How to select records from last 24 hours using SQL?

Question

I am looking for a where clause that can be used to retrieve records for the last 24 hours?

Answer 1

In Oracle (For last 24 hours):

SELECT  *
FROM    my_table
WHERE   date_column >= SYSDATE - 24/24

In case, for any reason, you have rows with future dates, you can use between, like this:

SELECT  *
FROM    my_table
WHERE   date_column BETWEEN (SYSDATE - 24/24) AND SYSDATE
