I have a column values like 20150921. I want to convert this string value to a specified date format like 2015-09-21 in mysql.
Try this:
date_format(str_to_date('20150921', '%Y%m%d'),'%Y-%m-%d')
SQL FIDDLE DEMO
(Assuming that you want your date format to be in YYYY-MM-DD format)
I am able to run this query on my MySql 5.6.
SELECT DATE('20150921');
So i believe, this should work directly DATE(colStringDate)

Hi I have a date column in mysql (actually it's SQuirreL, but basically it's mysql),and the data type of this column is integer and has format like 1170101, anyone knows how can I convert it to mysql date format 2017-01-01 in mysql so mysql can recognize it?
Thank you.
Try this.
date(concat(1170101 + 19000000))
You can test using this sql.
select date(concat(1170101 + 19000000));
Basically my date in MySql table looks like this
2001-04-16
The format is actually day-month-year. Unfortunately 20 is added to the date. So finally i should update this date. This should become
01-04-2016
How to update my all date format in my table
Don't change this in the database, change it when you need to display it. The ISO date format is what's used internally and should be kept that way, it's the most native, efficient format, and it sorts correctly.
You can select them out:
SELECT DATE_FORMAT(date_column, '%d-%m-%Y') FROM table_name
Using the DATE_FORMAT() function.
Even better is to do this in your application layer, whatever that is, using a date formatting function tuned to the user's locale.
If you've got a bunch of bad data in your database you need to convert, you can re-write it with the DATE_FORMAT() function to strip out the mistakes.
For example:
UPDATE table_name SET date_column=DATE_FORMAT('20%d-%m-%y', date_column)
For mysql, MySQL retrieves and displays DATE values in 'YYYY-MM-DD' format. so you can fetch date in whatever format you want from database, please see https://dev.mysql.com/doc/refman/5.6/en/datetime.html for more info.
you can use DATE_FORMAT() function :
SELECT DATE_FORMAT('%d-%m-%Y', date) as desired_date FROM table_name where 1
I got in my table two types:
hour_Event in type date
date_Event in type datetime
I would like hour_Event to be formatted to hh:mm
and date_Event to be dd/mm/yyyy
I use PHPMyAdmin and im new with MySQL so I dont know how to change the format and for what.
How do I do it?
**DATE_FORMAT(hour_Event,'%h:%i')** will give you hour_Event in hh:mm
and
**DATE_FORMAT(date_Event,'%d/%m/%Y')** will give you date_Event in dd/mm/yyyy
You could change the format using php before you insert data or after retrieving themfrom your database according to your needs.You could use DateTime / strtotime() & date(). In most cases a single timestamp field in your table is enough for an event.
Have a look here:
Convert one date format into another in PHP
Also you could format your field according to your needs with mysql for example:
DATE_FORMAT(tables.field, '%d-%m-%Y %H:%i:%s') AS 'new_name'

How to Create a colummn DATE with format DD/MM/YYYY?
Mysql come for defaut with this formar YYY/MM/DD.
I need isert via HTML5 date Day/Month/Year, for this format come in DD/MM/YYYY
On your insert/select statements, you can convert MySQL Date Functions:
SELECT ... DATE_FORMAT(field,'%d/%m/%Y');
INSERT ... STR_TO_DATE('formatteddate','%d/%m/%Y')
you can check your js file if any,corresponding to date and change format to MySQL database format
I guess you could save it as a varchar, but that's messy. Your best option is to have MySQL save the date in the default format, then simply format the date to DD/MM/YYYY upon retrieval.
I have a query from within my vb.net code which searchs for a record by date. The date being entered via the code is in format dd/mm/yyyy, i need to search in the database using yyyy/mm/dd?
Ideally i thought there may just be a function within MySQL which will convert this. If not in vb.net to convert the string 01/01/2011 to 2011/01/01?
Thanks
Take a look at str_to_date() function
select str_to_date('01/01/2011','%d/%m/%Y')
So, your search becomes
select * from table where date_field = str_to_date(your_variable,'%d/%m/%Y')
