ADO 预准备 属性


❮ 命令对象完整参考

Prepared 属性设置或返回一个布尔值,如果设置为 True,则表示命令应在执行之前保存 CommandText 属性中指定的查询的预准备版本。

这可能会减慢命令的第一次执行速度,但在第一次执行之后,提供程序将使用已编译的版本,从而导致执行速度更快。


语法

objcommand.Prepared=true 或 false

示例

<%
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.Jet.OLEDB.4.0"
conn.Open "c:/webdata/northwind.mdb"

set comm=Server.CreateObject("ADODB.Command")
comm.ActiveConnection=conn
comm.CommandText="orders"
comm.Prepared=true
response.write(comm.Prepared)

conn.close
%>
