Oracle批量操作

racle批量插入：

<insert id="insertBatch" parameterType="java.util.List">
     insert into table_name(id, name,updateTime)
      <foreach collection="list" item="item" index="index" separator="union all" >
       (select
     #{item.id,jdbcType=VARCHAR}, #{item.name,jdbcType=VARCHAR}, #{item.updateTime,jdbcType=TIMESTAMP}
        from dual)
     </foreach>
</insert>

 需要注意的是sql中没有values；<foreach>标签中语句 (select ..... from dual)

 

 

 

oracle批量更新：

<update id="updateBatch" parameterType="java.util.List">
     begin
         <foreach collection="list" item="item" index="index" separator=";" >
             update table_name
             <set>
                 name= #{item.name}
             </set>
             where id = #{item.id}
         </foreach>
         ;end;
</update>

或者 

 

<update id="updateBatch" parameterType="java.util.List">
   <foreach collection="list" item="item" index="index" open="begin" close="end;" separator=";">
      update table_name
      <set>
         name= #{item.name}
      </set>
         where id = #{item.id}
   </foreach>
</update>

 

 

oracle批量删除：

<delete id="deleteBatch" parameterType="java.util.List">
   delete from table_name
   <where>
     <foreach collection="list" index="index" item="item" open="(" separator="or" close=")">
  id=#{item.id}
     </foreach>
   </where>
</delete>
