MYSQL-如何在日期范围内查找记录

Question

The table I'm looking at has columns with fixed dates - EnteredDateTime and AuditDateTime . I need some help finding records that are older than 1 day and less than 7 days old

The code I'm using at the moment is -

EnteredDateTime BETWEEN DATE_ADD(AuditDateTime, INTERVAL 1 day) AND DATE_ADD(AuditDateTime, INTERVAL 7 day)

Answer 1

And what is the problem with your current query? Do you want older than 1 day and less than 7 days from today's date? If so, use DATE_SUB and NOW() :

EnteredDateTime BETWEEN DATE_SUB(NOW(), INTERVAL 1 day)
                    AND DATE_SUB(NOW(), INTERVAL 7 day)

Or if one of the columns answer this condition?

EnteredDateTime BETWEEN DATE_SUB(NOW(), INTERVAL 1 day)
                    AND DATE_SUB(NOW(), INTERVAL 7 day)
OR  AuditDateTime BETWEEN DATE_SUB(NOW(), INTERVAL 1 day)
                      AND DATE_SUB(NOW(), INTERVAL 7 day)

You can use GREATEST() or LEAST() if you know which one of the dates you want to check against (lowest or highest) to avoid the use of OR .
