我得到的错误： 在此处输入图像描述
该错误在过程中的“插入”语句中引发。目标表具有与插入语句中相同的列数和数据类型。
我的程序是：
create or replace procedure updatetax
is
date_30 date:=sysdate-(365*30);
date_50 date:=sysdate-(365*50);
/*employees less than 30 years of age*/
cursor c1 is
select eid
from employee
where dateofbirth>date_30
and enddate is null;
/*employees between the age of 30 and 50*/
cursor c2 is
select eid
from employee
where dateofbirth between date_50 and date_30;
/*employees greater than 50 years of age*/
cursor c3 is
select eid
from employee
where dateofbirth<date_50;
r1 employee.eid%type;
r2 employee.eid%type;
r3 employee.eid%type;
begin
open c1;
for r1 in c1
loop
insert into emptax
values(r1.eid,gettaxlessthan30(select salary from empsalary where eid=r1.eid),sysdate);
end loop;
close c1;
commit;
open c2;
for r2 in c2
loop
insert into emptax
values(r2.eid,gettaxbetween30and50(select salary from empsalary where eid=r2.eid),sysdate);
end loop;
commit;
open c3;
close c2;
for r3 in c3
loop
insert into emptax
values(r3.eid,gettaxgreaterthan50(select salary from empsalary where eid=r3.eid),sysdate);
end loop;
commit;
close c3;
end;
/
存储过程中调用的函数的逻辑如下：
create or replace function gettaxlessthan30(esalary_in number)
return number
is
tax_out number(10,2);
begin
tax_out:=0.07*esalary_in;
return tax_out;
end;
