基于Python实现一个简易的数据管理系统

CREATE DATABASE `data_boc` CHARACTER SET 'utf8mb4' COLLATE 'utf8mb4_general_ci';

CREATE TABLE `boc`  (
  `id_` bigint(255) NOT NULL COMMENT '数据记录编号，ID_作为主键',
  `boc_address` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL,
  `boc_code` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL,
  `boc_email` varchar(24) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL,
  `boc_name` varchar(10) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL,
  PRIMARY KEY (`id_`) USING BTREE
)
