I need to update a Table Temp_MyTools

using this criteria
Create Table TempMyUpdate(Select MAX(UploadDate) as UploadDate,SerialNumber, FROM Inventory_SerializedAssets Where LocationID in(1));
update Temp_MyTools mt
Join Temp_MyUpdate as mu on mu.serialnumber = mt.serialnumber
   set mt.FUploadTime = mu.UploadDate


if there is nothing to update then Insert

/////insert
INSERT INTO Temp_MyTools(Select ToolType,SerialNumber,MAX(UploadDate) as FUploadTime, Cast('2012:01:01 12:00:00 AM'as DateTime) AS 'HUploadTime',  LocationID as DefaultLocationIndex, 1 as Qty FROM Inventory_SerializedAssets Where LocationID in(1) GROUP BY SerialNumber);

the tricky part is that this is part of a large query so it is not just by itself how would I do this?
