Question

我正在尝试在下面的代码中使用mysqli_multi_query函数，但遇到此错误：

命令不同步;你现在不能运行这个命令

// add call stats to incoming nodes
        $sql = "INSERT INTO `" . node_name_formatter($i_route) . "` ";
        $sql .= "            (`timeperiod`, ";
        $sql .= "             `exchange_id`, ";
        $sql .= "             `calls_in`) ";
        $sql .= "VALUES      ('" . date('Y-m-d H:i:s', $time) . "', ";
        $sql .= "             '$exchange_id', ";
        $sql .= "             '1') ";
        $sql .= "ON DUPLICATE KEY UPDATE ";
        $sql .= "             `calls_in` = `calls_in`+1;";

// add call stats to outgoing nodes
        $sql .= "INSERT INTO `" . node_name_formatter($o_route) . "` ";
        $sql .= "            (`timeperiod`, ";
        $sql .= "             `exchange_id`, ";
        $sql .= "             `calls_out`) ";
        $sql .= "VALUES      ('" . date('Y-m-d H:i:s', $time) . "', ";
        $sql .= "             '$exchange_id', ";
        $sql .= "             '1') ";
        $sql .= "ON DUPLICATE KEY UPDATE ";
        $sql .= "             `calls_out` = `calls_out`+1";

       // echo $sql . '<br><br>';
        mysqli_multi_query($connection, $sql) or die(mysqli_error($connection));

我正在按照php manual上的说法进行此查询。使用此函数还是以正常的mysqli_query方式执行2个单独的查询也更好？

更新为

// add call stats to incoming nodes
        $sql = "INSERT INTO `" . node_name_formatter($i_route) . "` ";
        $sql .= "            (`timeperiod`, ";
        $sql .= "             `exchange_id`, ";
        $sql .= "             `calls_in`) ";
        $sql .= "VALUES      ('" . date('Y-m-d H:i:s', $time) . "', ";
        $sql .= "             '$exchange_id', ";
        $sql .= "             '1') ";
        $sql .= "ON DUPLICATE KEY UPDATE ";
        $sql .= "             `calls_in` = `calls_in`+1;";

// add call stats to outgoing nodes
        $sql .= "INSERT INTO `" . node_name_formatter($o_route) . "` ";
        $sql .= "            (`timeperiod`, ";
        $sql .= "             `exchange_id`, ";
        $sql .= "             `calls_out`) ";
        $sql .= "VALUES      ('" . date('Y-m-d H:i:s', $time) . "', ";
        $sql .= "             '$exchange_id', ";
        $sql .= "             '1') ";
        $sql .= "ON DUPLICATE KEY UPDATE ";
        $sql .= "             `calls_out` = `calls_out`+1;";

       // echo $sql . '<br><br>';
        mysqli_multi_query($connection, $sql) or die(mysqli_error($connection));

你必须使用mysqli_next_result遍历结果以获得每个查询的结果。
