创建序列: create sequence ccxx_ver_seq start with 1 increment by 1; 创建触发器: create or replace trigger ccxx_ver_tri
创建序列:
create sequence ccxx_ver_seq start with 1 increment by 1;
创建触发器:
create or replace trigger ccxx_ver_trig
before insert on ccxx
for each row begin
select ccxx_ver_seq.nextval into :new.version from dual;
end;
ccxx为触发器应用的表名
version为需要进行值自增长的字段名称
测试:
insert into ccxx(ID,XM,SFZH,XS_SZMD_ID) values('aa','aa','aa','aa');
