Question

我的网络服务器上安装了一些名为phpVMS的软件，我们正在运行名为SmartCARS的软件，它可以跟踪飞行模拟器上的飞机并将数据发送到phpVMS软件。在飞行结束时，PIREP被提交但由于某种原因我得到MySQL语法错误。这是错误：

SELECT * FROM (
    (SELECT c.* FROM sellers c
        LEFT JOIN (
            SELECT * FROM orders
            WHERE order_date BETWEEN DATE(CURDATE() - INTERVAL 2 MONTH) AND NOW()
        ) d ON c.seller_id = d.seller_id
        GROUP BY c.seller_id
        HAVING count(d.order_id) >= 10
    )
    UNION
    (SELECT c.* FROM sellers c 
        LEFT JOIN (
            SELECT * FROM orders WHERE order_date BETWEEN DATE(CURDATE() - INTERVAL 15 DAY) AND NOW()
        ) as d
        ON c.seller_id = d.seller_id
    WHERE d.seller_id IS NULL)
) derived

我还尝试为DateAdd更改NOW（），但是我在错误日志中使用DateAdd替换NOW（）时得到了同样的错误。

任何人都知道如何解决此错误？

这是我能找到的与查询相关的所有代码：

我尝试从代码中删除单引号但我收到此错误

$pirepdata['exported'] = 0;
    $pirepdata['submitdate'] = 'NOW()';
    $pirepdata['modifieddate'] = 'NOW()';
    $pirepdata['accepted'] = PIREP_PENDING;
    $pirepdata['expenselist'] = '0';
    $pirepdata['flighttype'] = $sched->flighttype;

    # Do the insert based on the columns here
    $cols = array();
    $col_values = array();
    foreach ($pirepdata as $key => $value) {
        if($key == 'submitdate') {
            $value = 'NOW()';
        } elseif ($key == 'comment') {
            continue;
        } else {
            $value = "'".DB::escape($value)."'";
        }

        $cols[] = "`{$key}`";        
        $col_values[] = $value;
    }

    $cols = implode(', ', $cols);
    $col_values = implode(', ', $col_values);
    $sql = 'INSERT INTO ' . TABLE_PREFIX . "pireps ({$cols}) VALUES ({$col_values});";

    DB::query($sql);
    $pirepid = DB::$insert_id;

如果我尝试使用php date函数，我会收到此错误

如果按原样运行程序，您会发现$ sql中的值类似于：

function getDriving() {
var url = $('#map').data('request-url2');
$.getJSON(url,
    function (data) {
        var marker = [];

        $.each(data,
            function (i, item) {
                marker.push({
                    'location': new google.maps.LatLng(item.Latitude2, item.Longitude2),
                    'map': map,
                    'weight': item.Speed,
                    'radius': 10
                });
            });
        var pointArray = new google.maps.MVCArray(marker);

        heatmap = new google.maps.visualization.HeatmapLayer({
            data: pointArray
        });
        heatmap.setMap(map);
    });

您会注意到现在（＆＃39; NOW（）＆＃39;引用了修改日期的值。要解决这个问题，您需要做的就是将foreach中的第一张支票更改为：

INSERT INTO wp_pireps (`exported`, `submitdate`, `modifieddate`, `accepted`, `expenselist`, `flighttype`) VALUES ('0', NOW(), 'NOW()', 'PIREP_PENDING', '0', '');

希望这有帮助。
