Question

我在使用PL / SQL时遇到了一些实际问题。

我编写了一个存储过程，该存储过程准备了XML中的记录并将其插入数据库表中。

对于单个记录输入，它将进行干净地编译。但是我正在寻找一种方法来插入一个大型XML文件的所有记录，并且无法弄清楚如何使外观正确发挥作用。

以下是适用于单个记录输入的代码：

<div class="row bg-dark">
    <div class="col-12 border">
    <canvas id="myChart"></canvas>
    </div>
</div>

<div class="container">
  <div>
    <?php
      $sth = $db->prepare("SELECT Actual FROM csvhoejde1");
      $sth->execute();
      /* Fetch all of the remaining rows in the result set */
      $result = $sth->fetchAll(PDO::FETCH_COLUMN);
      // $result = explode("@", implode(",@", $result));
      // print_r for at se resultaterne.
      echo'<pre>';
      print_r($result);
      echo'</pre>';
      $std = $db->prepare("SELECT Dato_ur_stillet FROM palle_tbs");
      $std->execute();
      /* Fetch all of the remaining rows in the result set */
      $palle = $std->fetchAll(PDO::FETCH_COLUMN);
    ?>
  <div>
</div>
  <!----------------------myChart---------------------->
  <script src="./assets/charts/dist/Chart.js"></script>
<script>



var canvas = document.getElementById("myChart");
var ctx = canvas.getContext("2d");

var horizonalLinePlugin = {
  afterDraw: function(chartInstance) {
    var yScale = chartInstance.scales["y-axis-0"];
    var canvas = chartInstance.chart;
    var ctx = canvas.ctx;
    var index;
    var line;
    var style;

    if (chartInstance.options.horizontalLine) {
      for (index = 0; index < chartInstance.options.horizontalLine.length; index++) {
        line = chartInstance.options.horizontalLine[index];

        if (!line.style) {
          style = "rgba(169,169,169, .6)";
        } else {
          style = line.style;
        }

        if (line.y) {
          yValue = yScale.getPixelForValue(line.y);
        } else {
          yValue = 0;
        }

        ctx.lineWidth = 3;

        if (yValue) {
          ctx.beginPath();
          ctx.moveTo(0, yValue);
          ctx.lineTo(canvas.width, yValue);
          ctx.strokeStyle = style;
          ctx.stroke();
        }

        if (line.text) {
          ctx.fillStyle = style;
          ctx.fillText(line.text, 0, yValue + ctx.lineWidth);
        }
      }
      return;
    };
  }
};
Chart.pluginService.register(horizonalLinePlugin);

var data = {
  labels: [<?php echo join($palle, ',') ?>],
  datasets: [{
    label: "My First dataset",
    fill: false,
    lineTension: 0.1,
    backgroundColor: "rgba(75,192,192,0.4)",
    borderColor: "rgba(75,192,192,1)",
    borderCapStyle: 'butt',
    borderDash: [],
    borderDashOffset: 0.0,
    borderJoinStyle: 'miter',
    pointBorderColor: "rgba(75,192,192,1)",
    pointBackgroundColor: "#fff",
    pointBorderWidth: 1,
    pointHoverRadius: 5,
    pointHoverBackgroundColor: "rgba(75,192,192,1)",
    pointHoverBorderColor: "rgba(220,220,220,1)",
    pointHoverBorderWidth: 2,
    pointRadius: 4,
    pointHitRadius: 10,
    data: [<?php echo join($result, ',') ?>],
  }]
};

var myChart = new Chart(ctx, {
  type: 'line',
  data: data,
  options: {
    "horizontalLine": [{
      "y": 140,
      "style": "rgba(255, 0, 0, .4)",
    }, {
      "y": 120,
      "style": "#00ffff",
    }]
  }
});
</script>

您可以看到我注释掉了我失败的循环尝试。有人可以在这里帮助我，为什么我在XML中循环然后插入不起作用？

谢谢

更新：

我尝试了以下操作-大大简化了XML结构-包括要插入数据库中的两个记录。

单个插入（仅在XML中有记录）可以正常工作，但是只有两个插入失败的插入。

我收到以下错误：

/

但是：

如果您将xml放在文件之间：

<t>
<dortoSalesInputIF>
..
</dortoSalesInputIF>
<dortoSalesInputIF>
..
</dortoSalesInputIF>
<dortoSalesInputIF>
..
</dortoSalesInputIF>
</t>

此代码也将起作用

Answer 2

下面是一个示例，您应该可以对其进行更新以添加到其余列中：

WITH your_xml AS (SELECT 1 id, XMLTYPE('<toplevel><dortoSalesInputIF>
    <order>
        <orderType>DO1</orderType>
        <orderNumber>1304315</orderNumber>
        <customerNumber>5104081</customerNumber>
        <customerOrderReference></customerOrderReference>
        <batchNumber></batchNumber>

这适用于XML文档，其中包含一个“ dortoSalesInputIF”节点以及多个（如我所示）的节点。我还一次性传递了两个XML文档，假定您的XML存储在一个表中（如果是这样，您将用表名替换对“ your_xml”的引用）。

否则，如果将XML作为参数传递，则可以直接在XMLTABLE中直接传递参数-即，您不需要加入，只需执行以下操作：

select * from xmltable(... passing your_xml_parameter columns ...)

一旦有了select语句，就可以在插入语句中使用它，例如：

insert into your_table (col1, col2, ....)
select col1, col2, ...
from   .....

这将比您的过程“获取一行，将数据放入变量，将一行插入表中”要快，因为数据库完成了所有繁重的工作，并且没有在SQL和PL / SQL之间进行上下文切换，并且没有传递数据。

将插入添加到PL / SQL很容易；您只需在开始/结束内对其进行定位，如下所示：

create or replace procedure your_procedure (in_xml xmltype)
is
begin
  insert into your_table (col1, col2, ....)
  select col1, col2, ...
  from   xmltable(... passing in_xml
                  columns ...);
end;
/

（如果这是包中的过程，则不需要create or replace或/。）

使用从XML CLOB读取的PL / SQL将行插入到oracle中
