Equivalent of Oracle's RowID in SQL Server

Question

What\'s the equivalent of Oracle\'s RowID in SQL Server?

Answer 1

I have to dedupe a very big table with many columns and speed is important. Thus I use this method which works for any table:

delete T from 
(select Row_Number() Over(Partition By BINARY_CHECKSUM(*) order by %%physloc%% ) As RowNumber, * From MyTable) T
Where T.RowNumber > 1
