取n到m条记录.txt

SQL语句集锦,很多精彩的语句,希望深入SQL的朋友可以研究一下.

 1.   
  select   top   m   *   from   tablename   where   id   not   in   (select   top   n   *   from   tablename)   
    
  2.   
  select   top   m   *   into   临时表(或表变量)   from   tablename   order   by   columnname   --   将top   m笔插入   
  set   rowcount   n   
  select   *   from   表变量   order   by   columnname   desc   
    
  3.   
  select   top   n   *   from     
  (select   top   m   *   from   tablename   order   by   columnname)   a   
  order   by   columnname   desc   
    
    
  4.如果tablename里没有其他identity列，那么：   
  select   identity(int)   id0,*   into   #temp   from   tablename   
    
  取n到m条的语句为：   
  select   *   from   #temp   where   id0   >=n   and   id0   <=   m   
    
  如果你在执行select   identity(int)   id0,*   into   #temp   from   tablename这条语句的时候报错,那是因为你的DB中间的select   into/bulkcopy属性没有打开要先执行：   
  exec   sp_dboption   你的DB名字,'select   into/bulkcopy',true   
    
    
  5.如果表里有identity属性，那么简单：   
  select   *   from   tablename   where   identitycol   between   n   and   m
