Hello Experts,

I have two tables, Jobs & GoodsReceipts. In Jobs there is an ActionDate (datetime) column which I need to compare with GoodsReceipts column Date (datetime) and if they differ, update GoodsReceipts with the new date.

I am sure the answer is very simple but I am having one of them days :(

I'm using MS SQL SERVER 2008.

Thanks,


David

   WHERE r.GoodsREceips <> j.ActionDate
