ORA-00947: Not enough values 没有足够的值

Jun 07, 2016 pm 05:27 PM

这里select classno 班级, avg(score) 平均分 into avgScore就出现了问题,改为 create or replace procedure myproc(classno1 i

执行insert的时候出现这个错误。
 
insert into 表1 values (123,2423,12);
 
表1的结构有4个column,显然插入的值只有三个,因此才会出现这个问题。
 
再加个column 的值执行后,ok。
 
倘若只想插入三个数值的话:
 
insert into 表1(a,b,c) values (123,2423,12);
 
用这个语句就可以了。
 
create or replace procedure myproc( cname1 in varchar2, semester1 in varchar2, avgScore out number)
as
begin
select classno 班级, avg(score) 平均分 into avgScore
from student s, course c, student_course_teacher sct
where s.classno=classno1
and c.cname = cname1
and sct.semester = semester1
and s.sno = sct.sno
and c.cno = sct.cno
group by classno;
end;
 
这里select classno 班级, avg(score) 平均分 into avgScore就出现了问题,改为 create or replace procedure myproc(classno1 in varchar2, cname1 in varchar2, semester1 in varchar2, avgScore out number)
 
select avg(score) 平均分 into avgScore 问题得以解决,要注意更新的值的个数与attribute的个数 保持一致。
