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;

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:

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。
