Current time when MySQL record is saved to database

问题

I'm working with Zend Framework 1.12 and Mysql. I want to add column in database, which save currenct datetime when record was inserted into table.

Anyone knows how can I defined this column? This function must working on Mysql site, not PHP.

回答1:

you must change column type to TIMESTAMP , and in default field set CURRENT_TIMESTAMP

回答2:

There are different ways to do so.

You can define data type TIMESTAMP and set default value to CURRENT_TIMESTAMP

You can define column with data type datetime and use now() or sysdate() to get current date and time.

For eg.

 INSERT INTO `table_name`(current_time) VALUES(now());

or

 INSERT INTO `table_name`(current_time) VALUES(sysdate());

You can just define the column like:

DATETIME DEFAULT CURRENT_TIMESTAMP
