今天出現一個很奇葩的問題，之前做oracle的批量插入,對於主鍵都是直接在Java中賦值，後來發現不方便，後來改用Sequence.nextval，結果報錯

使用前:

insert into exceltable  (id,chinese,english)
  select 1,'111','111' from dual union all
  select 2,'222','222' from dual

沒有報錯！！！

使用序列後:

insert into exceltable  (id,chinese,english)
  select excel_seq.nextval,'111','111' from dual union all
  select excel_seq.nextval,'222','222' from dual
 

報錯---ORA:02287

先建立函式:

create or replace function get_seq (p_in_sqname in varchar2) return number
is
  l_res number ;
begin
  execute immediate 'select '|| p_in_sqname|| '.nextval from dual' into l_res ;
  return l_res ;
end ;

然後再如下呼叫：

insert into exceltable  (id,chinese,english) 
  select get_seq('excel_seq'),'111','111' from dual union all 
  select get_seq('excel_seq'),'222','222' from dual
