How can I select all records from the last week ( starting from Monday last week) ?
I am trying to use
yearweek() in my sql query but i was only able to select this week records
Here is a way to do it. First we need to get the last week Monday from current date, so we can use the following technique
Below will always give the Monday of the current week
mysql> select date_sub(curdate(), interval weekday(curdate()) day) as d ; +------------+ | d | +------------+ | 2016-09-19 | +------------+
Now to get the Monday of the last week we can adjust the above as
mysql> select date_sub(date_sub(curdate(), interval weekday(curdate()) day), interval 7 day) as d ; +------------+ | d | +------------+ | 2016-09-12 | +------------+
And finally to retrieve the data we can do as
select * from your_table where date_column >= date_sub(date_sub(curdate(), interval weekday(curdate()) day), interval 7 day)
Best is to handle the date calculation i.e. last week Monday on application level and then pass the value to the query.
