原因是mysql.proc 在5.1 comment char(64) -> 5.5 comment text 導致

The difference seen in the mysql.proc table is
5.5
< `comment` text CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
---
5.1
> `comment` char(64) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT ‘‘,


我們僅僅須要將table proc column comment 改為text類型就能夠了

ALTER TABLE `proc`
MODIFY COLUMN `comment` text CHARACTER SET utf8 COLLATE utf8_bin NOT NULL;
