mybatis针对Oracle数据库进行（单个或多个条件）批量操作（新增、修改、删除）的sql写法--mysql

1、批量新增:
 

     insert into TB_DUTY select SEQ_TB_DUTY.nextval,A.* from(
      
      SELECT  #{item.dscd}, #{item.unitId},#{item.year},#{item.month},#{item.day},#{item.weekDay}, 
      #{item.morningPeopleIds}, #{item.morningPeopleNames},#{item.afternoonPeopleIds},#{item.afternoonPeopleNames},#{item.eveningPeopleIds}, 
      #{item.eveningPeopleNames},#{item.leaderIds},#{item.leaderNames},#{item.flag},#{item.remark},#{item.day0} FROM DUAL
     
    ) A 
  

2、批量修改：
单个条件、单个修改字段：

   
   update tb_code_name_result_new set state=#{state,jdbcType=INTEGER} where id in
      
        #{item}  
      

多个条件、多个修改字段：

   
     
     update TB_DUTY 
     
      
     MORNING_PEOPLE_IDS=#{item.morningPeopleIds,jdbcType=VARCHAR},
      
      
     MORNING_PEOPLE_NAMES=#{item.morningPeopleNames,jdbcType=VARCHAR}, 
       
      
     AFTERNOON_PEOPLE_IDS=#{item.afternoonPeopleIds,jdbcType=VARCHAR},  
      
      
     AFTERNOON_PEOPLE_NAMES=#{item.afternoonPeopleNames,jdbcType=VARCHAR}, 
       
      
     EVENING_PEOPLE_IDS=#{item.eveningPeopleIds,jdbcType=VARCHAR},  
      
      
     EVENING_PEOPLE_NAMES=#{item.eveningPeopleNames,jdbcType=VARCHAR},
      
        
     LEADER_IDS=#{item.leaderIds,jdbcType=VARCHAR},  
      
     
     LEADER_NAMES=#{item.leaderNames,jdbcType=VARCHAR},
     
      
     where DUTY_ID=#{item.dutyId,jdbcType=INTEGER}
    

3、批量删除：
单个条件：

  
     delete from TB_CODE_NAME_RESULT_NEW
    where ID in
       
        #{item}   
      

多个条件：

 
  delete from tb_duty A
  where exists 
  ( 
   select 1 from(
      
     select  B.* from tb_duty B where 1=1 and  B.dscd=${item.dscd} and B.unit_id=${item.unitId} and 
      B.year=${item.year} and B.month=${item.month} and B.flag=${item.flag} 
    
    )S where  A.duty_id=S.duty_id
  )

多个条件第2种形式：

	  
	      
		delete from tb_duty_statistics a 
		where a.person_id 
		in(
		select b.person_id from tb_duty_person_info b where b.dscd=#{dscd,jdbcType=CHAR} and b.unit_id=#{unitId,jdbcType=INTEGER}
		) 
		and substr(a.duty_id,1,7)=#{item.dutyId,jdbcType=CHAR}
		
	

4、批量查询：（未验证）

      
	SELECT  FROM 表名      
	WHERE poi_id in
	
	            
	#{poiId}        
	
	
	AND pass_uid = #{passUid}          
	            
	AND status = #{status,jdbcType=BIGINT}           
	  

5、mapper常用写法

	bb ,
	cc,
