Delete empty rows

Question

I use PostgreSQL database and in one table I have the datetime column edit_user. Some rows are blank, and these rows I would like to delete.

I tried

DELETE FROM table WHERE edit_user=""; 

but I got the error

LINE 1: delete from table where edit_user="";

Also, I thought in the column as a blank value could be 0000-00-00, but there isn't.

How I should execute this command correctly?

Answer 1

DELETE FROM table WHERE edit_user IS NULL;
