MYSQL网页设计sqlserver 存储历程分页代码第1/2页

根据Evans的调查报告，“MySQL的使用在未来将继续呈成长趋势。”复制代码代码以下:
declare@TotalCountint
declare@TotalPageCountint
execP_viewPage_Atype1,*,id,,idasc,1,0,4,3,@TotalCountoutput,@TotalPageCountoutput

@TableNameVARCHAR(200),--表名
@FieldListVARCHAR(2000),--显现列名，假如是全体字段则为*
@PrimaryKeyVARCHAR(100),--单一主键或独一值键
@WhereVARCHAR(2000),--查询前提不含where字符，如id>10andlen(userid)>9
@OrderVARCHAR(1000),--排序不含orderby字符，如idasc,useriddesc，必需指定asc或desc
--注重当@SortType=3时失效，记着必定要在最初加上主键，不然会让你对照忧郁
@SortTypeINT,--排序划定规矩1:正序asc2:倒序desc3:多列排序办法
@RecorderCountINT,--纪录总数0:会前往总纪录
@PageSizeINT,--每页输入的纪录数
@PageIndexINT,--以后页数
@TotalCountINTOUTPUT,--记前往总纪录
@TotalPageCountINTOUTPUT--前往总页数

怎样用vc#挪用下面的存储历程

由于在MySQL中有如此众多的额外功能可选，诸如存储引擎等，你可以选择最适合你公司的一个，或者尝试选用多个引擎。MySQL开始非常小巧，但是可以随着公司的成长而不断地变强大。

而写到本地,我又考虑到效率问题.大家来讨论讨论吧,分数不打紧,就给10分,十全十美,没啥对错,各抒己见,但是要有说服力的哦~

还不是性能有问题！否则面向对象的数据库早就实现了！建议使用CLR的地方一般是和应用的复杂程度或操作系统环境有很高的耦合度的场景。如你想构建复杂的算法，并且用到了大量的指针和高级数据模型。

可以动态传入参数，省却了动态SQL的拼写。

总感觉自己还是不会SQL

换言之，只有在不断的失败中尝试成功，而关于失败的总结却是很少的

无法深入到数据库系统层面去了解和探究

而SQLServer如果能像Oracle一样可以为登陆分配如：5%的cpu，10%的内存。就可以解决这个漏洞。

从项目平台的选择上讲，我们关心的，应该是一款产品能不能满足任务需求，而不是网上怎么说。
