Question

In MySQL I have this query

SELECT DISTINCT date, descr FROM book ORDER BY date

Date is in format yyyy-mm-dd

I want to select only the the books from January 2012. I have tried to use like but that does not work.

Any ideas?

Answer 1

Using DATE_FORMAT function

SELECT DISTINCT date, descr FROM book 
WHERE DATE_FORMAT(date, '%Y %m') = DATE_FORMAT('2012-01-01', '%Y %m')
ORDER BY date

Or using MONTH and YEAR functions

SELECT DISTINCT date, descr FROM book 
WHERE Month(date) = Month('2012-01-01')
AND Year(date) = Year('2012-01-01')
ORDER BY date;

Or using BETWEEN functions

SELECT DISTINCT date, descr FROM book 
WHERE date BETWEEN '2012-01-01'
AND '2012-01-31'
ORDER BY date;

Or using <= and >= operators

SELECT DISTINCT date, descr FROM book 
WHERE date >= '2012-01-01'
AND date <= '2012-01-31'
ORDER BY date;
