Oracle/SQL: Why does query “SELECT * FROM records WHERE rownum >= 5 AND rownum <= 10” - return zero rows

Question

Why does the following query return \'zero\' records:

SELECT * FROM records WHERE rownum >= 5 AND rownum <= 10

     OR

SELECT * FROM records WHERE rownum >=          


        

Answer 1

Alternative is to use MINUS

SELECT * FROM records 
WHERE   ROWNUM <= 10
minus SELECT * FROM records 
WHERE   ROWNUM <= 5

this will filter out non-unique values so you better be selecting id.

Hope this saves you some time.
