每当我在网页中执行查询时，如何使用当前日期更新phpmyadmin中定义为日期的字段？

Question

I have added a query in my website php page. It looks like something...

mysql_select_db("my_db", $con); 

$sq2="INSERT INTO querylog(QueryID, Module, AskedBy, Date)
VALUES
('', '$_POST[Module]', '$_POST[Name]', '')";

$row = !mysql_query($sq2,$con)

I want 'Date' column to update automatically in phpmyadmin table. Not sure how to proceed.

Answer 1

You can either set the default for the column to be NOW() or just insert NOW() with your query.

$sq2 = "INSERT INTO querylog (QueryID, Module, AskedBy, `Date`)
    VALUES ('', '$_POST[Module]', '$_POST[Name]', NOW())";

Please, don't use mysql_ functions in new code. They are no longer maintained and are officially deprecated.

Answer 2

One possible solution could be to change your date column to a timestamp. http://dev.mysql.com/doc/refman/5.5/en/timestamp-initialization.html

An alternate solution would be to use a trigger.

http://dev.mysql.com/doc/refman/5.0/en/triggers.html

In phpMyAdmin open up the SQL tab and paste something like:

DELIMITER $$
CREATE TRIGGER autoSetDate BEFORE INSERT ON yourDatabaseName.yourTableName
FOR EACH ROW
BEGIN
    NEW.date=NOW();
END; $$
DELIMITER ;
