is there any possible way to store current time only via phpmyadmin in mysql

Question

I want to store current time (for example 00:30) in one of my column , the default CURRENT_TIMESTAMP gives both date and time which i dont want.

or is there any way of retrieving only time from CURRENT_TIMESTAMP ??

Answer 1

Try combining TIME() and NOW() :

SELECT TIME(NOW());

Output: 15:20:31

Of course, your column will need to be of type " TIME ".

Answer 2

You can use MySQL's built-in TIME() function to extract the time part of a datetime expression. For example:

mysql> select time(now());
+-------------+
| time(now()) |
+-------------+
| 18:21:38    |
+-------------+
1 row in set (0.03 sec)

Since CURRENT_TIMESTAMP is a synonym for NOW() , you can just use TIME(CURRENT_TIMESTAMP) .

Answer 3

创建表时，将列类型设置为TIME

Answer 4

If I understand your question correctly, I think you have a timestamp column that has a default value of CURRENT_TIMESTAMP:

CREATE TABLE yourTable (
  ...,
  ...,
  currentTime TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

If you just want to store the current time, and not the date part, you could use a TIME column and trigger, that will insert the time part automatically:

CREATE TABLE tableName (
  ...,
  ...,
  currentTime TIME
);

CREATE TRIGGER currentTime BEFORE INSERT ON tableName
FOR EACH ROW
  SET new.currentTime = TIME(NOW());

(an example is here ) and you might also want to use an UPDATE trigger. Or you can just use CURRENT_TIMESTAMP, and get only the time part with TIME function:

SELECT TIME(yourTimestampColumn)
FROM yourTable
