Question

PHP

我在这里有一个问题。我正在使用以下查询。我正在使用循环运行此查询？

如何在没有循环的情况下运行此查询？

我不想在foreach中运行查询？我怎么能这样做？

我使用正确的方法来运行此查询吗？

加载需要时间。是否有任何优化来实现这一目标？

我需要执行多个查询才能一次运行它们吗？

<?php
    $year = "2016";
    $start    = new DateTime($year.'-01-01');
    $start->modify('first day of this month');
    $end      = new DateTime($year.'-12-31');
    $end->modify('first day of next month');
    $interval = DateInterval::createFromDateString('1 month');
    $period   = new DatePeriod($start, $interval, $end);

    foreach ($period as $dt) {

       $calcstart_date = $dt->format("Y-m-d").' 00:00:00';
       $calcend_date  = $dt->format("Y-m-t").' 11:59:00';
       $month_name  = $dt->format('M');

       $test_submitted_query = db_query("
            SELECT requester_id, email, username, is_dashboard_user, SUBMITTED_ON 
            FROM testing_a, aspusers a 
            WHERE requester_id=a.user_id 
            AND AD_MAIL_ATTRIBUTE IS NOT NULL 
            AND IS_DASHBOARD_USER = 'y' 
            AND  SUBMITTED_ON >= timestamp '$calcstart_date' 
            AND SUBMITTED_ON <= timestamp '$calcend_date' 
       ");

    }
?>

php部分不是nessesary，你可以使用mysql的date and time functions。

实施例

# The default backend; one of GTK GTKAgg GTKCairo GTK3Agg GTK3Cairo
# MacOSX Qt4Agg Qt5Agg TkAgg WX WXAgg Agg Cairo GDK PS PDF SVG
# Template.
# You can also deploy your own backend outside of matplotlib by
# referring to the module name (which must be in the PYTHONPATH) as
# 'module://my_backend'.
backend      : qt5agg

你应该得到12行的结果
