复制代码 代码如下:
create table T_Employee(FNumber VARCHAR(20),FName VARCHAR(20),FAge int,FSalary NUMERIC(10,2) ,PRIMARY KEY(FNumber));
insert into T_Employee(FNumber,FName,FAge,FSalary) values('DEV001','Tom',25,8300);
insert into T_Employee(FNumber,FName,FAge,FSalary) values('DEV002','Jerry',28,2300.80);
insert into T_Employee(FNumber,FName,FAge,FSalary) values('SALES001','John',23,5000);
insert into T_Employee(FNumber,FName,FAge,FSalary) values('SALES002','Kerry',28,6200);
insert into T_Employee(FNumber,FName,FAge,FSalary) values('SALES003','Stone',22,1200);
insert into T_Employee(FNumber,FName,FAge,FSalary) values('HR001','Jane',23,2200.88);
insert into T_Employee(FNumber,FName,FAge,FSalary) values('HR002','Tina',25,5200.36);
insert into T_Employee(FNumber,FName,FAge,FSalary) values('IT001','Smith',28,3900);
