I’m working with a SQL view that I created but I want to add in an ID column (identity seed) as the current one has none. How can I accomplish this in SQL View?

I’m working with a SQL view that I created but I want to add in an ID column (identity seed) as the current one has none. How can I accomplish this in SQL View?
If there is no identity column in the underlying table, you can generate one with pseudo-columns.
In SQL server: SELECT ROW_NUMBER() OVER (ORDER BY FiscalYear, FiscalMonth), FiscalYear, FiscalMonth, … FROM …
See http://msdn.microsoft.com/en-us/library/ms186734.aspx
In Oracle: SELECT ROWNUM, FiscalYear, FiscalMonth, … FROM … .
In oracle, ROWNUM uses the order in the result set.
