I have two tables of information on employees that are not related because they come from two different sources. I need to find which employees are not on both tables. I will need to also show which ones are on both tables. Thanks.
Sorry, I tried perhaps I am missing a step? I am using the Soc # on both tables as the related field. When I tried your suggestion I ended up with 23 Million records. The original tables had 1100 and 2100.
I did the left and right join queries then used those the two in order to create a third. What do you mean by "union select"? Maybe that is what I am missing?
