drop table if exists tb_user;
create table tb_user(userID varchar(20),password varchar(20),position int
);
warehouse类
点击查看代码 
CREATE TABLE warehouse (warehouseCode VARCHAR(50) UNIQUE NOT NULL ,  -- 仓库编码，唯一且不能为空warehouseName VARCHAR(100) NOT NULL,        -- 仓库名称，不能为空location VARCHAR(200),                      -- 仓库地址capacity DECIMAL(10, 2),                    -- 仓库容量，可存储数值，例如存储货物的重量或体积contactPerson VARCHAR(50),                 -- 仓库联系人contactPhone VARCHAR(20)                   -- 联系人电话
);
material_category类
点击查看代码 
CREATE TABLE material_category (materialCode VARCHAR(50) NOT NULL UNIQUE PRIMARY KEY,materialName VARCHAR(100) NOT NULL,specification VARCHAR(100),material VARCHAR(100),-- 可根据需求添加其他字段，如备注等remarks TEXT
);
material_ledger_detail类
点击查看代码 
CREATE TABLE material_ledger_detail (-- 台账编号，作为主键，唯一标识每条记录ledgerId VARCHAR(12) PRIMARY KEY NOT NULL,-- 物资编码，用于关联物资类别表，不允许为空materialCode VARCHAR(50) NOT NULL,-- 操作类别，使用 ENUM 类型限制为 '入库' 或 '出库'，不允许为空operationType ENUM('入库', '出库') NOT NULL,-- 物资数量，使用 DECIMAL 类型存储，精度为 10，小数位为 2，不允许为空quantity DECIMAL(10, 2) NOT NULL,-- 计量单位，如 '个'、'箱' 等，不允许为空unit VARCHAR(20) NOT NULL,-- 存放地点（仓库号），不允许为空storageLocation VARCHAR(20) NOT NULL,-- 操作日期，记录操作发生的时间，默认值为当前时间operationDate TIMESTAMP DEFAULT CURRENT_TIMESTAMP
