我以前从未使用过 mysqli_multi_query ,这让我感到难以置信,我在网上找到的任何示例都无法帮助我弄清楚我想要做什么。
这是我的代码:
<?php
$link = mysqli_connect("server", "user", "pass", "db");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$agentsquery = "CREATE TEMPORARY TABLE LeaderBoard (
`agent_name` varchar(20) NOT NULL,
`job_number` int(5) NOT NULL,
`job_value` decimal(3,1) NOT NULL,
`points_value` decimal(8,2) NOT NULL
);";
$agentsquery .= "INSERT INTO LeaderBoard (`agent_name`, `job_number`, `job_value`, `points_value`) SELECT agent_name, job_number, job_value, points_value FROM jobs WHERE YEAR(booked_date) = $current_year && WEEKOFYEAR(booked_date) = $weeknum;";
$agentsquery .= "INSERT INTO LeaderBoard (`agent_name`) SELECT DISTINCT agent_name FROM apps WHERE YEAR(booked_date) = $current_year && WEEKOFYEAR(booked_date) = $weeknum;";
$agentsquery .= "SELECT agent_name, SUM(job_value), SUM(points_value) FROM leaderboard GROUP BY agent_name ORDER BY SUM(points_value) DESC";
$i = 0;
$agentsresult = mysqli_multi_query($link, $agentsquery);
while ($row = mysqli_fetch_array($agentsresult)){
$number_of_apps = getAgentAppsWeek($row['agent_name'],$weeknum,$current_year);
$i++;
?>
<tr class="tr<?php echo ($i & 1) ?>">
<td style="font-weight: bold;"><?php echo $row['agent_name'] ?></td>
<td><?php echo $row['SUM(job_value)'] ?></td>
<td><?php echo $row['SUM(points_value)'] ?></td>
<td><?php echo $number_of_apps; ?></td>
</tr>
<?php
}
?>
我要做的就是运行多个查询,然后使用这 4 个查询的最终结果并将它们放入我的表中。
上面的代码根本不起作用,我只是收到以下错误:
警告:mysqli_fetch_array() 期望参数 1 为 mysqli_result,布尔值在 C:\xampp\htdocs\hydroboard\hydro_reporting_2010.php 第 391 行给出
有什么帮助吗?
