ORA-00913错误:PL/SQL: ORA-00913: too many values

ORA-00913错误

描述:PL/SQL: ORA-00913: too many values

目标:编写一个可以循环插入数据的脚本

操作过程:
SQL> desc tcustmer
Name Null? Type
----------------- -------- ----------------------------
CUST_CODE NOT NULL VARCHAR2(10)
NAME VARCHAR2(30)
CITY VARCHAR2(20)
STATE CHAR(2)

SQL>CREATE SEQUENCE tcustmer_cust
INCREMENT BY 1
START WITH 1
MAXVALUE 100000000
CACHE 10000
NOCYCLE;

SQL> begin
2 for i in 1..10 loop
3 insert into tcustmer
4 values (tcustmer_cust.nextval,'T','test'||i,'BEIJING','CN');
5 if mod(i,10)=0 then
6 commit;
7 end if;
8 end loop;
9 commit;
10 end;
11 /
insert into tcustmer
*
ERROR at line 3:
ORA-06550: line 3, column 20:
PL/SQL: ORA-00913: too many values
ORA-06550: line 3, column 8:
PL/SQL: SQL Statement ignored

检查发现插入的values值,,列数超过了tcustmer表的列数
调整如下:
SQL>begin
for i in 1..10 loop
insert into tcustmer
values ('T'||tcustmer_cust.nextval,'test'||i,'BEIJING','CN');
if mod(i,10)=0 then
commit;
end if;
end loop;
commit;
end;
/
PL/SQL procedure successfully completed.

总结:

对于tcustmer_cust.nextval理解错误,创建序列的目的正是消除主键的干扰,所以在使用的时候需要将其放到列值中。
