tblContractHeader ON tblContractDetails.cdeDID = tblContractHeader.chDID AND
tblContractDetails.cdeDocType = tblContractHeader.chDocType

left outer join tblAssetRegister on tblContractHeader.chPropertyID=tblAssetRegister.asID
WHERE (@DateFrom IS NULL OR
tblContractHeader.chDocumentDateTime >= @DateFrom) AND (@DateTo IS NULL OR
tblContractHeader.chDocumentDateTime <= @DateTo)

AND tblContractHeader.chIsDelete=0 and tblAssetRegister.asDocType='PRE1' and tblAssetRegister.asID is null
ORDER BY tblContractHeader.chDocumentDateTime

End else if @PropertyID is not null
Begin
SELECT tblContractDetails.*,tblContractHeader.*,tblAssetRegister.*

Method 1: Get a resultset with common 'Furniture' and 'Machinery' and use that in a subquery to exclude those results.

SQL

SELECT Flat, Land FROM tblProperty
WHERE Furniture NOT IN 
(SELECT Furniture FROM tblProperty p
INNER JOIN tblSales s ON p.Furniture = s.Furniture AND p.Machinery = s.Machinery)

Method 2: Simply using NOT IN clause in the query.

SQL

SELECT Flat, Land FROM tblProperty
WHERE Machinery NOT IN (SELECT Machinery FROM tblSales)
AND Furniture NOT IN (SELECT Furniture FROM tblSales)

I think Method 2 will be slower if your tables contain huge records. That's because tblSales table is queried two times here. So the overall data involved in second query is high.
I would suggest you still check the query plan for both the queries and go with the best plan.

Hope this helps!
