Paging oracle database implementation_PHP tutorial

This article will introduce the paging function of the database implemented by PHP and orace database. Students in need can take a look below.

The code is as follows

 代码如下

复制代码

include "/maya/inc/dbconn.php";
$sql="select max(rownum) from xqhtest where id<50";
$stmt=ociparse($gConn,$sql);
ociexecute($stmt);
ocifetch($stmt);
$rowcount=ociresult($stmt,1);
ocifreestatement($stmt);
echo("共有".$rowcount."条记录
n");
$recordperpage=15; //每页显示多少条记录
$pages=ceil($rowcount/$recordperpage);  //总页数
echo("共有".$pages."页
n");

?>

//判断偏移量参数是否传递给了脚本，如果没有就使用默认值0

if (empty($offset))
{
    $offset=1;
}
$currentpage=ceil($offset/$recordperpage); //显示当前页
echo("当前页:".$currentpage."
n");
$endset=$offset+$recordperpage;

$stmt2=ociparse($gConn,"SELECT rownum,id,name FROM xqhtest WHERE id<50 and rownum<".$endset." minus select rownum,id,name from xqhtest where id<50 and rownum<".$offset);
//echo "SELECT id,name FROM xqhtest WHERE rownum<".$endset." minus select id,name from xqhtest where rownum<".$offset."
n";
ociexecute($stmt2);
//可以是任何sql语句,但select后面一定要有rownum,这是oracle特有的!
while (ocifetch($stmt2))

{
echo("

n");

   //换成你用于显示返回记录的代码
}
//要写出到所有页面的链接
print "

id	name
".ociresult($stmt2,"ID")."	".ociresult($stmt2,"NAME")."

";

for ($i=1; $i <= $pages; $i++)
{
$newoffset=($recordperpage*($i-1))+1;
print "$i n";
}
print "
";

$nextoffset=$recordperpage*$currentpage+1;
$prevoffset=$recordperpage*($currentpage-2)+1;
//判断是否需要上一页连接
if (($currentpage>1) && ($currentpage<=$pages))
{
print "上一页 n";
}

Copy code

n");
$recordperpage=15; //How many records are displayed on each page
$pages=ceil($rowcount/$recordperpage); //Total number of pages
echo("Total".$pages."Page
n");

?>

//Determine whether the offset parameter is passed to the script, if not, use the default value 0 if (empty($offset))
{
$offset=1;
}
$currentpage=ceil($offset/$recordperpage); //Display the current page
echo("Current page:".$currentpage."
n");
$endset=$offset+$recordperpage; $stmt2=ociparse($gConn,"SELECT rownum,id,name FROM xqhtest WHERE id<50 and rownum<".$endset." minus select rownum,id,name from xqhtest where id<50 and rownum<" .$offset);
//echo "SELECT id,name FROM xqhtest WHERE rownum<".$endset." minus select id,name from xqhtest where rownum<".$offset."
n";
ociexecute($stmt2);
//It can be any SQL statement, but there must be rownum after select, which is unique to Oracle!
while (ocifetch($stmt2)) {
echo("

id	name
".ociresult($stmt2,"ID")."	".ociresult($stmt2,"NAME")."n"); //Replace with the code you use to display the returned records } //To write links to all pages print "

";
for ($i=1; $i <= $pages; $i++)
{
$newoffset=($recordperpage*($i-1))+1;
print "$i n";
}
print "
