通过正常提取:
<%
Set conn= Server.CreateObject("ADODB.Connection")
connstr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="&Server.MapPath("db2.mdb")
conn.Open connstr
Set rs = Server.CreateObject ("ADODB.Recordset")
sql = "Select * from people order by id desc"
rs.Open sql,conn,1,1
Do While Not rs.EOF
Response.write rs("id")&" | "
rs.MoveNext
Loop
%>
耗时3,250.000毫秒，总测试平均值在3秒左右
使用存储过程提取:
<%
Set conn = Server.CreateObject("ADODB.Connection")
Set cmd = Server.CreateObject("ADODB.Command")
conn.Open "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & Server.MapPath("db2.mdb")
cmd.ActiveConnection = conn
cmd.CommandText = "Select * from people order by id desc"
Set rs = cmd.Execute
Do While Not rs.EOF
Response.write rs("id")&" | "
rs.MoveNext
Loop
%>
耗时2,187.500毫秒，总测试平均值在2秒左右
以上两种均不能彻底解决执行时间漫长的问题，主要原因即是循环每次都须向数据库抽取记录(Command速度相对较快)
那么使用GetRows()方法呢:
Set conn = Server.CreateObject("ADODB.Connection")
Set cmd = Server.CreateObject("ADODB.Command")
conn.Open "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & Server.MapPath("db2.mdb")
cmd.ActiveConnection = conn
cmd.CommandText = "Select * from people order by id desc"
Set rs = cmd.Execute
Do While Not rs.EOF
Response.write rs("id")&" | "
rs.MoveNext
Loop
%>
