How can I get the number of second between NOW() and a date in the database.
Thanks.
Use the TIMESTAMPDIFF function. (the TIMEDIFF function has a upper limit of 838:59:59)
SELECT TIMESTAMPDIFF(SECOND, DateColumn, NOW()) As Seconds
FROM table
Try this:
SELECT TIME_TO_SEC(TIMEDIFF(Now(), yourDateTime)) From Table;
MySQL: Now()
MySQL: TimeDiff-Function
MySQL: TIME_TO_SEC-Function

Let say i have a date field and i want to calculate the days between
Selected date on the date field and now() as in system date how do i make the query using SQL?
select DATEDIFF(columnwithdatename, NOW()) from table
Use the DateDiff function:
http://dev.mysql.com/doc/refman/5.7/en/date-and-time-functions.html#function_datediff
e.g.
SELECT DATEDIFF(MyDateColumn, NOW()) FROM MyTable;
use the sql datediff function
for example
select datediff(day, myDate, getdate()) as daysAgo
from myTable
Maybe try using DATEDIFF SQL function (http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_datediff).
So for example:
SELECT DATEDIFF(NOW(), your_date_field) FROM your_table;
I am trying to query a MYSQL database to return all records with today's date -
SELECT *
FROM credit_application
created_on = '15-OCT-15';
But it's failing because of the 'OCT' part within the query. How can I resolve this please?
Use mysql DATE_FORMAT function
SELECT *
FROM credit_application
DATE_FORMAT(created_on,'%d-%b-%y') = '15-OCT-15';
Use mysql STR_TO_DATE function
SELECT *
FROM credit_application
created_on = STR_TO_DATE('15-OCT-15', '%d-%b-%y');
Of course, this assumes your created_on field is just a DATE. If it's actually a DATETIME or TIMESTAMP, then you'll need to do a range query instead:
SELECT *
FROM credit_application
created_on >= STR_TO_DATE('15-OCT-15', '%d-%b-%y') AND
created_on < DATE_ADD(STR_TO_DATE('15-OCT-15', '%d-%b-%y'), INTERVAL 1 DAY);
The other suggestions of using DATE_FORMAT would require the function to be applied to every row in the table, preventing use of any index you might have. It would be a non-sargable query.
I would like to SELECT 5 Items WHERE unix_timestamp is after today.
Example:
unix_timestamp (here not the format):
15.08.2013
18.08.2013
21.08.2013
27.08.2013
30.08.2013
MySQL: SELECT * WHERE unix_timestamp is today or after today and ORDER BY unix_timestamp with LIMIT 0,5
MySQL Result must be items with the unix_timestamp:
18.08.2013
21.08.2013
27.08.2013
30.08.2013
This should actually work (DEMO):
SELECT FROM_UNIXTIME(unix_timestamp, '%m.%d.%Y') as `Date` FROM dates WHERE FROM_UNIXTIME(unix_timestamp, '%m.%d.%Y') >= DATE_FORMAT(NOW(), '%m.%d.%Y') ORDER BY unix_timestamp Limit 5;
I've assumed that because you have named your column unix_timestamp, your date is actually stored in that format (eg. 1376825624).
Note, that I would consider to change the name of unix_timestamp because there is allready a function in MySQL called UNIX_TIMESTAMP().
You can try something like this :
SELECT * FROM FOO
WHERE UNIX_TIMESTAMP >= NOW() ORDER BY UNIX_TIMESTAMP Limit 5;
NOW() Return the current date and time
If the UNIX_TIMESTAMP column contains the data in date format as per the example then instead of NOW() you can use CURRENT_DATE().
i.e.
SELECT * FROM FOO
WHERE UNIX_TIMESTAMP >= CURRENT_DATE() ORDER BY UNIX_TIMESTAMP Limit 5;
CURRENT_DATE() Return the current date
Date and Time Functions
I need to compare dates in MySQL ignoring the time portion in a DateTime column. I have tried the following SQL.
SELECT * FROM order_table where order_date=date_format('2012-05-03', '%Y-%m-%d');
It doesn't retrieve any row even though there is a date 2012-05-03 10:16:46 in MySQL table. How can the time portion in the DateTime field be ignored while comparing dates in MySQL?
You could use the DATE function:
SELECT col1, col2, ..., coln
FROM order_table
WHERE date(order_date) = '2012-05-03'
But this is more efficient, if your table is large and you have an index on order date:
SELECT col1, col2, ..., coln
FROM order_table
WHERE order_date >= '2012-05-03'
AND order_date < '2012-05-04'
If you want to pass in a date then you can try something like this:
where YEAR(order_date)='2012' AND MONTH(order_date)='05' AND DAY(order_date)='03'
You can look at this for more functions.
#Mark has got the good approach but just be careful that you will always have to calculate and find next day in that case. If you want to avoid that and still ignore time you could do following:
WHERE order_date >= '2012-05-27 00:00:00' AND order_date <= '2012-05-27 23:59:59'
I hope this makes sense.
SELECT * FROM order_table WHERE date(order_date) = '2012-05-03';
Maybe, you can use function like date(). But in this case speed can be decreased, because index cannot be using. So, I recommend to use
SELECT * FROM order_table
WHERE order_date between('2012-05-03 0:0:0' and '2012-05-03 23:59:59')
This is bit old .... but a correct answer also is using the date_format at the column order_date like below:
SELECT * FROM order_table where date_format(order_date, '%Y-%m-%d')='2012-05-03';
one of the following could be used when comparing dates in MySQL:
DATEDIFF() Subtract two dates
TIMEDIFF() Subtract time
TIMESTAMPDIFF() Subtract an interval from a datetime expression
PERIOD_DIFF() Return the number of months between periods
for more on date functions MySQL documentation.
In my case i had , DATE_FORMAT and CONVERT_TZ
The only one worked for me is this
DATE_FORMAT(CONVERT_TZ(`order_item`.created, '+0:00', '+2:00'), '%d/%m/%Y %H:%i')
BETWEEN
('12/02/2018 01:42')
AND
('12/02/2018 10:51')
I am stuck with a problem in MySQL. I want to get the count of records between two date-time entries.
For example:
I have a column in my table named 'created' having the datetime data type.
I want to count records which were created date-time between "TODAY'S 4:30 AM" and "CURRENT DATE TIME".
I tried some of MySQL's functions but still no luck with it.
Can you please help me with this?
thanks.
May be with:
SELECT count(*) FROM `table`
where
created_at>='2011-03-17 06:42:10' and created_at<='2011-03-17 07:42:50';
or use between:
SELECT count(*) FROM `table`
where
created_at between '2011-03-17 06:42:10' and '2011-03-17 07:42:50';
You can change the datetime as per your need. May be use curdate() or now() to get the desired dates.
select * from yourtable where created < now() and created > '2011-04-25 04:00:00'
select * from yourtable
where created < now()
and created > concat(curdate(),' 4:30:00 AM')
for speed you can do this
WHERE date(created_at) ='2019-10-21'
