Question

I am nearly finished with my first assignment but the last question has me stumped.

It asks:

Produce a faulty product report that displays the product returned on the 11/07/2010 due to Damaged Exterior

The expected output for this is:

FAULTY PRODUCT REPORT

————————————–

Product Name: Desk

Customer Name: Simon, Kernel

Reason: Damaged Exterior

(1 rows(s) affected)

—END OF REPORT—

I found out about SQL PRINT now I seem to nearly have it all down to a T:

DECLARE @ProductName varchar(30)
SET @ProductName =(SELECT MIN(Products.ProductName) FROM Products)

DECLARE @CustomerName varchar(75)
SET @CustomerName =(SELECT MIN(Customers.FirstName+', '+Customers.Surname) 
FROM Customers,CustomerReturns,Products
WHERE CustomerReturns.ReturnDate='2012/07/11'
AND Products.ProductID=CustomerReturns.ProductID
AND Customers.CustomerID=CustomerReturns.CustomerID)

DECLARE @Reason varchar(30)
SET @Reason =(SELECT MIN(CustomerReturns.Reason) 
FROM CustomerReturns,Products,Customers
WHERE CustomerReturns.Reason='Damaged Exterior')

PRINT 'FAULTY PRODUCT REPORT';
PRINT '';
PRINT '---------------------';
PRINT 'Product Name: '+@ProductName;
PRINT 'Customer Name: '+@CustomerName;
PRINT 'Reason: '+@Reason;
PRINT '';
PRINT '---END OF REPORT---';

And my output:

FAULTY PRODUCT REPORT

————————————–

Product Name: Desk

Customer Name: Simon, Kernel

Reason: Damaged Exterior

—END OF REPORT—

As you can see I am still missing the:

(1 rows(s) affected)

How would i make this appear without ofcourse cheating and just printing it? (because then it will stay thay way no matter how many results get returned)

EDIT:

I found doing this: SELECT @ProductName... produces the 1row(s) affected, is this correct?:

PRINT 'FAULTY PRODUCT REPORT';
PRINT '';
PRINT '---------------------';
PRINT 'Product Name: '+@ProductName;
PRINT 'Customer Name: '+@CustomerName;
PRINT 'Reason: '+@Reason;
SELECT @ProductName,@CustomerName,@Reason
PRINT '';
PRINT '---END OF REPORT---';

EIDT2:

Changed it to this:

DECLARE @PName varchar(35)
DECLARE @CName varchar(75)
DECLARE @RName varchar(75)
SELECT @PName=Products.ProductName,
 @CName=Customers.FirstName+', '+Customers.Surname ,
 @RName=CustomerReturns.Reason

FROM Products,Customers,CustomerReturns

WHERE CustomerReturns.ReturnDate='2012/09/28'
AND CustomerReturns.Reason='Damaged Exterior'
AND Products.ProductID=CustomerReturns.ProductID
AND Customers.CustomerID=CustomerReturns.CustomerID
PRINT @PName
PRINT @CName
PRINT @RName

but still not affected rows thingy

Any help is appreciated thank you

Answer 1

Take a look at using the @@ROWCOUNT function after your query. This function returns the number of rows affected by the last statement. Read more about it here.

Using your second edit above, you could do:

DECLARE @PName varchar(35) 
DECLARE @CName varchar(75) 
DECLARE @RName varchar(75)
DECLARE @rowCount int 
SELECT @PName=Products.ProductName, 
 @CName=Customers.FirstName+', '+Customers.Surname , 
 @RName=CustomerReturns.Reason 

FROM Products,Customers,CustomerReturns 

WHERE CustomerReturns.ReturnDate='2012/09/28' 
AND CustomerReturns.Reason='Damaged Exterior' 
AND Products.ProductID=CustomerReturns.ProductID 
AND Customers.CustomerID=CustomerReturns.CustomerID

SET @rowCount = @@ROWCOUNT

PRINT @PName 
PRINT @CName 
PRINT @RName 
--Use @rowCount in your report.

Note that you have to obtain the row count immediately after you execute the query. This way, no matter how many rows you get, you’ll have the right number – avoiding the “cheat” scenario you mentioned.

Hope this helps.
