--------查询重复(不同ORD)

SELECT
 hezi,
 atian,
 gudin,
 
 count(id) AS num
FROM
 gaopinzi
WHERE
 LENGTH(atian) > 0 and   ( del is null    or del=0)  and lang='chinese'
GROUP BY
 hezi,
 atian
 
HAVING
 num > 1

-----------加入临时表.

DELETE from tmp_tsiku;
 
insert tmp_tsiku(hezi,atian,gudin,lang)

SELECT
 hezi,
 atian,
 gudin,
 
 count(id) AS num
FROM
 gaopinzi
WHERE
 LENGTH(atian) > 0 and   ( del is null    or del=0)  and lang='chinese'
GROUP BY
 hezi,
 atian
 
HAVING
 num > 1
;
select *   from tmp_tsiku

去重复存储过程 conf_del
----------------------
原理如下：
for( tmp_tsiku )
if(getTsityao_count(hezi,py))
{
baolyeu_id=  get_top1(hezi,py);
del_other(hezi,py,baolyeu_id);

}

BEGIN
 #Routine body goes here...
declare tmpName varchar(200) default '' ;
declare var_ati varchar(200) default '' ;
  declare havgudin int;
  declare gundi_id int;
  declare rownum int;
  declare tsityao_count int;
  declare baolyeu_id int;

declare tmpint int;
DECLARE isRecordNotFound int;
 
 declare cur1 CURSOR FOR   select hezi,atian from tmp_tsiku where 1=1   ;
declare continue handler for not found set isRecordNotFound = 1;
-- Oracle的PL/SQL的指针有个隐性变量%notfound，
       -- Mysql是通过一个Error handler的声明来进行判断的，
       -- declare continue handler for Not found (do some action);
       -- 在Mysql里当游标遍历溢出时，会出现一个预定义的NOT FOUND的Error，
       -- 我们处理这个Error并定义一个continue的handler就可以了
    -- 下面一句不能没有，否则将会进不了while循环
       set isRecordNotFound = 0;
set rownum=1;
  /*开游标*/
#set tmpName=; set  var_ati
     OPEN cur1;

/*游标向下走一步*/

FETCH cur1 INTO tmpName,var_ati;

/* 循环体 这很明显 把游标查询出的 name 都加起并用 ; 号隔开 */

WHILE ( isRecordNotFound = 0 ) DO

set tsityao_count=getTsityao_count(tmpName,var_ati);
       if tsityao_count>1 THEN
          
          select havgudin,rownum ;
         
             set

baolyeu_id=    get_top1(tmpName,var_ati);

select  gundi_id,rownum ;
             set

tmpint=  del_other(tmpName,var_ati,baolyeu_id);

end if;

set rownum=rownum+1;
/*yao jya jeig select ,beri zweiheu yg result b show chwlai.. */
select 'the end';
      /*游标向下走一步*/

FETCH cur1 INTO tmpName,var_ati;

END WHILE;

CLOSE cur1;

END

-------getTsityao_count---------

END

---------del_other---------

检查得到的tmp是否OK.

触发器日志
---------
以便进行误删除恢复..
CREATE TRIGGER `deladdtime` AFTER UPDATE ON `gaopinzi` FOR EACH ROW begin
 
insert  logx(idop,eventx,timex,demo,hezi,pyold,pynew)values( old.id,'update rec',now(),'',old.hezi,old.atian,new.atian);
end;

删除虫复
-----------
update  gaopinzi set del=1,deltime=now(),dely='del no-gudin'  
where id in (select id from tmp)

----------恢复误删除的记录

select * from logx WHERE id>=6 and id<=10

-----查询是否有重复的记录...

-------得到要保留的ID
SELECT

AND (del IS NULL OR del = 0)
AND lang = 'chinese'
AND hezi = '针'

------删除其他记录.
