(
用户 nchar(10)primary key,
密码 nchar(10)not null,
性别 nchar(3)not null,
年龄 int notnull,
员工号 nchar(10)not null,
职位 nchar(10)not null
);
Create table Salary
{
基本工资 int notnull,
津贴 int,
总工资 int notnull,
员工号 nchar(10)not null
};
Create teable Work
{
职位 nchar(10)not null,
基本工资 int notnull
};
Create table 价值表
{
职位 nchar(10)not null,
加班费/小时 int not null,
误工费/小时 int not null
};
Create table 津贴
{
员工号 nchar(10)primary key;
加班时间 int,
误工时间 int,
加班费 int,
误工费 int,
奖金 int,
津贴 int
}；
