每次通话后关闭连接？

我用2）。但是，您的环境可能会有所不同......在启动连接时，您可能会有更多

或更少的开销，您可能会在调用之间执行* $ *
处理等等


当你对最有效的时候感到好奇 - 找出自己，而不是询问意见。你得到的几乎所有意见肯定会遗漏

你忘记提及的一些变量。

I use 2). However, your environment may be different... you may have more
or less overhead when initiating a connection, you might be doing a *lot* of
processing between calls, etc.

When you''re curious about "most efficient" - find out for yourself, rather
than asking opinions. Almost all opinions you get will certainly leave out
some variable you''ve forgotten to mention.

哪个效率最高点击数据库的方法：1）打开/关闭页面上每次调用数据库的
连接（我们有Subs这样做）/; 2）或使用相同的连接并在结束时关闭它？我感觉
是2更好，但只是想与专家确认。谢谢
提前。

Which is the most efficient way to hit the database: 1) to open/close the
connection for each call to the database on a page (we have Subs that do
this); 2) or use the same connection and close it at the end? My feeling is that 2 is better, but just wanted to confirm with the experts. Thanks in
advance.

谢谢，Aaron。还要感谢有用的链接:)

我通常会在连接时使用。


Sub OpenData（）

''''创建具有全局范围的ado对象

End Sub


Sub CloseData（）

''''''关闭并销毁ado对象

End Sub


OpenData

设置rs1 = adoObject.Execute（无论如何）

'''代码，代码，代码

设置rs2 = adoObject.Execute（whateverElse ）

关闭数据

I''ll typically use on connection.

Sub OpenData()
''''create ado object with global scope
End Sub

Sub CloseData()
''''''closes and destroys ado object
End Sub

OpenData
Set rs1 = adoObject.Execute(whatever)
''''code, code, code
Set rs2 = adoObject.Execute(whateverElse)
CloseData
