I create a table with a datatime field, it's default value is CURRENT_TIMESTAMP;

Heidisql will change it's default value to now() automatic;

When i modify some column of the table, it will raise an error cause that datetime field's default value is now()

I do not konw how to avoid this situation and why?

HeidiSQL itself does not do that, I guess the server does. However, altering the table again should not result in an error. What server version is it? And please ensure you have the latest HeidiSQL version.

when i create tabel in command line, CURRENT_TIMESTAMP always CURRENT_TIMESTAMP; but in heidisql ui, it automatic change to now()
