Auto generated date in mysql

I have a table where I have a date column. Is there a way for MySQL to auto fill this field whenever I insert a new registry with the current date? Or is this made automatically by default?

P.S.: I'm using PHPMyAdmin

Although it is an old post, maybe this image will help as it is more explicit: (For phpMyAdmin users)

Auto generated date in mysql

This configuration sets that field with a value like:

2015-12-11 07:50:47

PS: Note that the timestamp will set the time OF your server!! (i.e. the example above got the time from Pacific Time (07:50:47) but it could have been from a Spanish user at 16:50:47 local time) Keep this in mind.

Also, if you already have a "Created Date" you might need another column that updates the modification date whenever there is an update: You only need to set on update CURRENT TIME STAMP in Attributes Field.

Ready to rock!

you have to use

now()

function where you want to fill current time.

i.e.:

INSERT INTO  user_rights (`user_id`,`right`,`group_id`,`created_date`) VALUES ( '42',  '160',  '1',  now());

I realize this may not be a direct answer to the question but I do believe this is the most useable solution.

I highly recommend using a DATETIME or TIMESTAMP data type for the column in question.
If you are utilizing a fairly current version of MySQL, MySQL will do the work for you.

Details:
To be very clear, as of 5.6.5, for both the TIMESTAMP & DATETIME datatypes, you can do the following:

  1. Set a DEFAULT value of the current date & time (using NOW() or one of its aliases such as CURRENT_TIMESTAMP)
    This means every time you insert a new row into this table a TIMESTAMP or DATETIME column with this default will get the current date and time
  2. Set an ON UPDATE constraint that will UPDATE a column to the current date & time when, (you guessed it) the row is updated

Here's how:
An Example in a CREATE TABLE statement:

CREATE TABLE t1 (
ts1 DATETIME ON UPDATE CURRENT_TIMESTAMP
,ts2 DATETIME DEFAULT NOW()
);

Please note that DATETIME can be replaced with TIMESTAMP for effectively the same functionality.
Additionally I suggest the use of the DATETIME data type over TIMESTAMP as DATETIME has a much larger range of dates it can support. It's worth mentioning that TIMESTAMP is smaller for those few cases that matters.

I have added this to my table and it works

ALTER TABLE Medewerkers ADD med_created TIMESTAMP DEFAULT now(); 

When you insert data into your record it update automatically the med_created

MySQL unfortunately doesn't allow specifying values other than constants as the default for columns other than TIMESTAMPs.

This is a feature available in MySQL versions 8.0+, but for older versions the only solution for a database defined default would be to use a trigger.

You can do something like this from the SQL screen

ALTER TABLE `table_name` CHANGE `created_at` `created_at` TIMESTAMP NOT NULL

How do I automatically insert date in MySQL?

You can use now() with default auto fill and current date and time for this. Later, you can extract the date part using date() function. Let us set the default value with some date.

Can you auto increment date in MySQL?

There is no built-in way to auto-increment date time, cause that field is something that a user defines.

How do I insert date in YYYY

Introduction to MySQL DATE data type This format is fixed and it is not possible to change it. For example, you may prefer to use mm-dd-yyyy format but you can't. Instead, you follow the standard date format and use the DATE_FORMAT function to format the date the way you want. MySQL uses 3 bytes to store a DATE value.

How do I automatically insert the date in PHPMyAdmin?

To add a date information in PHPMyAdmin you need to log in the PHPMyAdmin interface and then to enter the 'Insert' tab. Then you can choose the appropriate Insert functions for each field using the drop-down list in the functions column.
