Having spent my fair share of time mucking around with … well, time…I can tell you that I’d prefer to let someone else do the work for me. To that end, if you’re will to give it a go, I’d take a look at JodaTime Basically, what this example does it creates a series of … Read more
You don’t need to apply to_date() to sysdate. It is already there: select 1 from dual WHERE sysdate BETWEEN TO_DATE(’28/02/2014′, ‘DD/MM/YYYY’) AND TO_DATE(’20/06/2014′, ‘DD/MM/YYYY’); If you are concerned about the time component on the date, then use trunc(): select 1 from dual WHERE trunc(sysdate) BETWEEN TO_DATE(’28/02/2014′, ‘DD/MM/YYYY’) AND TO_DATE(’20/06/2014′, ‘DD/MM/YYYY’);
This is not possible without a recursive common table expression, which was introduced in SQLite 3.8.3: WITH RECURSIVE dates(date) AS ( VALUES(‘2015-10-03’) UNION ALL SELECT date(date, ‘+1 day’) FROM dates WHERE date < ‘2015-11-01’ ) SELECT date FROM dates;
I agree with Lieven’s answer create a table containing all the months you could ever require, and use that to “LEFT JOIN” to your results table. Remember, this is a really tiny table, only 365(ish) rows per year of data you have… And you can easily write some code to populate this table initially We … Read more
You can do either… $qb->where(‘e.fecha BETWEEN :monday AND :sunday’) ->setParameter(‘monday’, $monday->format(‘Y-m-d’)) ->setParameter(‘sunday’, $sunday->format(‘Y-m-d’)); or… $qb->where(‘e.fecha > :monday’) ->andWhere(‘e.fecha < :sunday’) ->setParameter(‘monday’, $monday->format(‘Y-m-d’)) ->setParameter(‘sunday’, $sunday->format(‘Y-m-d’));
The BETWEEN operator is inclusive. From Books Online: BETWEEN returns TRUE if the value of test_expression is greater than or equal to the value of begin_expression and less than or equal to the value of end_expression. DateTime Caveat NB: With DateTimes you have to be careful; if only a date is given the value is … Read more
From the MySQL-manual: This is equivalent to the expression (min <= expr AND expr <= max)
They are identical: BETWEEN is a shorthand for the longer syntax in the question that includes both values (EventDate >= ’10/15/2009′ and EventDate <= ’10/19/2009′). Use an alternative longer syntax where BETWEEN doesn’t work because one or both of the values should not be included e.g. Select EventId,EventName from EventMaster where EventDate >= ’10/15/2009′ and … Read more
You can use a concept that is frequently referred to as ‘calendar tables’. Here is a good guide on how to create calendar tables in MySql: — create some infrastructure CREATE TABLE ints (i INTEGER); INSERT INTO ints VALUES (0), (1), (2), (3), (4), (5), (6), (7), (8), (9); — only works for 100 days, … Read more
This solution uses no loops, procedures, or temp tables. The subquery generates dates for the last 10,000 days, and could be extended to go as far back or forward as you wish. select a.Date from ( select curdate() – INTERVAL (a.a + (10 * b.a) + (100 * c.a) + (1000 * d.a) ) DAY … Read more
