asp问题,关于sql
<!-- #include file=conn.asp --><%
sql="select * from x_"
set rs=conn.execute(sql)
%>
<%do while not rs.eof%>
<%=rs("x_xl")%>
<%x_xl=rs("x_xl")%>
<br>
<%rs.movenext%>
<%
sql="select * from l_ where l_xl='"&x_xl&"'"
set rs=conn.execute(sql)
%>
<%do while not rs.eof %>
<%=rs("l_xb")%>
<br>
<%rs.movenext%>
<%loop%>
<%loop%>
