Now i want to modify the column of Birthdate into 1990-10-11
i dont want rest of character .. guide me how to achieve this
Actually, I don't think you can change how MySql store is date type.
Here's a good article about it
MySQL stores dates and timestamps in one format only: YYYY-MM-DD
hh:mm:ss. This is the format recommended by the International
Organization for Standardization (ISO).
Instead what you can do is when you do a select statement is to format the date using Date_Format
SELECT DATE_FORMAT(birthDate, '%Y %m, %d') AS reg_formatted FROM yourtable
On the previous link you have all the formats possible

In my table, there is a date column i.e. ORDER DATE which is in dd-mm-yyyy format, and the datatype of this date column is text. Now, I want to convert the format from yyyy-mm-dd. But the date format is not changing at all. Trying to use STR_TO_DATE but the year in the dates are coming as 2020 only. Not sure how to fix it or if there is a better way to convert the date in MySQL.
For example:
SELECT STR_TO_DATE('14-09-2017','%d-%m-%y') AS DATE;
Result coming as 2020-09-14
Or suppose
SELECT STR_TO_DATE('20-MAR-2018','%d-%b-%y') AS DATE;
Result coming as 2020-03-20
day and month are coming properly but the year is not coming. Kindly help how to get convert the date format correctly.
Try to change your command like this below and you will get the answer:
SELECT STR_TO_DATE('14-09-2017','%d-%m-%Y') AS DATE;
Refer to the documentation for more info about the commands.
I am trying to convert long date format string (e.g. 1st-June-1999 or 20th-March-2001) to date YYYY-MM-DD using MySql 5.7.
Reading docs tried to use STR_TO_DATE:
select STR_TO_DATE(dob,'%d-%M-YYYY') from table
However, this returns null due to the day suffix (e.g. th).
I could use update query with REPLACE() to remove the suffix and then STR_TO_DATE, but is there a better solution?
You have two problems. First, you need %D (capital not lowercase) since you have the suffix after the day of the month.
Next, the year should simply be %Y.
So, the select statement would be
select STR_TO_DATE(dob,'%D-%M-%Y') from table;
w3schools has a good reference for the abbreviations: https://www.w3schools.com/sql/func_mysql_str_to_date.asp
%D does what you want:
str_to_date(dob, '%D-%M-%Y')
My current date formats are 01/01/2013 .... DD/MM/YYYY
How can I convert them all into MYSQL dates? I'm under The impression they are in the format YYYY-MM-DD
I don't know where to start.
my problem is that the dates are being ordered in the american way whilst they are in british format :(
Use the following query.
update tbl_name set your_field_name= str_to_date(your_field_name, '%d/%m/%Y');
It will update the value of your date from DD/MM/YYYY to YYYY/MM/DD.
Then you can change your filed type to date.
You can extract each part in php and concat the dd, mm, yyyy and save it to the DB
Why not DATE_FORMAT
DATE_FORMAT(date,'%Y-%m-%d')
How to convert date in MYSQL to correct format:
SELECT DATE_FORMAT(column_name, '%d/%m/%Y') FROM tablename
or
SELECT t.id, DATEDIFF(STR_TO_DATE(t.carddate, '%m/%d/%Y'), CURDATE)
FROM TABLE t

I have a very similar situation. I converted American date format "%Y-%d-%m" to correct format '%Y-%m-%d'. This is how I did it...
update table_name set my_date = DATE_FORMAT( STR_TO_DATE( my_date, '%Y-%d-%m' ) , '%Y-%m-%d' );
The first date string format '%Y-%d-%m' needs to be how the date is currently formatted in your table. The second date string is what you want to convert it to.
I have stored the dates as string in my database.I know it is not good,but project already has been half developed before i take over and where dates were stored as string,so i was continuing the same way.
Now i want to select dates from table where date is greater than a specific date.
I tried the following query
SELECT
*
FROM
dates
where
STR_TO_DATE(date, '%Y-%m-%d') > "2014-01-01"
but it is not returning only greater values.
Please help me to solve problem.

Your dates are not in YYYY-MM-DD format. Use the right format!
SELECT *
FROM dates
where STR_TO_DATE(date, '%m-%d-%Y') > date('2014-01-01')
If you are going to store dates as strings, then the best way is in the ISO format of YYYY-MM-DD.
You should read the documentation on str_to_date() (here).
Convert everything to date and it should be fine. Now you are comparing date and string.
What type has the date? I'd prefer a ' instead of " for strings in SQL. Let's assume that date is a VARCHAR or TEXT field (depending on which database you are using):
SELECT *
FROM dates
WHERE STR_TO_DATE(date, '%Y-%m-%d') > STR_TO_DATE('2014-01-01', '%Y-%m-%d')
If date is a real DATE
SELECT *
FROM dates
WHERE trim(date) > STR_TO_DATE('2014-01-01', '%Y-%m-%d')
Or you just convert it into a number format date_format(date,'%Y%m%d') > 20140101
I am trying to store the date in mysql as mm-dd-yyyy.
The following query updates the table stores the date as 0000-00-00
UPDATE `h3`.`newbatch` SET `DateCreated` = '11-08-2013' WHERE
`newbatch`.`BatchID` =
1 AND `newbatch`.`DateCreated` = '2013-11-08' LIMIT 1
I can always use DATE_FORMAT(DateCreated,'%m %d %Y') during select but is there a way to store date in that format.
The datatype of DateCreated is Date.
I am using MySQL.
Thanks
Do not modify the storage format of a date. The format for the date data type is ISO 8601 standard for a reason. You will lose the ability to perform most date functions elegantly (without first converting to the standard date format). You do the formatting when you run a query.
