项目字典表设计

系统字典表，一半涉及两张表：字典1：n字典项。是一对多的关系

字典表：

 字典项表：

 如，消息类型，在字典表就是

 在字典项对应的多条：

字典表sql：

CREATE TABLE `sys_dict`  (
  `id` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `dict_name` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '字典名称',
  `dict_code` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '字典编码',
  `description` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '描述',
  `del_flag` int(1) NULL DEFAULT NULL COMMENT '删除状态',
  `create_by` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '创建人',
  `create_time` datetime(0) NULL DEFAULT NULL COMMENT '创建时间',
  `update_by` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '更新人',
  `update_time` datetime(0) NULL DEFAULT NULL COMMENT '更新时间',
  `type` int(1) UNSIGNED ZEROFILL NULL DEFAULT 0 COMMENT '字典类型0为string,1为number',
  PRIMARY KEY (`id`) USING BTREE,
  UNIQUE INDEX `indextable_dict_code`(`dict_code`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

字典项表sql：

CREATE TABLE `sys_dict_item`  (
  `id` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `dict_id` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '字典id',

  `description` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '描述',
  `sort_order` int(10) NULL DEFAULT NULL COMMENT '排序',
  `status` int(11) NULL DEFAULT NULL COMMENT '状态（1启用 0不启用）',
  `create_by` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `create_time` datetime(0) NULL DEFAULT NULL,
  `update_by` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `update_time` datetime(0) NULL DEFAULT NULL,
  PRIMARY KEY (`id`) USING BTREE,
  INDEX `index_table_dict_id`(`dict_id`) USING BTREE,
  INDEX `index_table_sort_order`(`sort_order`) USING BTREE,
  INDEX `index_table_dict_status`(`status`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;
