I have 2 different data-sets that I have imported from excel. There are 2 columns in the data-sets namely 'owner' and 'account'. I need to run a query to to compare how many additional 'accounts' do all the owners have compared to the first data-set.
Name of the first set is AMRS_May19 and for the second is AMRS_Apr19. so basically I am comparing the data between 2 months and checking how many additional accounts did the owner get tagged to, I need to run this query for all owners and for one specific owner if required.
Really appreciate the help.
