項目字典表設計

系統字典表，一半涉及兩張表：字典1：n字典項。是一對多的關系

 

字典表：

 

 字典項表：

 

 如，消息類型，在字典表就是

 

 在字典項對應的多條：

 

 

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 '字典名稱',
  `dict_code` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '字典編碼',
  `description` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '描述',
  `del_flag` int(1) NULL DEFAULT NULL COMMENT '刪除狀態',
  `create_by` varchar(32) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '創建人',
  `create_time` datetime(0) NULL DEFAULT NULL COMMENT '創建時間',
  `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 '更新時間',
  `type` int(1) UNSIGNED ZEROFILL NULL DEFAULT 0 COMMENT '字典類型0為string,1為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;

字典項表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',
  `item_text` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '字典項文本',
  `item_value` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '字典項值',
  `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 '狀態（1啟用 0不啟用）',
  `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;
