I have a database with about 100 tables. Many of the tables have common column names, such as EmployeeId, EmployeeRank, EmployeeAlternateId etc. So what I need to find out is which column name is the most common amongst all of the tables. Really what I need to do is to find out what the two most common column names in the database are. Does anyone know how I can do that? Is there a query which would give me the answer?
