有没有老师写的那个给员工涨工资的完全代码
declare
cursor cemp is select empno ,sal from emp order by sal;
--定义参数
pempno emp.empno%type;
psal emp.sal%type;
countEmp number :=0;
salTotal number;
begin
--得到工资总额的初始值
select sum(sal) into salTotal from emp;
--打开光标
open cemp;
loop
-- 1.工资总额>5w
exit when salTotal>50000;
--取一个员工涨工资
fetch cemp into pempno ,psal;
--2.%notfound
exit when cemp%notfound;
--涨工资
if salTotal+psal*1.1<50000 then
update emp set sal = sal*1.1 where empno=pempno;
--涨工资的人数
countEmp := countEmp+1;
--涨后的工资总额
salTotal := salTotal+psal*0.1;
else exit;
end if;
end loop;
--关闭光标
close cemp;
dbms_output.put_line('涨工资人数:'||countEmp|| '资总额:'||salTotal);
end;
不需要用if 直接加个when就可以了
loop exit when cemp%notfound; fetch cemp into pempno,psal; exit when salTotal > 50000; exit when salTotal+psal*0.1 > 50000; update emp set sal=sal*1.1 where empno=pempno; salTotal := salTotal +psal*0.1; countEmp := countEmp +1; end loop;
