Use PHP and MySQL. In my table, there is date field (datetime) recorded by NOW() sql function. Example val开发者_JS百科ue of data in this field is 2010-10-07 10:57:36. How can I SELECT all data which day-month-year is today. I try to use code as below:
SELECT * FROM table WHERE date=????
Try this:
SELECT * FROM table WHERE date > CURDATE();
CURDATE()
will return the current date as 2011-10-07
which will be cast to 2011-10-07 00:00:00
when comparing datetime
s to it.
Note that if you use DATE(date) = CURDATE()
you will run a date conversion for every row in the table, which will be really bad for your perfomance if you have many rows and/or you need to run the query often. Also make sure you have an index on date
, otherwise both methods will be even slower.
SELECT * FROM table where DATE(date)=CURDATE()
SELECT * FROM tableName WHERE DATE(fieldDate) = DATE(NOW());
The date_format
function allows you to easily switch between various granularities:
Select everything from the same day:
select * from table
where date_format(date, '%Y-%m-%d') = date_format(now(), '%Y-%m-%d');
From the same month:
select * from table
where date_format(date, '%Y-%m') = date_format(now(), '%Y-%m');
From the same year:
select * from table
where date_format(date, '%Y') = date_format(now(), '%Y');
From the same hour:
select * from table
where date_format(date, '%Y-%m-%d %H') = date_format(now(), '%Y-%m-%d %H');
and so on.
Try this
SELECT * FROM table WHERE DATE(my_date)=DATE(now())
my_date -> column name
SET @day = '2017-12-12' ;
SELECT * FROM table WHERE dateColumn BETWEEN DATE(@day) AND DATE_ADD(DATE(@day), INTERVAL 1 DAY ) ;
use something like this it exactly works on my code(access database):
select * from Table t where t.column>=Date() and t.column< Date() + 1
use between.
select * from table date between '2010-10-06' and '2010-10-08';
