Determine Outflow by comparing counts on different days

[#1]

I have a table that has 2 fields:  Account Number and Date Completed.  I want to check if an Account Number on a given date exists on the following date.  If it exists, I can flag it as NOT complete.  If it does not exist, I can flag it as complete.  Can anyone help me with the code that I can put in the load script that would allow me to do this?  In the example below, the account 12340 on 1/5/15 would be flagged as 'complete' because it doesn't exist in the next existing date, which is 1/8/15.

Account Number	Date Completed
12345	1/5/15
12340	1/5/15
12380	1/5/15
12345	1/8/15
12380	1/8/15
12395	1/8/15

Thanks!
