oracle插入时，若表中不存在该信息则插入，否则更新主键外的其他信息

  
--测试数据
create table table1(id varchar2(100),name varchar2(1000),address varchar2(1000));
insert into table1(id,name,address)values('01001','影子','河北') ;
commit;

--插入
merge into table1 t1
using (select '01002' id,'影子' name,'河北' address from dual) t2
on (t1.id = t2.id)
when matched then
     update set t1.name = t2.name, t1.address = t2.address
when not matched then
     insert values (t2.id, t2.name,t2.address);
commit;

--查询结果
select * from table1
01001    影子    河北
01002    影子2    辽宁

--更新
merge into table1 t1
using (select '01001' id,'不是影子' name,'山西' address from dual) t2
on (t1.id = t2.id)
when matched then
     update set t1.name = t2.name, t1.address = t2.address
when not matched then
     insert values (t2.id, t2.name,t2.address);
commit;


--查询结果
select * from table1

01001    不是影子    山西
01002    影子2    辽宁

--删除测试数据
drop table table1;

安全一点的做法

begin
    insert into Table (ID,Value,..) values(1001,'222',...); 
    commit; 
  exception 
    when dup_val_on_idx then 
      update Table set value = '222' where id = 1001;
      commit;
    when others then
      Rollback;
  end;
