Question

我正在我的php代码中执行multi_query并希望在表中回显结果。查询按预期工作并产生所需的输出，但是当我回显数据时，while循环似乎在一次迭代后停止。

以下是我要使用的代码：

if (mysqli_multi_query($db_conx, $sql)) {
do {
    /* store first result set */
    if ($result = mysqli_store_result($db_conx)) {
        while ($row = mysqli_fetch_row($result)) {
            $cur = $row[1];
            $date = $row[7];
            $et = $row[9];
            $result = $row[13];
            $payout = $row[15];
            echo '<tr>
                    <th class="text-center" scope="row">'. $cur .'</th>
                    <td>'. $date .'</td>
                    <td>'. $et .'</td>
                    <td>'. $result .'</td>
                    <td>'. $payout .'</td>
                </tr>';
        }
        mysqli_free_result($result);
    }
} while (mysqli_next_result($db_conx));
}

运行此代码将返回表格的第一行，但之后不再签名。当我测试一些东西时，我注意到如果我只引用其中一行，我能够检索/回显所有内容：

if (mysqli_multi_query($db_conx, $sql)) {
do {
    /* store first result set */
    if ($result = mysqli_store_result($db_conx)) {
        while ($row = mysqli_fetch_row($result)) {
            $cur = $row[1];
            echo $cur;
            echo '<br>';
        }
        mysqli_free_result($result);
    }
} while (mysqli_next_result($db_conx));
}

任何人都可以帮助我吗？我非常感谢你的帮助！

更新：我正在使用的查询（由于测试原因而硬插入的条件值）

SET @row_number_t1:=0;
SET @row_number_t2:=0;

    CREATE TEMPORARY TABLE IF NOT EXISTS t1 AS (
    SELECT cur,date,time_start FROM `cur1` WHERE sig = 5
    );

    INSERT INTO t1
        SELECT cur,date,time_start FROM `cur1` WHERE (sig = 1 OR sig = 2) AND error_code = 0 AND date >= '2016-02-01' AND date <= '2016-02-010'
        UNION SELECT cur,date,time_start FROM `cur2` WHERE (sig = 1 OR sig = 2) AND error_code = 0 AND date >= '2016-02-01' AND date <= '2016-02-010'
    ORDER BY time_start ASC, date;


    SELECT t1_modif.*, t2_modif.* FROM 
        (SELECT @row_number_t1:=@row_number_t1+1 AS row_number1,
            cur,time_start FROM t1) 
            t1_modif
        JOIN (SELECT @row_number_t2:=@row_number_t2+1 AS row_number2,
        trades.* FROM trades WHERE date >= '2016-02-01' AND date <= '2016-02-010'
        ORDER BY startTime ASC, date) 
        t2_modif ON t2_modif.row_number2 = t1_modif.row_number1;

mysqli多查询检索多个结果
