Diff - No Rows Vs 0 Rows

When Oracle will return 0 rows selected or no rows Selected while issuing a select query

Well run a query against an empty table a see for yourself..

Code:

---

appdev@NICK>select * from time_diff;

no rows selected

appdev@NICK>select count(*) from time_diff;

  COUNT(*)
----------
        0

---

Or did I get your Q wrong?
