Q:

Get specific date range

I'm using 
SELECT * from tbl_name WHERE DATE_SUB(CURRENT_DATE(), INTERVAL 3 DAY)

to select data for specific days. The problem is that line gets data right before 3 days. 
What to do so selected data to be period three days before till now ?

A:

First your field should be of type datetime or date and then you can use a between clause 
your_date_field BETWEEN now() - INTERVAL 72 HOURS AND now()
