I have the current date format [DD_MM_YYY] in a column on my table and would like to change it to [YYYY_MM_DD]. Can't seem to figure out the correct syntax.
This one should do for date fields:
SELECT DATE_FORMAT(NOW(), '%Y-%m-%d');
You can use the convert function in sql.
SELECT CONVERT (data_type(length)),Date, DateFormatCode)
To convert in this format [YYYY_MM_DD] if the date format is in varchar:
Select CONVERT(varchar,column_name,23)
If you are using Exasol, you can use to_date():
select to_date(datecoll, 'DD_MM_YYYY')
I would recommend leaving this as a date. But if you want to convert this back to a string:
select to_char(to_date(datecoll, 'DD_MM_YYYY'), 'YYYY-MM-DD')

I have a specific date in the format of YYYY-MM-DD but want to convert it to YYYY-MM format in a table. I want this change to apply to the full table. can anyone help me out, please?
Thank you.
Assuming that you have a date datatype or the-like (datetime, timestamp), you can use date_format() to represent your date in the target format:
date_format(mydate, '%Y-%m')
This returns a string in the target format. It does not make sense to convert your date column to a string though. Keep that column as it is, and maybe use a computed column to automatically derived the string representation you want:
create table mytable (
...
mydate date,
mynewcol varchar(7) as (date_format(mydate, '%Y-%m'))
)
You can use DATE_FORMAT function of MySQL, for more information please visit
SELECT DATE_FORMAT("2017-06-15", "%Y-%m");
I'm have a table where I'm capturing login and logout time from front end application. The login and logout time is sitting in the database in this format 1/24/2019 13:22:22, now I need only date from it.
So that I can use to retrieve data based on the particular date i.e., I can use select statement with where clause giving the date and getting the data.
Can anyone help me in converting this. I'm using varchar field to store the input value coming from front end.
This is the table and based on the login1 field date i need to retrieve the data.
I'm able to do the query required for getting the data as I needed
SELECT * FROM timesheet where login1 LIKE '%1/24/2019%'
You need to cast or convert as a VARCHAR datatype, you can try below query to get only the date.
SELECT CAST('1970-01-01 00:00:00-08:00' as DATE) as DATE1 FROM dual;
You can try below -
select date(STR_TO_DATE(login1, '%m/%d/%Y %H:%i:%s'))
You can do it in this way also-
select * FROM Login WHERE date_format(STR_TO_DATE(logindate, '%m/%d/%Y %H:%i:%s'), '%m/%d/%Y') = date('01/18/2019')
I'm querying
SELECT * FROM tempLog WHERE date BETWEEN '23-03-2017' AND '02-04-2017'
and the result is null. How to fix this. But
SELECT * FROM tempLog WHERE date BETWEEN '23-03-2017' AND '30-03-2017'
giving me the correct result.
Note:- tempLog is the table name.
You should store dates in date format or atleast correctly formatted string (YYYY-MM-DD).
For now you can use str_to_date to convert the string to date and compare:
select *
from tempLog
where str_to_date(date, '%d-%m-%Y') between '2017-03-23' and '2017-04-02';
However note that this will hinder the optimizer from using index on the column if any.
The correct remedy of the situation is fixing the table structure.
According to the documentation, you're supposed to use this format when writing a date: 'YYYY-MM-DD' (although it says it may accept 'YYYYMMDD' or even YYYYMMDD in some contexts).
I have a table in MYSQL of which 3 columns have dates and they are formatted in the not desired way.
Currently I have: mm/dd/yyyy and I want to change those dates into dd/mm/yyyy.
Table name is Vehicles and the columns names are:
CRTD
INSR
SERD
Your current datatype for your column is not date right? you need to convert it to date first using STR_TO_DATE() and convert back to string
SELECT DATE_FORMAT(STR_TO_DATE(colName, '%c/%d/%Y'), '%d/%c/%Y')
FROM table1
SQLFiddle Demo
try this:
select date_format(curdate(), '%d/%m/%Y');
In you case you have to use this query.If all three columns are of datetime type
select date_format(CRTD, '%d/%m/%Y'),
date_format(INSR, '%d/%m/%Y'),
date_format(SERD, '%d/%m/%Y')
From yourTable
You can use the date_format() function to format your dates any way you want.
If you want to change the format for every date on any database you work with, you should change the value of the date_format system variable.
UPDATE Vehicles SET yourdatecolumn=DATE_FORMAT(STR_TO_DATE(yourdatecolumn, '%c-%d-%Y'), '%d-%c-%Y')
How do you change date format from yy-mm-dd to day-month-year?
I have tried this:
UPDATE stock
SET date_in = DATE(STR_TO_DATE(date_in, '%d/%m/%Y))
WHERE DATE(STR_TO_DATE(date_in, '%d/%m/%Y') <> '00-00-0000';
But it is giving me an error.
You store dates in database in one of the date formats (date,datetime,timestamp)
When you want to format them for view, either use your language, which surly has a date formatting functionality, or use the intrinsic mysql date_format in a SELECT statment
