• 无分组

  select @rownum:=@rownum+1 as autoSeq,sid,pid,oprimary,seq from singlechoice,(select @rownum:=0) r  order by pid,sid

• 单字段分组

  select (@i := case when @tableName=a.tablename then @i + 1 else 1 end ) as rowIndex,a.*,(@tableName:=a.tablename) from tablestyle a,(select @i:=0,@tableName:='') as t  group by tablename,fieldname  order by tablename,(@i := case when @tableName=a.tablename then @i + 1 else 1 end )

• 多字段分组
