如何在Mysql中生成每月和每周报告？

Question

I want to display the data on a monthly and weekly basis, I already searched lot of stuff about this but what i found doesn't answer my question. Here is what my table looks like:

---------------
+ tblcomplain +
---------------
+ id          +
+ status      +
+ complain    +
+ dateposted  +
---------------

Answer 1

if your column is dateposted is of type timestamp/datetime:

For Weekly Report:

select count(*) as totalWeeklycomplaints from tblcomplain group by week(dateposted);

For Monthly Report:

select count(*) as totalMothlycomplaints from tblcomplain group by month(dateposted);

Answer 2

For weekly basis

SELECT 
    *, EXTRACT(WEEK FROM add_date) AS w1
FROM
    product_alert_stock
ORDER BY w1 , add_date ASC

For Monthly basis

SELECT 
    *, EXTRACT(Month FROM add_date) AS m1
FROM
    product_alert_stock
ORDER BY m1 , add_date ASC
