To use the above Examples add SELECT at left and run the query.
Some time we have to collect last 7 or 15 days or X days (or month, year or week) data from MySQL table.
For example let us find out who are the new members joined in our forum in last week. One shop may be interested in knowing new products added in last one month. What are the books arrived in last one year. Here irrespective of the date values we want the records of last X days from today, or we can say that the records between today and last X days ( month , year or week) are required.
We will use the MySQL function CURDATE() to get the today's date.
To get the difference in today date and previous day or month we have to use the MySQL function DATE_SUB
DATE_SUB is a MySQL function which takes date expression, the interval and the constant to return the date value for further calculation.
Here are some sample queries on how to get the records as per requirements .
Last 10 days records
select * from dt_table where `date` >= DATE_SUB(CURDATE(), INTERVAL 10 DAY)
The above query will return last 10 days records. Note that this query will return all future dates also. To exclude future dates we have to modify the above command a little by using between query to get records. Here is the modified one.
SELECT * FROM dt_table WHERE `date` BETWEEN DATE_SUB( CURDATE( ) ,INTERVAL 10 DAY ) AND CURDATE( )
Present Month Records
Starting from 1st day of the current month till now.
SELECT * FROM `dt_table` WHERE date between DATE_FORMAT(CURDATE() ,'%Y-%m-01') AND CURDATE()
Present Year Records
Starting from 1st Jan of the current Year till now.
SELECT * FROM `dt_table` WHERE date between DATE_FORMAT(CURDATE() ,'%Y-01-01') AND CURDATE()
Last one month records
Let us try to get records added in last one month
select * from dt_table where `date` >= DATE_SUB(CURDATE(), INTERVAL 1 MONTH)
Here also future records will be returned so we can take care of that by using BETWEEN commands if required.
select * from dt_table where `date` >= DATE_SUB(CURDATE(), INTERVAL 1 YEAR)
Records of previous month of any year
SELECT * FROM dt_table WHERE MONTH( DATE ) = MONTH( DATE_SUB(CURDATE(),INTERVAL 1 MONTH ))
Records of previous month of of same year
SELECT * FROM dt_table WHERE MONTH( DATE ) = MONTH( DATE_SUB(CURDATE(),INTERVAL 1 MONTH ))
YEAR( DATE ) = YEAR( DATE_SUB(CURDATE( ),INTERVAL 1 MONTH ))
Note the difference between Last one month record and Previous month record
Records of two date ranges
We can collect records between a particular date ranges by using between command and DATE_SUB. Here are some queries to generate records between two date ranges.
select * from dt_table where `date` BETWEEN DATE_SUB( CURDATE( ) ,INTERVAL 3 MONTH ) AND DATE_SUB( CURDATE( ) ,INTERVAL 0 MONTH )
This query will return records between last three months. This query again we will modify to get the records between three moths and six months.
select * from dt_table where `date` BETWEEN DATE_SUB( CURDATE( ) ,INTERVAL 6 MONTH ) AND DATE_SUB( CURDATE( ) ,INTERVAL 3 MONTH )
Now let us change this to get records between 6 month and 12 month.
select * from dt_table where `date` BETWEEN DATE_SUB( CURDATE( ) ,INTERVAL 12 MONTH ) AND DATE_SUB( CURDATE( ) ,INTERVAL 6 MONTH )
With this you can understand how the records between a month range or a year range can be collected from a table. Note that the months ranges are calculated starting from current day. So if we are collecting records of last three months and we are in 15th day of 9th month then records of 15th day of 6th month we will get but the records of 14th day of 6th month will be returning on next query that is between 3 months and 6 months.
Our sample table dt_table_tm stores login date with time in a field along with one more column showing event_id.
All records of Last 5 Hours
SELECT * FROM `dt_table_tm` WHERE tm>=DATE_SUB(NOW(), INTERVAL 5 HOUR)
All records of Last 48 Hours
SELECT * FROM `dt_table_tm` WHERE tm>=DATE_SUB(NOW(), INTERVAL 48 HOUR)
All records of 15 hours 12 minutes
SELECT * FROM `dt_table_tm` WHERE tm>=DATE_SUB(NOW() , INTERVAL '15:12' HOUR_MINUTE)
In place of NOW() we can use specific date and time ( timestamp )
Note : While using date use the format YYYY-mm-dd ( YEAR - Month - date) and while using time use HH:MM:SS ( Hour : Minutes : Seconds )
SELECT * FROM `dt_table_tm` WHERE tm >= DATE_SUB( '2018-08-10 11:50:00', INTERVAL '2:18:33' HOUR_SECOND )
All logins between 9 and 10 hours ( from 9 and 10 both inclusive till it is not 11 )
SELECT * FROM `dt_table_tm` WHERE HOUR(tm) between 9 and 10
All logins betwee 9 and 10 for a perticular month and year
SELECT * FROM `dt_table_tm` WHERE HOUR(tm) between 9 and 10 and MONTH(tm)=08 and year(tm)=2018
SELECT * FROM `dt_table_tm` WHERE HOUR(tm) between 9 and 10 and date_format(tm,'%Y-%m')='2018-08'
All logins between 11 and 18 hours on a prticular day
SELECT * FROM `dt_table_tm` WHERE HOUR(tm) between 11 and 18 and date(tm)='2018-08-09'
All logins between two input times in hour : minutes : seconds on a perticular day
SELECT * FROM `dt_table_tm` WHERE date(tm)='2018-08-09' AND TIME(tm) BETWEEN TIME('9:00:00') AND TIME('10:15:00')
Counting logins at different hours in all days ( using GROUP BY )
SELECT hour(tm) , count(event_id) FROM `dt_table_tm` group by HOUR(tm)
Records of last working days of week
Now let us try a different requirement. How to get the records of the working days of the week so far ? If today is Thursday then records from Monday to Thursday should be returned.
Dynamic SQL dump query
To test above queries you need to have records of last 15 days or last 6 months ( or 12 Months ). Any dump created today will not work in future dates ( say after 8 months ) . So to use above query which involves last 15 days or last 12 months records, we have to generate dump file every day.
For the SQL with date and time , another table dt_table_tm is used and the dump file can be used .
I am trying to rum this query concatenated with my php tag cloud generation generation query... I want to fetch tags popular in the week ordered by views...
here is the querry ... and its not wroking...
SELECT tag, views, date FROM tags WHERE date BETWEEN DATE_SUB(CURDATE(), INTERVAL 7 DAY) AND CURDATE() GROUP BY tag ORDER BY date DESC, RAND() ASC LIMIT 0,20
SELECT count(views)as no,tag,date FROM tags WHERE date BETWEEN DATE_SUB(CURDATE(),INTERVAL 7 DAY) AND CURDATE() GROUP BY tag ORDER BY no DESC LIMIT 0,20
I am sorry this does'nt work are desired... actually views are for each tag and is an updating value... each time a tag page loads its value is updated by 1 which also determines the font size in tha php tag cloud... please help...
I am forced to use this query
SELECT tag, views, date FROM tags WHERE date >= DATE_SUB(CURDATE(), INTERVAL 7 DAY) GROUP BY tag ORDER BY date DESC, RAND() ASC LIMIT 0,20
SELECT * FROM $table WHERE disabled='0' AND featured='0' AND recommended='0' AND date BETWEEN DATE_SUB(CURDATE(), INTERVAL 3 DAY) AND CURDATE() ORDER BY comments DESC, views DESC
i got the answer for what i m searching.
I can't understand date >= DATE_SUB(CURDATE(), INTERVAL 7 DAY) gives me the twoo years ago
i have table which contain date from 1995-01-01 to current date and i want to select only one date in month is there any query in mysql for this problem
This doesnt seem to work for dates stored as a Unix Timestamp

For Example 7 days leave (LAP) from 01/01/2017 upto 01/07/2017 for XYZ designation JE. In SQL Server record insert LeaveApp table as XYZ, JE, Leave, LAP, 01/01/2017, 01/07/2017 in one line. But I want the record in another table like Attendance table as in row 1 => XYZ, JE, Leave, LAP, 01/01/2017, 01/01/2017
In row 2 => XYZ, JE, Leave, LAP, 01/02/2017, 01/02/2017 In row 3 => XYZ, JE, Leave, LAP, 01/03/2017, 01/03/2017 and so on upto Last row => XYZ, JE, Leave, LAP, 01/07/2017, 01/07/2017.
How to create code in vb.net 2008 or vb.net c# 2008.
Please Help me in this regards.
I have certain data stored in DB in milliseconds. But this was not the format I wanted so I converted it into actual date format. The format is getting updated as a new column during runtime. strftime(MillisField*1000,'%Y %m %d %H:%M:%s') as date.
This returns the actual date and time format in a new column.
But the problem here is if I want the last six months of some particular data, so I tried this:
MillisField > 2017-12-01
It didn't show me the last six months of data, but, if I try this:
MillisField > 1512066600000
it shows the exact result I wanted, but I want to give it in date rather than milliseconds
Add one more timestamp field to the table, then on a single query update this filed by converting MillsField to required format. Once you are satisfied with the new field and gets the data in desired format , delete the MillsField
if want to get the records between from the starting of this month date and the current date, then what will be the query/condition that time
To get first day of the month use DATE_FORMAT(CURDATE() ,'%Y-%m-01'). The complete query is added to the tutorial above.
