Get the values for last 6 months in mysql

Question

I need to get last six month values from the database. Here is my Fiddle. I need to get the values dynamically. Now February. So I need August to Januar

Answer 1

For MYSQL: you may use date_add:

 SELECT * FROM ratepersqft 
WHERE date < Now() and date > DATE_ADD(Now(), INTERVAL- 6 MONTH);

For SQL Server:, dateadd :

  SELECT * FROM ratepersqft 
 WHERE date < Now() and date > DATEADD(Month, -6, Now());

**Please wrap your date column name with backticks given it is a reserved key word. **

MYSQL update:

SQLFIDDLE DEMO

SELECT *
FROM ratepersqft 
WHERE date_format(date,'%Y-%m') < 
                     date_format(now(),'%Y-%m')
and date_format(date,'%Y-%m') >= 
                     date_format(now() - interval 6 month,'%Y-%m')
order by date desc;

Answer 2

SQLFiddle

If you want full months only

SELECT *
FROM ratepersqft
WHERE date between date_format(DATE_SUB(CURDATE(), INTERVAL 6 MONTH), '%Y-%m-01')
           and  date_sub(date_format(CURDATE(), '%Y-%m-01'), interval 1 day);

Answer 3

 SELECT
YEAR(DATE) AS YEAR,
SUM(MONTH(DATE) = 1) AS JAN ,
SUM(MONTH(DATE) = 2) AS FEB ,
SUM(MONTH(DATE) = 3) AS MAR ,
SUM(MONTH(DATE) = 4) AS APR,
SUM(MONTH(DATE) = 5) AS MAY ,
SUM(MONTH(DATE) = 6) AS JUNE ,
SUM(MONTH(DATE) = 7) AS JULY ,
SUM(MONTH(DATE) = 8) AS AUG,
SUM(MONTH(DATE) = 9) AS SEP ,
SUM(MONTH(DATE) = 10) AS OCTOBER ,
SUM(MONTH(DATE) = 11) AS NOV ,
SUM(MONTH(DATE) = 12) AS DECE
FROM ratepersqft
WHERE  DATE >= NOW() - INTERVAL 6 MONTH 
GROUP BY 1;

Answer 4

This will consider all dates to be rounded to the beginning of the month for comparisons, and will get last 6 months from today's date:

SELECT *
FROM ratepersqft
WHERE date >= DATE_SUB(DATE_FORMAT(CURDATE(), '%Y-%m-01'), INTERVAL 6 MONTH)
  AND date <  DATE_FORMAT(CURDATE(), '%Y-%m-01')

Obligatory SQLFiddle.
