Question

I want to compare two tables with the same columns:

• product – Id, Name, Description
• Temp_Product – Id, Name, Description

Now update done by user will be saved into Temp_Product. When admin will see the details of that product I need to show the changes done by user. I want to compare both tables with a query and return columns that have changed from Product to Temp_Product.

Please suggest me better way to do this?

Select p.id,p.name as orgn,t.name as altn,p.descripion as orgd,t.description as altd
from product p
join tmp_product t
on t.id=p.id and (t.name<>p.name or t.description <> p.description)
