between date and greater than date in Oracle SQL

Question

Below is the data set and sysdate - 3rd Oct

ITEM    Date_from   Date_to
1234    1/1/2018    9/1/2018
1234    1/1/2018    10/1/2018
1234    1/1/2018    10/4/2018
1234    1/1/2019    12/31/2019

MY query:

select * from test_date where effect_to >= sysdate 
  minus
  select * from test_date where effect_to < sysdate ;

Correct Result:

1234    1/1/2018    10/4/2018
1234    1/1/2019    12/31/2019

Any better query ?

need to item dates which are currently effective and also effective for future dates.

Answer 1

I think you just want:

where effect_to > sysdate

or perhaps:

where effect_to >= trunc(sysdate)

depending on whether the last date is inclusive or exclusive.
