Question

oracle用存储过程插入一条数据（用序列实现）

Answer 1

什么意思？其中一个字段是用用序列产生？直接insert into table_a(a,b) values(seq.nextval,sysdate);commit;

Answer 2

首先创建一个序列
create sequence seq1
increment by 1
start with 1
maxvalue 999999999;

测试表
create table a
(
a number(20),
b varchar2(10)
);
其次创建存储
create or replace procedure pro_insert
(a_p in varchar2)
is
begin
insert into a
(a,b)
values
(seq1.nextval,a_p); ---seq1.nextval是表示已经有的序列上加1
commit;
end pro_insert;

插入数据
SQL> set serveroutput on;
SQL> execut pro_insert('a');

PL/SQL procedure successfully completed

SQL> select * from a;

A B
