eMonk Posted April 25, 2011 Share Posted April 25, 2011 My book recommends using char over varchar because it will keep the database smaller and it's faster to phrase. So why is everyone using varchar? Link to comment https://forums.phpfreaks.com/topic/234690-char-vs-varchar/ Share on other sites More sharing options...
Maq Posted April 25, 2011 Share Posted April 25, 2011 My book recommends using char over varchar because it will keep the database smaller and it's faster to phrase. So why is everyone using varchar? They're stored differently and CHAR can only hold up to 30 characters.

mikosiko Posted April 25, 2011 Share Posted April 25, 2011 ... CHAR can only hold up to 30 characters. ... oops!! char() ... 0-255 varchar() 0-65535 main difference (other than the size limit) is the way that both are stored char() is fixed length (right-padded) and varchar() is variable length Link to comment https://forums.phpfreaks.com/topic/234690-char-vs-varchar/#findComment-1206054 Share on other sites More sharing options...

raindropz12 Posted April 26, 2011 Share Posted April 26, 2011 what is the difference between fixed-length and variable-length? Link to comment https://forums.phpfreaks.com/topic/234690-char-vs-varchar/#findComment-1206316 Share on other sites More sharing options...
fenway Posted April 26, 2011 Share Posted April 26, 2011 The refman covers it all -- there are dozens of other subtle differences (trimming, index implications, etc.). More importantly, one variable-length column means you can't have any CHAR fields anymore.
