不多说。

首先是省市区地域建表SQL ：

CREATE TABLE `district_info` (
    	`CODE` VARCHAR(128) NOT NULL COMMENT '编码' COLLATE 'utf8_general_ci',
    	`NAME` VARCHAR(255) NOT NULL COMMENT '地区名称' COLLATE 'utf8_general_ci',
    	`PARENT_CODE` VARCHAR(128) NOT NULL COMMENT '上级地区名称' COLLATE 'utf8_general_ci',
    	`FULL_NAME` VARCHAR(255) NOT NULL COMMENT '当前地区对应的全称' COLLATE 'utf8_general_ci',
    	PRIMARY KEY (`CODE`) USING BTREE
    )
    COMMENT='地区信息表'
    COLLATE='utf8_general_ci'
    ENGINE=InnoDB
    ;

然后是省市区地域数据的sql（自取）：
