How to compare two DATE values based only on date part in Oracle?

Question

I am trying to get counts for last 30 days with the following query -

SELECT date_occured, COUNT(*) FROM problem
WHERE date_occured >= (CURRENT_DATE - 30)
GRO         


        

Answer 1

I think you'll want to trunc in the select part too:

 SELECT TRUNC(date_occured) AS short_date_occured, COUNT(*)
 FROM problem 
 WHERE date_occured >= trunc(SYSDATE- 30) 
 GROUP BY short_date_occured;
