问题 I have a column eventDate which contains trailing spaces. I am trying to remove them with the PostgreSQL function TRIM() . More specifically, I am running: SELECT TRIM(both ' ' from eventDate) FROM EventDates; However, the trailing spaces don't go away. Furthermore, when I try and trim another character from the date (such as a number), it doesn't trim either. If I'm reading the manual correctly this should work. Any thoughts? 回答1: There are many different invisible characters. Many of them
