This looks to be a feature, not a bug. :) >From http://www.mysql.com/doc/B/L/BLOB.html: "There is no trailing-space removal for BLOB and TEXT columns when values are stored, as there is for VARCHAR columns." Additionally, from the CHAR and VARCHAR section: "When CHAR values are stored, they are right-padded with spaces to the specified length. When CHAR values are retrieved, trailing spaces are removed. [...] However, in contrast to CHAR, VARCHAR values are stored using only as many characters as are needed, plus one byte to record the length. Values are not padded; instead, trailing spaces are removed when values are stored. (This space removal differs from the ANSI SQL specification.)" -- denonymous www.coldcircuit.net denonymous.ne.mediaone.net --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
