    How to cross checking data from two different data source.

    Zyz Iwi

      Here is the problem I am facing:

       

      I got two data source, both containing IDs, say 4,000,000 IDs in data source A, and 1,000,000 IDs in data source B.

      How can i find out how many are cross overs, in other word, how many IDs in B also appears in A, vice versa.

       

      Thanks a lot!
