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.

In my table have two columns, one as timestamp to save the date and one as time string to save the time with period.
Eg:
I want to combine them into one column as DateTime format in the result then order by desc on that column.
Here is the example: http://sqlfiddle.com/#!9/25eb21/4
The column name 'Datetime' expected is Datetime or timestamps type, so I can sort correctly on it.
You do not need to convert the values to integers to add them. MySQL has built-in functions for this purpose:
SELECT *,
addtime(apptDate, str_to_date(apptTime, '%h:%i %p')) as datetime
FROM appt
ORDER BY Datetime DESC;
If apptTime is just a time value (which it should be), then you obviously do not need to convert from a string. I would usuggest fixing the data model.
Let me assume that you want to add the duration that is stored as a string in column apptTime to timestamp in column apptDate.
A typical approach uses str_to_date() to turn the string to a datetime, then converts the time portion to seconds using time_to_sec(), which we can then add to the timestamp using date artihmetics.
So
select t.*
apptdate
+ interval time_to_sec(str_to_date(appttime, '%h:%i %p')) second
as newapptdate
from mytable
select addtime(appDate, appTime) from ...
Your appDate contains a time, probably because you are applying a timezone. Either convert your two columns to the timezone your data is supposed to be in with convert_tz(), or extract the date part of it with date(appDate) before you add it. It wasn't clear which of the columns was a string, but extract() or str_to_date() is the way to parse a text into a date and/or time.
I want to fetch all datas that corresponds in the chosen date range.
So the problem is that. When theres included time in the data. It can't fetch the required data to be displayed. But when I remove the time on it. It displays really well. What can I do to make it right?
EXAMPLE VALUES:
2018-10-29 01:21:29pm
2018-10-30 01:21:29pm
EXAMPLE VALUES THAT WORKS:
2018-10-29
2018-10-30
My query:
`"SELECT *,SUBSTRING(order_date,1,10) from orders where order_date >='$fromdate' AND order_date <='$todate'"`
Ideal Solution: You will need to change the datatype of order_date from Varchar(500) to Datetime type, using Alter Table command.
Now, it is noteworthy that the MySQL datetime value is in YYYY-MM-DD HH:MM:SS format. So firstly, you will need to change your datetime string to MySQL datetime format string. Otherwise, directly changing the datatype will lead to irreparable loss/truncation of data.
Your datetime value 2018-10-29 01:21:29pm is basically of YYYY-MM-DD HH:MM:SS AM/PM (12 hour format). In terms of format specifiers, it would be: '%Y-%m-%d %h:%i:%s%p'. Complete list of available format specifiers can be seen in MySQL docs.
Firstly, we use Str_To_Date() function to convert all your data into proper Datetime format.
UPDATE orders
SET order_date = STR_TO_DATE(order_date, '%Y-%m-%d %h:%i:%s%p');
Now, next step is simple. Just modify the datatype to datetime:
ALTER TABLE orders
MODIFY COLUMN order_date datetime;
Sorry about the generic title, I didn't know how to phrase this.
I have a DateTime in my MySQL DB. For example: 14/06/2016 15:01:00
When I try to do a query to find dates which equal certain dates it won't find anything, unless I used the Americanised date format. Yet it's stored in the English way.
Eg:
Select * FROM tbl WHERE Date = '14/06/2016' - Doesn't return any results
But Select * FROM tbl WHERE Date = '2016/06/14' does return results.
Why is this? And how can I swap it around?

The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in 'YYYY-MM-DD HH:MM:SS' format. The supported range is '1000-01-01 00:00:00' to '9999-12-31 23:59:59'.
If you're seeing a different format, your SQL client is "helpfully" changing the output from the underlying data storage.
Im struggling in update the date format in mysql. Before that while retrieval from Mysql(using netbeans) of date using adapter the format was is like that
"Birth_Date": "1990-10-11T00:00:00.000Z",
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
I am working with a mysql database that somebody else created. I have a table with two different date fields one is called eventDate and is in the format YYYY-MM-DD and the other is called creationDate and is in the format M/D/YYYY H:MM:SS AM/PM
What I want to do is query the table and return results where the eventDate is the same as the creationDate but how do I convert the creationDate into YYYY-MM-DD format?
Try STR_TO_DATE() and a format matching the one used by your creationDate strings:
SELECT
…
WHERE DATE(STR_TO_DATE(creationDate, '%c/%e/%Y %r')) = STR_TO_DATE(eventDate, '%Y-%m-%d')
Perhaps MySQL would be able to convert YYYY-MM-DD strings to dates implicitly, so the second STR_TO_DATE() call might be unnecessary.
