Unanswered: How does addition of two datetime data types work ?
SQL Server allows addition of two "datetime" values. For example let d1='April 10,2004' and d2='April 11, 2004'. Now when I execute d1+d2 I get 2108-07-20 00:00:00.000. On what logic is this calculation done.
I am actually looking to derive the same result in Oracle. Hence wanting to know the funda behind this.
