mycat执行如下脚本报错 ：1064 - syntax error, error in :'Id`) USING BTREE
DROP TABLE IF EXISTS `score`;
CREATE TABLE `score` (
`Id` int(11) NOT NULL AUTO_INCREMENT,
`Name` varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NULL DEFAULT NULL,
`grade` int(11) NULL DEFAULT NULL,
`Remark` varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NULL DEFAULT NULL,
PRIMARY KEY (`Id`) USING BTREE,
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_unicode_ci ROW_FORMAT = Compact;
解决方法，将最后两句更改为
DROP TABLE IF EXISTS `score`;
CREATE TABLE `score` (
`Id` int(11) NOT NULL AUTO_INCREMENT,
`Name` varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NULL DEFAULT NULL,
`grade` int(11) NULL DEFAULT NULL,
`Remark` varchar(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci NULL DEFAULT NULL,
PRIMARY KEY (`Id`),
KEY `Id` USING BTREE(`Id`)
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_unicode_ci ROW_FORMAT = Compact;
