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  *

WHERE   record_date >= (Now - 1)
