mysql出现Cannot load from mysql.proc
- 日期 : 2014-07-09
在5.1中mysql.proc表的comment字段是char(64)：
`comment` char(64) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL DEFAULT '',
但在5.5中应该是text：
`comment` text CHARACTER SET utf8 COLLATE utf8_bin NOT NULL, So，执行下面的语句，把这个字段修改为text，就彻底OK了：
ALTER TABLE `proc`
MODIFY COLUMN `comment` text CHARACTER SET utf8 COLLATE utf8_bin NOT NULL AFTER `sql_mode`;
