SQL 属性范例

以下代码说明如何在设计时设置 RDS.DataControl 参数并使用随 SQL Server 6.5 带来的称为 Pubs 的 ODBC 数据源将其绑定在数据识别控件上。

<!—- RDS.DataControl -- >
<OBJECT classid="clsid:BD96C556-65A3-11D0-983A-00C04FC29E33" ID=ADC HEIGHT=10 WIDTH=10>
   <PARAM NAME="SQL" VALUE="Select * from Authors">
   <PARAM NAME="SERVER" VALUE="http://MyWebServer">
<PARAM NAME="CONNECT" VALUE="dsn=pubs;UID=sa;PWD=;">
</OBJECT><!-- 数据网格 -- >
<Object CLASSID="clsid:AC05DC80-7DF1-11d0-839E-00A024A94B3A"
   CODEBASE="http://MyWebServer
/MSADC/Samples/Sheridan.cab"
   ID=GRID1 
      datasrc=#ADC 
      HEIGHT=125 
      WIDTH=495>
   <PARAM NAME="AllowAddNew" VALUE="TRUE">
   <PARAM NAME="AllowDelete" VALUE="TRUE">
   <PARAM NAME="AllowUpdate" VALUE="TRUE">
   <PARAM NAME="BackColor"   VALUE="-2147483643">
   <PARAM NAME="BackColorOdd"  VALUE="-2147483643">
   <PARAM NAME="ForeColorEven" VALUE="0">
</OBJECT>

以下的范例说明如何在运行时设置 RDS.DataControl 所必需的参数。要测试该范例，请剪切该代码到标准 HTML 文档的 <Body></Body> 标记之间，然后将其命名为 “ADCapi5.asp”。ASP 脚本将标识服务器。
