使用ODC文档在IE中直接连接SQL数据库


  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。
  
  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
