解决方案 »
- 编写sqlserver存储扩展用c#好还是vb.net好?
- 既然断开无线路由器与internet的连接后,与该路由器连接的各台电脑照样可以作为局域网进行互访,那就不需要建立有线局域网了,也不需要在墙上布线的麻烦了吗?更不需要交换机、集线器等之类的组网设备了,只要一个无线路由器和一些无线网卡即可组建小局域网了。
- 求一SQL
- 关于 Mysql 数据库 升级问题
- 问一个sql统计怎么写?
- 如何改变字段排序规则?

exec proc_paged_2part_selectMax 'qk_jibenxinxi join tb on qk_jibenxinxi.id=tb.id','*',30,1,'id',0,null,'id',0
可能原因:
1.存储过程不一样
2.表不一样:总数据量、数据分布、是否有索引
3.sql版本问题,补丁问题,机器问题
