听朋友说php+sqlserver分页很麻烦，今天研究了一下，发现其实比php+mysql还简单（实际上mysql也可以这样）。
下面这个函数就是取出符合纪录的第$page页的纪录到数组：
function selectPage($QueryStr,$page,$pageSize)
{
$R=@mssql_query($QueryStr);
if ($R){
$totalPage = ceil(mssql_num_rows($R)/$pageSize);
if (!$page ¦ ¦$page<=0) $page=1;
if ($page>$totalPage) $page=$totalPage;
$begin = ( $page-1 ) * $pageSize;
$ReArr=array();
$index=0;
if($pageSize>0) mssql_data_seek($R,$begin);
while($ResultArr=@mssql_fetch_array($R)){
if($pageSize>0)
if($index>$pageSize-1) break;
$ReArr[$index]=$ResultArr;
$index++;
}
return $ReArr;
}else
return false;
}
我觉得这样只用查询一次，用limit还有查询两次。实际上asp就是用这种方式！
欢迎各位提出意见

在MSSQL的mssql_query($string,$int);
其中$string可以是SQL SERVER存储过程的调用.这样就要自己写一个类似于limit的存储过程,在SQL SERVER他虽有TOP这项功能,但它的翻页,我们那时有个写VB的同事封装了一个用游标翻页的存储过程,由于年事以久,且不是自己封装的所一存储过程的代码找不见了,现在说一下调用过程,望能引发大家的一些思维:应该不是误导^_^
$string="exec web_ScrollPage 'fo03t001','complex,description,isroomreqd,isexcludegrp,isautoassign','complex,description,isroomreqd,isexcludegrp,isautoassign',".$PAGE_ROWS.",".$AddValue;
exec web_ScrollPage 'fo03t001',---这一段是掉用存储过程,及所要访问的table
'complex,description,isroomreqd,isexcludegrp,isautoassign',----要读的字段
'complex,description,isroomreqd,isexcludegrp,isautoassign',----存储过程中建立临时表所要的字段
".$PAGE_ROWS.",".$AddValue-----每页的行数,及开始的位置
在存储过程中是先建临时表,移游标到$AddValue所在的位置,然后移动游标一条条将记录读到临时表里,最后再读一次临时,删掉临时表,就这样是不是很烦.
不过在读大量数据是用数组翻页就不如这样了^_^
