使用存儲過程實現分頁打印。www.c hinaitpower.comlhY4v8
這個存儲過程是一個小區寬帶用戶管理系統,項目裡代碼的一部分。www.c hinaitpower.comlhY4v8
功能是:
實現把表userinfo裡的用戶資料按IP網段排序進行分頁打印!!
比如172.20.128.XX的IP簡稱為128網段的用戶,
172.20.119.XX的IP簡稱為119網段的用戶,www.c hinaitpower.comlhY4v8
每個網段的用戶打印在一張A4紙上,
不足一張的按一張打印,其余的可空出。
大於一張小於兩張的按二張打印,其余空出.
經過估算一頁最多只能打印37行.
思路是:先把select出的按IP分組的用戶信息和計算出的空格行insert進一個臨時表中
然後多此臨時表打印就行了。www.c hinaitpower.comlhY4v8
