Question

If I need to select database for the past month is this the correct way?

$month1=mysql_query("select * from users where date_sub(concat(curdate(), ' 00:00:00'), interval 1 month day(curdate()) day) < start and start < date_sub(concat(curdate(), ' 00:00:00'), interval day(curdate()) day)");

Is this field correct in particular: date_sub(concat(curdate(), ' 00:00:00'), interval 1 month day(curdate()) day)

Is there any best short alternative to simply select a table of JUST the previous month from the DB?

Answer 1

SELECT * FROM users 
   WHERE YEAR(`start`) = YEAR(DATE_SUB(NOW(), INTERVAL 1 MONTH)) 
      AND MONTH(`start`) = MONTH(DATE_SUB(NOW(), INTERVAL 1 MONTH))

EDIT: correction for the year condition.
