ERROR 1067 (42000): Invalid default value for 'created_at'

Question

When I tried to alter the table it showed the error:

ERROR 1067 (42000): Invalid default value for \'created_at\'

I googled for this error

Answer 1

Try and run the following command:

ALTER TABLE `investments` 
MODIFY created_at TIMESTAMP 
DEFAULT CURRENT_TIMESTAMP 
NOT NULL;

and

ALTER TABLE `investments` 
MODIFY updated_at TIMESTAMP 
DEFAULT CURRENT_TIMESTAMP 
NOT NULL;

The reason you are getting this error is because you are not setting a default value for the created_at and updated_at fields. MySQL is not accepting your command since the values for these columns cannot be null.

Hope this helps.
