工資管理系統c#與SQL Server
表的建立：
Create table Usemen
(
使用者 nchar(10)primary key,
密碼 nchar(10)not null,
性別 nchar(3)not null,
年齡 int notnull,
員工號 nchar(10)not null,
職位 nchar(10)not null
);
Create table Salary
{
基本工資 int notnull,
津貼 int,
總工資 int notnull,
員工號 nchar(10)not null
};
Create teable Work
{
職位 nchar(10)not null,
基本工資 int notnull
};
Create table 價值表
{
職位 nchar(10)not null,
加班費/小時 int not null,
誤工費/小時 int not null
};
Create table 津貼
{
員工號 nchar(10)primary key;
加班時間 int,
誤工時間 int,
加班費 int,
誤工費 int,
獎金 int,
津貼 int
}；
