把这段改成下面的试试：

[QUOTE]Dim Condition
Condition = ""
If Len(bookname)<>0 Then
Condition = Condition & " And bookname like '%"& bookname &"%'"
End If
If booktype<>"不清楚" Then
Condition = Condition & " And booktype='"& booktype &"'"
End If
If Len(publishing)<>0 Then
Condition = Condition & " And publishing like '%"& publishing &"%'"
End If
Sql = "select * from book where bookmoney>="& money1 &" and bookmoney<="& money2 & Condition &" order by bookid desc"[/QUOTE]

最简单的方法Response.write(sql)
看看sql语句是否正确。
如果正确应该怎么办呢?

rs.open sql,conn,1,3
更改为
rs.open ,conn,1,3
因为上一行已经有了．
我刚也遇到过
试下吧
