Oracle 存储过程例子
综合性例子：

create or replace procedure CutPrice is
vChar varchar2(50);
begin

  select author into vChar from articleinfo where id =1294412460658;

  For BSI in (
      select id,substr(author,instr(author,vChar)) as unit, 
      nvl(substr(author,0,instr(author,vChar)-1),0) price,
      nvl(substr(QUOTE,0,instr(QUOTE,vChar)-1),0) price360 
      from articleinfo  
      where id not in (
            select id from articleinfo ai where (ai.author not like '%'||vChar||'%') or (ai.QUOTE not like '%'||vChar||'%') and INFOID='360product'
      ) and INFOID='360product' and INSTR(author,'.')!=0 and INSTR(QUOTE,'.')!=0
  )
  loop
      begin
        update articleinfo set updatedate=sysdate,unit = BSI.Unit,price = BSI.Price,price360 = BSI.Price360,author = '',quote = '' where id = BSI.Id;
      exception WHEN OTHERS THEN
         insert into errorLog values(BSI.ID);
      end;
  end loop;
end CutPrice;

调用：

declare
begin
CutPrice();
end;
