大拿帮忙看看这个语句有问题吗？

create or replace trigger tiaojia

  after insert on bms_entry_pralter_dtl  

  for each row when :NEW.PRICEID=144

begin

    insert into bms_entry_pralter_dtl(ALTERDTLID,ALTERDOCID,PRICEID,GOODSID,fromprice,toprice,zx_saprice) 

    values (bms_entry_pralter_dtl_tmp_.nextval,:NEW.Alterdocid,106,:NEW.Goodsid,:NEW.Fromprice,:NEW.Toprice,:NEW.zx_saprice)

end tiaojia;
