--直接创建索引
CREATE INDEX IDX_GROUP_NAME ON base_group(GROUP_NAME);
或
CREATE INDEX IDX_GROUP_NAME ON base_group(GROUP_NAME(50));

--修改表结构的方式添加索引
ALTER TABLE base_group ADD INDEX IDX_GROUP_NAME(GROUP_NAME);
或
ALTER TABLE base_group ADD INDEX IDX_GROUP_NAME(GROUP_NAME(50));

--创建表的时间指定索引
CREATE TABLE `base_group` (
    `id` int(11) NOT NULL AUTO_INCREMENT ,
    `group_name` varchar(255) NOT NULL ,
    `content` text NULL ,
    `time` int(10) NULL DEFAULT NULL ,
    PRIMARY KEY (`id`),
    INDEX index_name (group_name(50))
)

--删除索引
DROP INDEX IDX_GROUP_NAME ON base_group;
