需要使用 PDO 获取 MSSQL table 在 PHP 中一次显示 25 条记录

Question

我正在尝试让 MSSQL table 限制显示 25 条记录，然后其余的在底部显示一个数字，表示 1 到它结束的任何数字，并且能够点击每个数字显示 100 条记录。

Answer 1

使用 LIMIT 函数将您的查询限制为一个子集。来自 MySQL 文档 (https://dev.mysql.com/doc/refman/5.1/en/select.html)：

SELECT * FROM tbl LIMIT 5,10;  # Retrieve rows 6-15

您需要做的就是确定偏移量和分页大小：

$num_per_page = 25;
// Get this from the user (and default to 1 as the first page)
$page = (int)$_GET['page'] ? (int)$_GET['page'] : 1;

$stmt = $db->prepare("SELECT * FROM receivingrequests WHERE status='Completed' Limit :offset,:limit");
$stmt->execute(array(':offset' => int($num_per_page * ($page-1)), ':limit' => $num_per_page));

Answer 2

使用 $_get（或 $_post）获取当前页面并限制查询例如限制 (($id-1)*25,($id-1)*25+25) $id=1 会显示 1,25
