• 不断与Excel连接和脱离Mysql
原标题:Connecting and disconnecting from Mysql continuously with Excel

Newbie question...sorry

I have a simple mysql database running in our Intranet (windows server) which >20 people connect to for searching/inserting records, etc This is done with a simple Excel GUI.

过程是:

  • Search Strings are typed in excel cells
  • VBA opens connection to Mysql and query is run
  • Results retrieved are put on excel Connection to
  • mysql closed with VBA

The above process takes in general 0-2 seconds. Records retrieved <100. Everthing runs fine so far.

In order to be able to connect more people in future, I would like to have some feedback on whether it is ok to continously connect and disconnect from mysql in the way I am doing. Can it cause some type of crash/memory leaks, etc ??

是否有更好的办法这样做?

I am hoping to get <2000 users, but I understand the more users connected, worse it is. By disconnecting after each search/insert, I am hoping to keep the number of live connections as low as possible.

感谢您的投入

这种持续的连接和脱节是一个昂贵的过程。

更好的办法是使用服务器边的文字来管理您的联系。 这样,你就能够与每个服务器保持一个单一的持续联系,用户将通过单一链接进行查询。 你们还需要执行某种执行职务。
