UPDATE: The values seem to be Y and NULL. It isn't a boolean value after all, it is a varchar. Now I really don't understand why my query won't run.

I am trying to limit the records based on whether or not the payment has declined. This query does not throw an error but does nto pull any records even though I know there are records that don't have the paymentdeclined set to Y. The paymentdeclined is set as a boolean in the database. Can anyone please supply a second set of eyes and tell me what I am screwing up.

Thanks so much


SELECT OrderDate AS 'Order Date',
	    PaymentAmount AS 'Total Payments',
	    TotalShippingCost AS 'Shipping Received',
	    SalesTax1 AS 'Sales Tax Received',
	    PaymentDeclined AS ' Payment Declined'
FROM Orders
WHERE PaymentDeclined <> 'Y'
ORDER BY OrderDate DESC

SQL doesn't have boolean values, only values that the user can interpret as true or false.
Do SELECT DISTINCT PaymentDeclined FROM Orders, and see what the values are. That's what you'll have to use
in your query.

Probably becuase any value comapred to NULL equals UNKNOWN. Try this:
SELECT OrderDate AS 'Order Date',
	    PaymentAmount AS 'Total Payments',
	    TotalShippingCost AS 'Shipping Received',
	    SalesTax1 AS 'Sales Tax Received',
	    PaymentDeclined AS ' Payment Declined'
FROM Orders
WHERE PaymentDeclined IS NULL
ORDER BY OrderDate DESC

WHERE isnull(PaymentDeclined,'') <> 'Y'

No, you're never too old to Yak'n'Roll if you're too young to die.
