我在MySQL的创建过程中遇到了这个错误。我的操作如下:
CREATE TABLE `blogReply` (
`Id` INT(24) NOT NULL AUTO_INCREMENT COMMENT 'Primary Key of This Table',
`blogId` INT(24) NOT NULL COMMENT 'Blog where this reply was posted',
`userId` INT(24) NULL COMMENT 'User the blog was posted by',
`name` VARCHAR(100) NULL DEFAULT 'Unknown' COMMENT 'The Name of the user that the reply was posted by',
`email` VARCHAR(100) NULL DEFAULT 'Unknown' COMMENT 'The Email of the user that the reply was posted by',
`http` VARCHAR(300) NULL DEFAULT 'Unknown' COMMENT 'The Webaddress of the user that the reply was posted by',
`message` TEXT NOT NULL COMMENT 'text of the blog',
`votes` INT(10) DEFAULT 0 COMMENT 'Rating of the Blog',
`ratedBy` TEXT COMMENT 'People who have already Voted on this blog',
`dateReg` BIGINT NOT NULL COMMENT 'Date the User was Registered',
PRIMARY KEY (`Id`),
CONSTRAINT `FK_userId` FOREIGN KEY(`userId`)
REFERENCES `user` (`Id`)
ON DELETE SET NULL
ON UPDATE CASCADE,
CONSTRAINT `FK_blogId` FOREIGN KEY(`blogId`)
REFERENCES `blog` (`Id`)
ON DELETE CASCADE
ON UPDATE CASCADE
) ENGINE = InnoDB;
有什么想法吗?错误提示为:无法创建'./xxxxxxxx/blogReply.frm'表(错误号:121)
