使用ODC文档

使用一个ODC文档可以很轻松在IE浏览器中连接到SQL SERVER数据库的表，ODC文档示例如下：

<html>

<head>

<meta http-equiv=Content-Type content="text/x-ms-odc; charset=utf-8">

<meta name=ProgId content=ODC.Table>

<meta name=SourceType content=OLEDB>

<meta name=Catalog content=K0712>

<meta name=Schema content=dbo>

<meta name=Table content="T_Material">

<xml id=docprops></xml><xml id=msodc><odc:OfficeDataConnection

  xmlns:odc="urn:schemas-microsoft-com:office:odc"

  xmlns="http://www.w3.org/TR/REC-html40">

  <odc:Connection odc:Type="OLEDB">

   <odc:ConnectionString>Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=True;Data Source=develop;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=DEVELOP;Use Encryption for Data=False;Tag with column collation when possible=False;Initial Catalog=K0712</odc:ConnectionString>

   <odc:CommandType>Table</odc:CommandType>

<odc:CommandText>"K0712"."dbo"."ICInventory"</odc:CommandText>

  </odc:Connection>

 </odc:OfficeDataConnection>

</xml>

<style>

<!--

    .ODCDataSource

    {

    behavior: url(dataconn.htc);

    }

-->

</style>

</head>

<body onload=´init()´ scroll=no leftmargin=0 topmargin=0 rightmargin=0 style=´border: 0px´>

<table style=´border: solid 1px threedface; height: 100%; width: 100%´ cellpadding=0 cellspacing=0 width=´100%´>

  <tr>

    <td id=tdName style=´font-family:arial; font-size:medium; padding: 3px; background-color: threedface´>

    </td>

     <td id=tdTableDropdown style=´padding: 3px; background-color: threedface; vertical-align: top; padding-bottom: 3px´>

    </td>

  </tr>

  <tr>

    <td id=tdDesc colspan=´2´ style=´border-bottom: 1px threedshadow solid; font-family: Arial; font-size: 1pt; padding: 2px; background-color: threedface´>

    </td>

  </tr>

  <tr>

    <td colspan=´2´ style=´height: 100%; padding-bottom: 4px; border-top: 1px threedhighlight solid;´>

      <div id=´pt´ style=´height: 100%´ class=´ODCDataSource´></div>

    </td>

  </tr>

</table>

<script language=´javascript´>

function init() {

  var sName, sDescription;

  var i, j;

  try {

    sName = unescape(location.href)

    i = sName.lastIndexOf(".")

    if (i>=0) { sName = sName.substring(1, i); }

    i = sName.lastIndexOf("/")

    if (i>=0) { sName = sName.substring(i+1, sName.length); }

    document.title = sName;

    document.getElementById("tdName").innerText = sName;

    sDescription = document.getElementById("docprops").innerHTML;

    i = sDescription.indexOf("escription>")

    if (i>=0) { j = sDescription.indexOf("escription>", i + 11); }

    if (i>=0 && j >= 0) {

      j = sDescription.lastIndexOf("</", j);

      if (j>=0) {

          sDescription = sDescription.substring(i+11, j);

        if (sDescription != "") {

            document.getElementById("tdDesc").style.fontSize="x-small";

          document.getElementById("tdDesc").innerHTML = sDescription;

          }

        }

      }

    }

  catch(e) {

    }

  }

</script>

</body>

</html>

这样，可以很方便的在Web页面上显示数据表了J

会Web编程的都知道其实是一个HTML文本，采用Javascript来初始化窗口布局，加粗的部分是数据连接的关键部分，如下所示：

<odc:ConnectionString>Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=True;Data Source=develop;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=DEVELOP;Use Encryption for Data=False;Tag with column collation when possible=False;Initial Catalog=K0712</odc:ConnectionString>

   <odc:CommandType>Table</odc:CommandType>

<odc:CommandText>"K0712"."dbo"."ICInventory"</odc:CommandText>

其中，odc:ConnectionString是数据库连接串，使用和ADO一样的格式，不用多说了吧J；odc:CommandType是查询类型，Table是表查询，SQL是标准SQL语句查询；odc:CommandText是查询命令文本，如果是Table类型的，就只要写出表名称就可以了，如master.dbo.sysobjects，如果是SQL类型的话，就是一般的SQL语句，如“SELECT t0.*FROM ICStockBill t0 INNER JOIN ICStockBillEntry t1 ON t0.FStockBillID=t1.FstockBillID ORDER BY t0.FStockBillID”
