, and the difference from the number of orders placed in the previous year . Here s the desired output when you run your solution against InsideTSQL2008:

import import import import import import import import import javax.servlet.*; javax.servlet.http.*; java.io.*; java.util.*; org.jdom.*; org.jdom.output.*; org.jdom.transform.*; javax.xml.transform.*; javax.xml.transform.stream.*;

orderyear ----------2006 2007 2008 numorders ----------152 408 270 diff ----------NULL 256 -138

You could use a table expression representing yearly counts of orders, and join two instances of the table expression to match to each current year the previous year, so that you can calculate the difference . Here s an example for implementing such an approach using a CTE:

SET STATISTICS IO ON; WITH YearlyCounts AS ( SELECT YEAR(orderdate) AS orderyear, COUNT(*) AS numorders FROM Sales.Orders GROUP BY YEAR(orderdate) ) SELECT C.orderyear, C.numorders, C.numorders - P.numorders AS diff FROM YearlyCounts AS C LEFT OUTER JOIN YearlyCounts AS P ON C.orderyear = P.orderyear + 1;

Remember that a table expression is nothing but a reflection of the underlying tables . When you query two occurrences of the YearlyCounts CTE, both get expanded behind the scenes . All the work of scanning the data and aggregating it happens twice . You can see this clearly in the query s execution plan shown in Figure 7-4 .

public class XSLTFilter implements Filter { private FilterConfig filterConfig;

FiguRe 7-4 Execution plan for a solution to the comparing periods exercise (using table expressions)

Scanning the base data from the clustered index involves 28,807 reads . Because the data was scanned twice, STATISTICS IO reports 57,614 reads . As you can realize, scanning and aggregating the base data twice is unnecessary . This is a scenario where you should consider using a temporary table or a table variable . When choosing between the two, remember that one of the things to consider is the size of the intermediate result set that will be stored in the temporary object . Because the intermediate result set here will have only one row per year, obviously it s going to be very tiny, and it will probably require only one or two pages . In this case, it makes sense to use a table variable and benefit from the fact that it will not cause plan optimality related recompiles . Here s the solution using a table variable:

DECLARE @YearlyCounts AS TABLE ( orderyear INT PRIMARY KEY, numorders INT ); INSERT INTO @YearlyCounts(orderyear, numorders) SELECT YEAR(orderdate) AS orderyear, COUNT(*) AS numorders FROM Sales.Orders GROUP BY YEAR(orderdate);
