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

Answer 2

in postgres, assuming your field type is a timestamp:

select * from table where date_field > (now() - interval '24 hour');

Answer 3

Hello i now it past a lot of time from the original post but i got a similar problem and i want to share.

I got a datetime field with this format YYYY-MM-DD hh:mm:ss, and i want to access a whole day, so here is my solution.

The function DATE(), in MySQL: Extract the date part of a date or datetime expression.

SELECT * FROM `your_table` WHERE DATE(`your_datatime_field`)='2017-10-09'

with this i get all the row register in this day.

I hope its help anyone.

In MySQL:

SELECT  *
FROM    mytable
WHERE   record_date >= NOW() - INTERVAL 1 DAY

In SQL Server:

SELECT  *
FROM    mytable
WHERE   record_date >= DATEADD(day, -1, GETDATE())

In Oracle:

SELECT  *
FROM    mytable
WHERE   record_date >= SYSDATE - 1

In PostgreSQL:

SELECT  *
FROM    mytable
WHERE   record_date >= NOW() - '1 day'::INTERVAL

In Redshift:

SELECT  *
FROM    mytable
WHERE   record_date >= GETDATE() - '1 day'::INTERVAL

In SQLite:

SELECT  *
FROM    mytable
WHERE   record_date >= datetime('now','-1 day')

In MS Access:

SELECT  *
FROM    mytable
WHERE   record_date >= (Now - 1)

Answer 5

Which SQL was not specified, SQL 2005 / 2008

SELECT yourfields from yourTable WHERE yourfieldWithDate > dateadd(dd,-1,getdate())

If you are on the 2008 increased accuracy date types, then use the new sysdatetime() function instead, equally if using UTC times internally swap to the UTC calls.
