I have two data sources:
Source 1 contains product id and price date, need to find the price that corresponds with the date from Source 2 based on product id and between two date ranges because there is no exact date match. Here are the tables:
Source 1
Product ID Price Date Need price
2512330 05/07/2016 ???
2512330 06/07/2016 ???
2512330 06/13/2016 ???
2512330 07/20/2016 ???
2512330 08/27/2016 ???
2512330 09/22/2016 ???
Source 2:
