mysql extract year from date format - mysql

I need a mysql query to extract the year from the following date format from a table in my database.
For eg :
subdateshow
----------------
01/17/2009
01/17/2009
01/17/2009
01/17/2009
01/17/2009
the following query didn't working
select YEAR ( subdateshow ) from table
The column type is varchar. Is there any way to solve this?

Since your subdateshow is a VARCHAR column instead of the proper DATE, TIMESTAMP or DATETIME column you have to convert the string to date before you can use YEAR on it:
SELECT YEAR(STR_TO_DATE(subdateshow, "%m/%d/%Y")) from table
See http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_str-to-date

SELECT EXTRACT(YEAR FROM subdateshow) FROM tbl_name;

You can try this:
SELECT EXTRACT(YEAR FROM field) FROM table WHERE id=1

This should work:
SELECT YEAR(STR_TO_DATE(subdateshow, '%m/%d/%Y')) FROM table;
eg:
SELECT YEAR(STR_TO_DATE('01/17/2009', '%m/%d/%Y')); /* shows "2009" */

try this code:
SELECT DATE_FORMAT(FROM_UNIXTIME(field), '%Y') FROM table

This should work if the date format is consistent:
select SUBSTRING_INDEX( subdateshow,"/",-1 ) from table

TRY:
SELECT EXTRACT(YEAR FROM (STR_TO_DATE(subdateshow, '%d/%m/%Y')));

try this code:
SELECT YEAR( str_to_date( subdateshow, '%m/%d/%Y' ) ) AS Mydate

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())

MYSQL - Date stored in different format dd-mm-yy - Cannot retrieve values

I have a table with the following values.
As you can see in the picture date is not stored in standard mysql date format.
It is stored in dd-mm-yy
I want to select the rows for which the invoicedate is before 20-09-2017, so it should contain row 13-09-17.
I tried the following query, but it doesn't anything.
SELECT *
FROM `invoices`
WHERE date_format(invoicedate,'%d-%m-%Y') < date_format(20-09-17,'%d-%m-%Y')
Use 2017 as the year in your date, and wrap the date in a apostrophes:
SELECT *
FROM `invoices`
WHERE date_format(invoicedate,'%d-%m-%Y') < date_format('20-09-2017','%d-%m-%Y');
In my side the result of date_format('20-09-2017','%d-%m-%Y') is null,this might the reason for you.
Try with below(it works fine in my side):
SELECT *
FROM `invoices`
WHERE invoicedate < STR_TO_DATE('20-09-2017', '%d-%m-%Y');
SELECT *
FROM `invoices`
WHERE strtotime(invoicedate) < strtotime(20-09-17)
SELECT *
FROM invoices
WHERE STR_TO_DATE( invoicedate, '%d-%m-%Y' ) < STR_TO_DATE( '20-09-2017', '%d-%m-%Y' )
LIMIT 0 , 30

SELECT range of date in Text field

Date
9/25/2015
9/26/2015
9/27/2015
9/28/2015
9/29/2015
9/30/2015
10/1/2015
10/2/2015
10/3/2015
10/4/2015
10/5/2015
Can anyone help me in MySQL. I would like to select only date from 9/28/2015 to 10/4/2015.
Please take note, this date is in Text field.
Thank you.
you can use STR_TO_DATE(yourdatefield, '%m/%d/%Y') to convert text to date and you can later use between clause to restrict output data.
Convert first your dates using CONVERT, then use BETWEEN in your WHERE clause.
Try this..
SELECT * FROM TableName
WHERE Date BETWEEN CONVERT(DATE,'9/28/2015') AND CONVERT(DATE,'10/4/2015')
You can try like this:
WHERE `Date` BETWEEN CAST('9/28/2015' AS DATE) AND CAST('10/4/2015' AS DATE)
or
WHERE STR_TO_DATE(`Date`, '%m/%d/%Y') BETWEEN STR_TO_DATE('9/28/2015', '%m/%d/%Y') AND STR_TO_DATE('10/4/2015', '%m/%d/%Y')
DEMO
Also try to avoid storing dates as Text. Instead use Date datatype to store dates.
Try this , in where clause used function str_to_date
SELECT `dateVal`,`id`
FROM `datecheck`
WHERE STR_TO_DATE(`dateVal`,'%m/%d/%Y') between STR_TO_DATE('9/28/2015',
'%m/%d/%Y') AND STR_TO_DATE('10/4/2015', '%m/%d/%Y')
I had the same type of issue but in my case the date stored also contains the time (also in a text field, for instance 2017-09-11 05:07:58 PM). This is for a wordpress site but I want to query the database directly, the date is in a meta_value.
To make this work I ended using a subbstring of the date, i am posting this in case it helps someone:
SELECT ID, display_name, user_email, meta_value FROM bfge_users, bfge_usermeta WHERE (bfge_users.ID = bfge_usermeta.user_id) AND meta_key ='user_login' AND CAST(SUBSTR(meta_value,1,POSITION(' ' IN meta_value)) AS DATE) between '2017-09-11' AND '2017-09-13';
use between, you can read more here:

MYSQL Date query syntax not properly formatted

Here is how my column looks like
deeday
"06/07/15"
"02/07/15"
"06/07/15"
"04/07/15"
"06/07/15"
The following query works well
SELECT * FROM Bango ORDER BY STR_TO_DATE( `deday` , '%y/%m/%d' )
What am I missing in the following query to make it work.
SELECT * FROM `Bango` WHERE STR_TO_DATE( `deday` , '%y/%m/%d' ) = DATE_FORMAT(NOW(),'%d/%m/%y')
Thanks
Your query can work as per below-
SELECT * FROM `Bango` WHERE STR_TO_DATE( `deday` , '%d/%m/%y' ) = curdate();
You can use as per below but it will kill the performance, so you can remove " from your field one time-
SELECT * FROM
`Bango`
WHERE STR_TO_DATE( replace(`deday`,'"','') , '%d/%m/%y' ) = curdate();
SQL LIKE Statement on a DateTime Type
If the column type is datetime the LIKE operator doesn't work without converting the value to a varchar string on the fly.

How to change the date format in sql queries

I have date and time format as
2011-12-31 05:12:23
And i need to change it as follows:
Monday # 2:23AM 21/11/2011
I am using this sql query:
SELECT * FROM cms_content order by ID DESC;
where i have the fields as follows in my table named cms_content:
id, idname, author, date, title, body
So how to do this so that i can get the desired result?
Try this:
SELECT DATE_FORMAT(`date`, '%W # %l:%i%p %d/%m/%Y') FROM cms_content

[edit : additional]
I noticed a difference between your sample and expected data output so here's a literal answer to your date format inquiry:
SELECT DATE_FORMAT( DATE_ADD('2011-12-31 05:12:23', INTERVAL '-40 2:49' DAY_MINUTE ) , '%W # %l:%i%p %d/%m/%Y' )
