drawbacks of not being specific?

[scarhand]

do i have to be specific when setting datatypes, or is it ok to just use

 

CREATE TABLE tabratings (
  ratingid int unsigned NOT NULL auto_increment,
  tabid int NOT NULL,
  raterrid int NOT NULL,
  rating int NOT NULL,
  PRIMARY KEY (ratingid)
);

 

ive always done things this way....any experts give a problem with this?

That's very specific.

That's very specific.

 

mean instead of using int(20) i am just using int.....

int(20) doesn't actually do anything... not as far as the data are concerned.
