小弟初学asp，做了个查询表单，使用三个查询条件，为实现模糊，代码如下：
<%
dim rs3
dim sql3
set rs3=server.createobject( "adodb.recordset ")
sql3 = "select * from ziliao "
rs3.open sql3,MM_conn_STRING,1,1
%>
<%
dim timeid
dim placeid
dim name
timeid=request.QueryString( "timeid ")
palceid=request.QueryString( "placeid ")
name=request.QueryString( "name ")
%>
<%
if trim(timeid)= " " and trim(placeid)= " " and trim(name)= " " then
sql= "select * from ziliao "
end if
if trim(timeid)= " " and trim(placeid)= " " and trim(name) <> " " then
sql= "select * from ziliao where name like '% "&trim(name)& "% ' "
end if
if trim(timeid)= " " and trim(placeid) <> " " and trim(name)= " " then
sql= "select * from ziliao where placeid like '% "&trim(placeid)& "% ' "
end if
if trim(timeid)= " " and trim(placeid) <> " " and trim(name) <> " " then
sql= "select * from ziliao where placeid like '% "&trim(placeid)& "% ' and name like '% "&trim(name)& "% ' "
end if
if trim(timeid) <> " " and trim(placeid)= " " and trim(name)= " " then
sql= "select * from ziliao where timeid like '% "&trim(placeid)& "% ' "
end if
if trim(timeid) <> " " and trim(placeid)= " " and trim(name) <> " " then
sql= "select * from ziliao where timeid like '% "&trim(timeid)& "% ' and name like '% "&trim(name)& "% ' "
end if
if trim(timeid) <> " " and trim(placeid) <> " " and trim(name)= " " then
sql= "select * from ziliao where timeid like '% "&trim(timeid)& "% ' and placeid like '% "&trim(placeid)& "% ' "
end if
if trim(timeid) <> " " and trim(placeid) <> " " and trim(name) <> " " then
sql= "select * from ziliao where timeid like '% "&trim(timeid)& "% ' and placeid like '% "&trim(placeid)& "% ' and name like '% "&trim(name)& "% ' "
