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”
