这是我的代码:
<table width=600 Border=1 cellspacing=0 cellpadding=3>
<tr>
<td bgcolor = Blue><center><font Color = WHITE size ="2"><B>NUMBER</B></font></center></td>
<td bgcolor = Blue><center><font Color = WHITE size ="2"><B>NAME</B></font></center></td>
<td bgcolor = Blue><center><font Color = WHITE size ="2"><B>FS Tax</B></font></center></td>
<td bgcolor = Blue><center><font Color = WHITE size ="2"><B>Beer Tax</B></font></center></td>
</tr>
<%
'Open the recordset object executing the SQL statement and return records
Recordset.Open SQL,Connection
'first of all determine whether there are any records
If Recordset.EOF Then
Response.Write("No records returned.")
Else
'if there are records then loop through the fields
Do While NOT Recordset.Eof
Response.write "<tr>"
Response.write "<td>" & Recordset("Number") & "</td>"
Response.write "<td>" & Recordset("Location_Name") & "</td>"
If IsNull(FS_Tax) Then
Response.write "<td>" & "None" & "</td>"
End If
Response.write "<td>" & Recordset("FS_Tax") & "%" & "</td>"
Response.write "<td>" & Recordset("Beer_Tax") & "%" & "</td>"
Response.write "</tr>"
Recordset.MoveNext
Loop
End If
%>
</table>
该表忽略了“If IsNull(FS_Tax)”语句。有什么想法吗?
我希望它将表中的值更改为“None”,而不是仅显示NULL值的“%”。

正如@Fabio所提到的,FS_Tax
不是变量。如果它是表格中的列,则需要使用Recordset("FS_Tax")
来检索其值。
此外,您可以在原始SQL语句中考虑NULL,而不必在VBScript中处理它:
select isnull(FS_Tax,'None')[FS_Tax] from ...
当您从记录集中读取它时,这将确保FS_Tax
永远不会为空。

未声明变量 FS_Tax 。也许你的意思是数据库领域?如果是这样,请尝试以下操作:
If IsNull(Recordset("FS_Tax")) Then
