有关ACCESS的SQL语句的用法问题!在线等待

[mark521]

我有个问题想问各位大虾:
我要对一个表里面的数据进行分批读取,而且要从后往前,比如我一个数据表中有100条记录,我要先显示90-100,然后80-89,70-89~~~~~~~~~~~``如何实现呢?

[crystal_heart]

首先要对什么是“先后”进行精确的定义。

[sujiayi]

那你就分批用MovePre来读
10个读一次！

分頁是最好的方法,就象網頁一樣,在DB中也可以這樣

//Display Names and hire dates, five records at a time
pRstEmployees->PageSize = 5;

int intPageCount = pRstEmployees->PageCount;

for(int intPage=1;intPage<=intPageCount;intPage++)
{
pRstEmployees->put_AbsolutePage((enum PositionEnum)intPage);
strMessage = "";

for(int intRecord=1;
intRecord<=pRstEmployees->PageSize;intRecord++)
{

//do something here ...
...

pRstEmployees->MoveNext();

if(pRstEmployees->EndOfFile)
break;
}


}

Actually as smallerkk(smallerkk) said, paging perhaps the best method of all,
u can open the recordset with descending or ascending sort,then specify the pagesize u like

[mark521]

那如何分页呢？不好意思，我对这方面没有什么概念，麻烦说的详细点。最好有原代码哦

???上面不是给代码了
