ALTER TABLE MODIFY dt_created datetime DEFAULT CURRENT_TIMESTAMP ALTER TABLE mysql default timestamp value to be current timestamp. MySQL recognizes DATE, DATETIME, and TIMESTAMP values in several formats, By default, the current time zone for each connection is the server's time. For numeric types, the default is 0, with the exception that for integer or floating-point types declared with the AUTO_INCREMENT attribute, the default is the.

For more information, see Section By default, the current time zone for each connection is the server's time. The time zone can be set on a per-connection basis. As long as the time zone setting remains constant, you get back the same value you store. This occurs because the same time zone was not used for conversion in both directions. For more information, see Section 5. In MySQL 8. See Section 9. For complete information regarding syntax and additional examples, see the description of the CAST function.

In some cases, this syntax can be deceiving. For example, a value such as '' might look like a time value because of the : , but is interpreted as the year '' if used in date context. The value '' is converted to '' because '45' is not a valid month. The only delimiter recognized between a date and time part and a fractional seconds part is the decimal point.

The server requires that month and day values be valid, and not merely in the range 1 to 12 and 1 to 31, respectively. With strict mode disabled, invalid dates such as '' are converted to '' and a warning is generated. With strict mode enabled, invalid dates generate an error. See Section 5. Dates containing 2-digit year values are ambiguous because the century is unknown. MySQL interprets 2-digit year values using these rules:. Year values in the range become See also Section Numeric Type Attributes.

Out-of-Range and Overflow Handling. Date and Time Data Type Syntax. Simon East Johan Johan Ibrahim: timestamp is your only chance. If you use a datetime field you have to insert record using now everytime. For purposes of storing birth dates, or something more than 30 years in the future for instance. Show 6 more comments.

This should be the accepted answer, but specifically you should edit it to make it obvious it is for a datetime field. The original poster wants to know how to solve it for a datetime field, and use a timestamp is a foolish workaround if you really learn the difference between these two data types.

MySQL before version 5. That said, you can accomplish this by creating a Trigger. I have a table with a DateCreated field of type DateTime. For me the trigger approach has worked the best, but I found a snag with the approach. Consider the basic trigger to set a date field to the current time on insert:. What happens is that the trigger immediately overwrites your provided value for the field, and so the only way to set a non-current time is a follow up UPDATE statement--yuck!

This gives the best of both worlds: you can provide a value for your date column and it will take, and otherwise it'll default to the current time. This works as you would expect the now function to work. So here is is:. MySQL 5. As a sidenote , it is mentioned in the mysql docs :. The DATE type is used for values with a date part but no time part. The supported range is '' to ''.

You can use now to set the value of a datetime column, but keep in mind that you can't use that as a default value. These properties are described later in this section. I believe the only solution on the database side is to use triggers like mentioned in other answers. While defining multi-line triggers one has to change the delimiter as semicolon will be taken by MySQL compiler as end of trigger and generate error. I think it simple in mysql since mysql the inbuilt function called now which gives current time time of that insert.

You can resolve the default timestamp. First consider which character set you are using for example if u taken utf8 this character set support all languages and if u taken laten1 this character set support only for English. Next setp if you are working under any project you should know client time zone and select you are client zone. This step are mandatory.

This is too trivial a use case for a trigger, although it is a solution. John Larson John Larson 1, 1 1 gold badge 8 8 silver badges 8 8 bronze badges.

I personally think this is the best way to go. Never mind, I figured it out. Forgot to set the field to allow NULL. No warnings anymore. Triggers are evil! Only ever use them when there's no other way of doing something. Better to upgrade to 5. In MySQL 5. I was able to solve this using this alter statement on my table that had two datetime fields. I meant to say, If you insert records via the MySQL query browser manually via the grid without an insert statement the trigger is needed.

If you always use an insert statement the trigger is completely unnecessary. I meant The trigger name can be whatever you want it to be because the trigger name doesn't affect the functionality at all. Most people will know that, but some folks new to MySQL might not know Yikes, sorry about the lack of line breaks. Use the semi-colons to mark the end of each line. In Table Editor go to Foreign Keys tab at the bottom. Keys are displayed in the left pane and details of selected keys are displayed on the right.

You can see pair of foreign and primiary columns in Column and Referenced Column columnsin the grid in the middle of the window. The default value will be added to all new records, if no other value is specified. In MySQL integer int 11 has size is 4 bytes which equals 32 bit.

Default values are the values assigned to variables when no specific value is explicitly assigned in the program. In uniPaaS you can define the default values. Can you change the default column in MySQL? Workbench cannot override this limitation.
