Question

I have a query like this in MYSQL DB

SELECT date_format( doj, '%d/%m/%Y' ) AS week ,COUNT(user_id) FROm user_tb 
WHERE doj between '2012-01-01' AND '2012-01-31' group BY WEEK(doj)

Result

week    COUNT(user_id)
06/01/2012  3
17/01/2012  2
25/01/2012  3
29/01/2012  1

How can I name it like this

week    COUNT(user_id)
week1   3
week2   2
week3   3
week4   1

Answer 1

Use the same week() function that you have used it in your group statement.

SELECT CONCAT("week", WEEK(doj)) AS week, COUNT(user_id) 
FROM user_tb 
WHERE doj between '2012-01-01' AND '2012-01-31' 
GROUP BY WEEK(doj)
