I am currently exploring a CSV dataset with 6 different tables on MYSql
enter image description here
I am unable to Format the date column in mm-dd-yyyy format. I tried using convert() & CAST() function but still does not workout
Can anyone guide me?
SELECT
date,
CONVERT(VARCHAR(255), date, 103) AS "new_date",
FROM production_sales_forecast;
SELECT CAST(date as DATE)
FROM
production_sales_forecast;
I just want the entire column to be formatted in dd-mm-yyyy
In MySQL you can use STR_TO_DATE to convert a string to date and DATE_FORMAT to format the date value according to the format string.
SELECT STR_TO_DATE("3/1/2020", "%e/%m/%Y");
SELECT DATE_FORMAT(STR_TO_DATE("3/1/2020", "%e/%m/%Y"),"%m-%d-%Y") as my_new_date ;

So I'm trying to insert dates into a table and the date is in this format:
8/3/2021
However I want to add a leading 0 before the month and day so the date shows 08/03/2021. Also I want to add it as a string concatenated with another string so test123-08/03/2021
If you really store date in that format then you may try this:
SELECT
DATE_FORMAT(STR_TO_DATE(date_col_string,'%d/%m/%Y'),'%d/%m/%Y') as 'zero-padded',
CONCAT(string_val,'-',DATE_FORMAT(STR_TO_DATE(date_col_string,'%d/%m/%Y'),'%d/%m/%Y')) as 'concatenated'
FROM mytable;
Use STR_TO_DATE() function to change the date value to standard MySQL date format of YYYY-MM-DD then use DATE_FORMAT() function to display the date value as per your desired output. The second operation is adding CONCAT() function on the converted date with your selected string. I'm assuming that your date value is d/m/y, because as #Stu mentioned in the comment, since you're not storing as MySQL standard date format, that means 8/3/2021 can be either d/m/y or m/d/y. With a standard date format value, the query would be shorter:
SELECT
DATE_FORMAT(date_col,'%d/%m/%Y') as 'zero-padded',
CONCAT(string_val,'-',DATE_FORMAT(date_col,'%d/%m/%Y')) as 'concatenated'
FROM mytable;

You should be inserting your source dates into a proper date or datetime column. Then, to view your dates in the format you want, use the DATE_FORMAT() function with the appropriate format mask:
SELECT DATE_FORMAT(date_col, '%d/%m/%Y') AS date_out
FROM yourTable;
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'm trying to convert a string to date with a format of yyyy/mm to yyyy
STR_TO_DATE(SUBSTRING(time,1,4), '%Y')
This returns null for every value as well as when I try to convert without getting rid of the mm:
STR_TO_DATE(REPLACE(time,'/',''), '%Y%m')
This method has worked for me before, I'm at a loss for what I'm missing.
Thanks in advance!
Edit for clarification:
Eventually I am going to insert the year into a column with data type year, so I need to convert a varchar to a date type so I can extract the year in order to insert the data into a new table
I am in the process of making sure it will work before populating the new column with a command like this:
INSERT INTO table (year)
SELECT STR_TO_DATE(SUBSTRING(time,1,4), '%Y')
FROM `origtable`
I'm trying to convert a string to date with a format of yyyy/mm to yyyy
Just use left():
select left(time, 4) as yyyy
There is no need to convert to a date or datetime. You want a simple string operation.
EDIT:
year is a really weird type. I would just use an integer. But if you are using it, you can insert a full date into the field:
select date(concat(time, '/01'))
The resulting date can be inserting to a year column.
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.
