我们可以使用 SQL 创建查询来仅指定要查看的记录(和字段)的选择。
在这里,我们只想显示 "Customers" 表中具有以 "A" 开头的 "Companyname" 的记录(请记住使用 .html 扩展名保存文件):
<html>
<body>
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "c:/webdata/northwind.mdb"
set rs=Server.CreateObject("ADODB.recordset")
sql="SELECT Companyname, Contactname FROM Customers WHERE CompanyName LIKE 'A%'"
rs.Open sql, conn
%>
<table border="1" width="100%">
<tr>
<%for each x in rs.Fields
response.write("<th>" & x.name & "</th>")
next%>
</tr>
<%do until rs.EOF%>
<tr>
<%for each x in rs.Fields%>
<td><%Response.Write(x.value)%></td>
<%next
rs.MoveNext%>
</tr>
<%loop
rs.close
conn.close%>
</table>
</body>
</html>
这里我们只想显示来自西班牙的客户(记住使用 .html 扩展名保存文件):
<html>
<body>
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "c:/webdata/northwind.mdb"
set rs=Server.CreateObject("ADODB.recordset")
sql="SELECT Companyname, Contactname FROM Customers WHERE Country='Spain'"
rs.Open sql, conn
%>
<table border="1" width="100%">
<tr>
<%for each x in rs.Fields
response.write("<th>" & x.name & "</th>")
next%>
</tr>
<%do until rs.EOF%>
<tr>
<%for each x in rs.Fields%>
<td><%Response.Write(x.value)%> </td>
<%next
rs.MoveNext%>
</tr>
<%loop
rs.close
conn.close
%>
</table>
</body>
</html>
在这里,我们要创建一个过滤器,并让用户选择要显示来自哪个国家/地区的客户(请记住使用 .html 扩展名保存文件):
<html>
<body>
<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "c:/webdata/northwind.mdb"
set rs=Server.CreateObject("ADODB.recordset")
sql="SELECT DISTINCT Country FROM Customers ORDER BY Country"
rs.Open sql, conn
country=request.form("country")
%>
<form method="post">
Choose Country <select name="country">
<% do until rs.EOF
response.write("<option")
if rs.fields("country")=country then
response.write(" selected")
end if
response.write(">")
response.write(rs.fields("Country"))
rs.MoveNext
loop
rs.Close
set rs=Nothing %>
</select>
<input type="submit" value="Show customers">
</form>
<%
if country<>"" then
sql="SELECT Companyname,Contactname,Country FROM Customers WHERE country='" & country & "'"
set rs=Server.CreateObject("ADODB.Recordset")
rs.Open sql,conn
%>
<table width="100%" cellspacing="0" cellpadding="2" border="1">
<tr>
<th>Companyname</th>
<th>Contactname</th>
<th>Country</th>
</tr>
<%
do until rs.EOF
response.write("<tr>")
response.write("<td>" & rs.fields("companyname") & "</td>")
response.write("<td>" & rs.fields("contactname") & "</td>")
response.write("<td>" & rs.fields("country") & "</td>")
response.write("</tr>")
rs.MoveNext
loop
rs.close
conn.Close
set rs=Nothing
set conn=Nothing%>
</table>
<% end if %>
</body>
</html>
