I have to Update 3 fields in the Nop_ProductVariant table
with the values from the "ProdOne" table, based on the SKU field which is nvarchar(100).
Being the SKU is not an "int" field, what it the best way to do the join?

UPDATE Nop_ProductVariant
SET   OldPrice =   , ProductCost =  , Downloads =  

INNER JOIN ??
WHERE ???      SKU =

SELECT SRP, Cost, DL
FROM ProdOne

I'm assuming SKU is in both the Nop_ProductVariant and ProdOne tables....so you could try this...

DECLARE @OldPrice varchar(30)
DECLARE @ProductCost varchar(30)
DECLARE @Downloads int
DECLARE @SKU int
DECLARE @dynSQL nvarchar(1024)

SET @SKU = 1234
SELECT @OldPrice = SRP FROM ProdOne WHERE SKU = @SKU
SELECT @ProductCost = Cost FROM ProdOne WHERE SKU = @SKU
SELECT @Downloads =  DL FROM ProdOne WHERE SKU = @SKU

SET @dynSQL = 'UPDATE Nop_ProductVariant SET OldPrice = ' + @OldPrice + ', '+
	'ProductCost = ' + @ProductCost + ', Downloads = ' + CAST(@Downloads AS varchar) +
	' WHERE SKU = ' + CAST(@SKU AS varchar)

--PRINT @dynSQL
EXEC sp_executesql @dynSQL
