MySQL datetime default time with interval

Question

Is it possible to add to a default time with NOW(), 10 minutes?

I've tried something like that:

CREATE TABLE `table1` (
    `date` DATETIME NOT NULL DEFAULT DATE_ADD(NOW(), INTERVAL 10 MINUTE)
);  

However, it doesn't work.

Answer 1

I dont think you can do this.

The MySQL Documentation states that:

The DEFAULT value clause in a data type specification indicates a default value for a column. With one exception, the default value must be a constant; it cannot be a function or an expression. This means, for example, that you cannot set the default for a date column to be the value of a function such as NOW() or CURRENT_DATE. The exception is that you can specify CURRENT_TIMESTAMP as the default for a TIMESTAMP column
