How to select only date from a DATETIME field in MySQL? - mysql

I have a table in the MySQL database that is set up with DATETIME. I need to SELECT in this table only by DATE and excluding the time.
How do I SELECT in this table by only date and bypassing the time, even if that specific column is set to DATETIME?
Example
Now it is: 2012-01-23 09:24:41
I need to do a SELECT only for this: 2012-01-23

SELECT DATE(ColumnName) FROM tablename;
More on MySQL DATE() function.

you can use date_format
select DATE_FORMAT(date,'%y-%m-%d') from tablename
for time zone
sql2 = "SELECT DATE_FORMAT(CONVERT_TZ(CURDATE(),'US/Central','Asia/Karachi'),'%Y-%m-%d');"

Try to use
for today:
SELECT * FROM `tbl_name` where DATE(column_name) = CURDATE()
for selected date:
SELECT * FROM `tbl_name` where DATE(column_name) = DATE('2016-01-14')

You can use select DATE(time) from appointment_details for date only
or
You can use select TIME(time) from appointment_details for time only

In MYSQL we have function called DATE_FORMAT(date,format).
In your case your select statement will become like this:-
SELECT DATE_FORMAT(dateTimeFieldName,"%a%m%Y") as dateFieldName FROM table_name

Please try this answer.
SELECT * FROM `Yourtable` WHERE date(`dateField`) = '2018-09-25'

Simply You can do
SELECT DATE(date_field) AS date_field FROM table_name

I tried doing a SELECT DATE(ColumnName), however this does not work for TIMESTAMP columns† because they are stored in UTC and the UTC date is used instead of converting to the local date. I needed to select rows that were on a specific date in my time zone, so combining my answer to this other question with Balaswamy Vaddeman's answer to this question, this is what I did:
If you are storing dates as DATETIME
Just do SELECT DATE(ColumnName)
If you are storing dates as TIMESTAMP
Load the time zone data into MySQL if you haven't done so already. For Windows servers see the previous link. For Linux, FreeBSD, Solaris, and OS X servers you would do:
mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql
Then format your query like this:
SELECT DATE(CONVERT_TZ(`ColumnName`, 'UTC', 'America/New_York'))
You can also put this in the WHERE part of the query like this (but note that indexes on that column will not work):
SELECT * FROM tableName
WHERE DATE(CONVERT_TZ(`ColumnName`, 'UTC', 'America/New_York')) >= '2015-02-04'
(Obviously substitute America/New_York for your local time zone.)
† The only exception to this is if your local time zone is GMT and you don't do daylight savings because your local time is the same as UTC.

Try
SELECT * FROM Profiles WHERE date(DateReg)=$date where $date is in yyyy-mm-dd
Alternatively
SELECT * FROM Profiles WHERE left(DateReg,10)=$date
Cheers

Yo can try this:
SELECT CURDATE();
If you check the following:
SELECT NOW(); SELECT DATE(NOW()); SELECT DATE_FORMAT(NOW(),'%Y-%m-%d');
You can see that it takes a long time.

Select * from table_name where date(datetime)

Use DATE_FORMAT
select DATE_FORMAT(date,'%d') from tablename =>Date only
example:
select DATE_FORMAT(`date_column`,'%d') from `database_name`.`table_name`;

you can use date_format
select DATE_FORMAT(date,'%y-%m-%d') from tablename
for time zone
sql2 = "SELECT DATE_FORMAT(CONVERT_TZ(CURDATE(),'US/Central','Asia/Karachi'),'%Y-%m-%d');"
You can use select DATE(time) from appointment_details for date only
or
You can use select TIME(time) from appointment_details for time only
if time column is on timestamp , you will get date value from that timestamp using this query
SELECT DATE(FROM_UNIXTIME(time)) from table

SELECT DATE_FORMAT(NOW() - INTERVAL FLOOR(RAND() * 14) DAY,'%Y-%m-%d');
This one can be used to get date in 'yyyy-mm-dd' format.

if time column is on timestamp , you will get date value from that timestamp using this query
SELECT DATE(FROM_UNIXTIME(time)) from table

In the interest of actually putting a working solution to this question:
SELECT ... WHERE `myDateColumn` >= DATE(DATE_FORMAT(NOW(),'%Y-%m-%d'));
Obviously, you could change the NOW() function to any date or variable you want.

I solve this in my VB app with a simple tiny function (one line). Code taken out of a production app. The function looks like this:
Public Function MySQLDateTimeVar(inDate As Date, inTime As String) As String
Return "'" & inDate.ToString(format:="yyyy'-'MM'-'dd") & " " & inTime & "'"
End Function
Usage:
Let's say I have DateTimePicker1 and DateTimePicker2 and the user must define a start date and an end date. No matter if the dates are the same. I need to query a DATETIME field using only the DATE. My query string is easily built like this:
Dim QueryString As String = "Select * From SOMETABLE Where SOMEDATETIMEFIELD BETWEEN " & MySQLDateTimeVar(DateTimePicker1.Value,"00:00:00") & " AND " & MySQLDateTimeVar(DateTimePicker2.Value,"23:59:59")
The function generates the correct MySQL DATETIME syntax for DATETIME fields in the query and the query returns all records on that DATE (or BETWEEN the DATES) correctly.

Extract only the month in a query CodeIgniter

I want to make a query where I get people birthday's in a current month, I have problems with MONTH() it does not work for me, the date format in the database is: 04/18/1990, and I want to compare if the month current date('m') is equal to the month of the database.
Any suggestions?
you can try this one
SELECT * FROM table_name where extract(month from BirthDate) = date("m");
where date("m") return current month and BirthDate is column name in which you have stored birthdate.
Try this
"select month(str_to_date(birthdate), '%Y/%m/%d')
from users
where month(str_to_date(birthdate), '%Y/%m/%d') = '$month'"
Here, i m assuming your delimeter is '/', Please set your delimeter according to your string date i.e 2013/05/04 or 2013,05,04 or 2013-05-04
could be you have some convertion issue try using
select month(str_to_date(my_col, '%m/%d/%Y'))
from my_table
where month(str_to_date(my_col, '%m/%d/%Y')) = month(now())

sql condition as date and db date format is in datetime

I am trying to pass the date as a where condition in select query.but in the database the field is in datetime format.I don't know how to pass the condition?
SELECT * FROM (`scl_students`) WHERE `std_added_on` = '2015-03-03'
i got it.
SELECT * FROM (`scl_students`) WHERE DATE(std_added_on) = '2015-03-06'
I guess the problem is that the std_added_on contains time portion which could be non-zero. In order to select all rows for a given date you would write:
SELECT *
FROM `scl_students`
WHERE `std_added_on` >= '2015-03-03'
AND `std_added_on` < '2015-03-03' + INTERVAL 1 DAY
This is better than DATE(`std_added_on`) = ... performance wise.
You convert datetime to date after u try to run query
Use that query as this.
SELECT * FROM (scl_students) WHERE std_added_on = ('2015-03-03');
The datetime format expects that you parse time value also.
Try doing the following code.
SELECT * FROM (scl_students) WHEREstd_added_on= '2015-03-03 00:00:00'
Above query will only if your std_added_on value stored in database is = 2015-03-03 00:00:00

How to filter a timestamp format using Mysql?

I just want to ask how can i filter a timestamp value in Mysql?
Let's say we have the following datetime as
1351128031
1351128045
1351128097
How can I create a date range using this format?
How can I perform this in a query?
Like this:
SELECT * FROM user
WHERE acct_created BETWEEN (datefrom) AND (dateto) -- my problem is I can't filter the timestamp
You want to use a mysql function called UNIX_TIMESTAMP http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_unix-timestamp
SELECT * FROM user
WHERE acct_created BETWEEN UNIX_TIMESTAMP('datefrom') AND UNIX_TIMESTAMP('dateto')
where datefrom and dateto are dates formated as string similar to '2012-01-01 00:00:00' in UTC
Here is the SQLFiddel Demo
Below is the MySQL Select Query :
select *,
UNIX_TIMESTAMP(`Timestamps`)
from Table1
where UNIX_TIMESTAMP(`Timestamps`) between 1351128040 and 1351128099

Find results in certain date range

I am trying to only grab records that fall in a certain date range. The problem is that the timestamp and the date are stored as a string in the same cell. I want to only grab rows with a date that falls betweed 2013-05-01 and 2013-05-03.
date (stored as string)
2013-05-01T23:19:44
2013-05-02T23:19:40
2013-05-06T23:19:46
2013-05-06T23:15:17
mysql
SELECT * FROM table WHERE date BETWEEN 2013-05-01 AND 2013-05-03
Try
SELECT *
FROM table1
WHERE STR_TO_DATE(`date`,'%Y-%m-%d') BETWEEN '2013-05-01' AND '2013-05-03'
SQLFiddle
As #FreshPrinceOfSO absolutely correctly noted no index will be used in that case
SELECT * FROM table1
WHERE STR_TO_DATE(SUBSTRING(`date`,1,10),'%d-%m-%Y')
BETWEEN '2013-05-01' AND '2013-05-03'
The string is almost valid syntax for a datetime. Thus, an alternative, if perhaps slower method is to replace the 'T' with a space and then cast it to a datetime.
SELECT * FROM table1 WHERE
CAST(REPLACE(`date`, 'T', ' ') AS DATETIME)
BETWEEN '2013-05-01' AND '2013-05-03';
SELECT * FROM table
WHERE date('yourdate') BETWEEN date('2013-05-01') AND date('2013-05-03')

How can I return results less than current date?

I want to return results from my table that have a date less than today's date. Here is my statement:
$today = date('Y-m-d');
SELECT * FROM events WHERE STR_TO_DATE('$today', '%Y-%m-%d') > wp_eventscalendar_main.eventStartDate
I can select events in the future without a problem but when I try to select events in the past I don't get any results. My column 'eventStartDate' is set as a Date. Is there some kind of special operator I should be using for this?
Thanks,
You probably need:
SELECT * FROM events WHERE CURDATE() > wp_eventscalendar_main.eventStartDate
MySQL tries to compare a String to a Date, which won't work reliably.
You can Use
select from table_name where date < curdate()
