Unmatched Records for Specific Product ID Query

Experts,

I am at a total loss! I cannot figure out the correct syntax for a query that is trying to find unmatched records.

I have the following tables:

tblProductPrice
PK: CostID
Lng: SiteID
Lng: TTechID


tblWebsite
PK: WebsiteID
Str: WebAddress

The query will have a particular TTechID that it needs to find any WebsiteID's that are not in the tblProductPrice.SiteID for that specific TTechID.

I've tried the following sql
SELECT tblWebsite.WebAddress
FROM tblWebsite
WHERE NOT EXISTS (SELECT SiteID FROM tblProductPrice WHERE tblProductPrice.SiteID = tblWebsite.WebsiteID)

Open in new window


and

 
SELECT tblWebsite.WebAddress
FROM tblWebsite LEFT JOIN tblProductPrice ON tblWebsite.WebsiteID = tblProductPrice.SiteID
WHERE (((tblProductPrice.SiteID) Is Null));

Open in new window


Neither of these work correctly specifically because they don't have any reference to the TTechID in question.

Please help me add whatever conditional statement is needed to refine the query search to the specific TTechID in question.

Thank you!

WHERE NOT EXISTS (SELECT SiteID FROM tblProductPrice WHERE tblProductPrice.SiteID = tblWebsite.WebsiteID
                                                           AND tblProductPrice.TTechID=1)

Open in new window

SELECT tblWebsite.WebAddress
FROM tblWebsite LEFT JOIN tblProductPrice ON (tblWebsite.WebsiteID = tblProductPrice.SiteID
                                             AND tblProductPrice.TTechID=1)
WHERE tblProductPrice.SiteID Is Null

Hi

Please find the query below
DECLARE @TTechID INT
SET @TTechID =1
SELECT 
	websiteId, 
	webaddress 
	FROM tblWebsite 
	WHERE WebsiteID not in 
		(
			SELECT siteid 
			FROM tblProductPrice 
			WHERE TTechID=@TTechID
		)

Open in new window
