sql="select * from address where School like '%"&trim(School)&"%' order by ID asc"
end if
if trim(Name)="" and trim(Tel)<>"" and trim(School)="" then
sql="select * from address where Tel like '%"&trim(Tel)&"%' order by ID asc"
end if
if trim(Name)="" and trim(Tel)<>"" and trim(School)<>"" then
sql="select * from address where Tel like '%"&trim(Tel)&"%' and School like '%"&trim(School)&"%' order by ID asc"
end if
if trim(Name)<>"" and trim(Tel)="" and trim(School)="" then
sql="select * from address where Name like '%"&trim(Name)&"%' order by ID asc"
end if
if trim(Name)<>"" and trim(Tel)="" and trim(School)<>"" then
sql="select * from address where Name like '%"&trim(Name)&"%' and School like '%"&trim(School)&"%' order by ID asc"
end if
if trim(Name)<>"" and trim(Tel)<>"" and trim(School)="" then
sql="select * from address where Name like '%"&trim(Name)&"%' and Tel like '%"&trim(Tel)&"%' order by ID asc"
end if
if trim(Name)<>"" and trim(Tel)<>"" and trim(School)<>"" then
sql="select * from address where Name like '%"&trim(Name)&"%' and Tel like '%"&trim(Tel)&"%' and School like '%"&trim(School)&"%' order by ID asc"
end if
rs.open sql,conn,1,1
'显示搜索结果
if rs.eof and rs.bof then
response.write "目前通讯录中没有记录"
else
do while not rs.eof
response.write "姓名："&rs("Name")&"电话："&rs("Tel")&"学校："&rs("School")&"<br>"
rs.movenext
loop
end if
'断开数据库
set rs=nothing
conn.close
set conn=nothing
%>
理解上述程序时，着重琢磨核心部分，8组语句一一对应了3个搜索框中的8种状态
