tommo74 Posted October 9, 2007 Share Posted October 9, 2007 If I do a select length(name) as length from User and get : length | --------+ | 0 | (2 rows) Does that mean that one of the rows is null and the other one has a value of '' ?

fenway Posted October 9, 2007 Share Posted October 9, 2007 Interesting... LENGTH(null) = NULL, not sure why you're getting blank. Quote Link to comment Share on other sites More sharing options...
lemke411 Posted October 16, 2007 Share Posted October 16, 2007 What I have noticed that MySQL and PHP that blank is null so there would be no result for the length. I don't even think that a 0 will be displayed for the length. Quote Link to comment Share on other sites More sharing options...
