从Windows本地网络连接到Firebird数据库 [英] Connecting to Firebird database from Windows local network

问题描述

我已经写了一个小型的Python应用程序了几周了.该应用程序从Firebird数据库读取数据，并将其复制到另一个DB.我正在使用内嵌Firebird的FDB.

这是我的连接代码.

I have been writing a small Python app for several weeks. The application reads data from a Firebird database and it copies it to another DB. I'm using FDB with Firebird embedded.

This is my connection code.

def createConnectionTo(path):
    try:
        connection = fdb.connect(
            database=path,
            user='SYSDBA',
            password='masterkey',
            charset='WIN1252'
        )
        print("Connessione al database riuscita!\n")
        return connection
    except fdb.fbcore.DatabaseError as details:
        errorMsg = "ERRORE: impossibile connettersi al database!\nPer favore scegliere un altro file.\n\nDETTAGLI\n"+str(details).replace("\\n", "\n")+"\n"
        print(errorMsg)
        return False
    except fdb.fbcore.ProgrammingError as details:
        errorMsg = "ERROR: bad parameters value!\nPlease check your connection code.\nDETAILS: "+str(details)+"\n"
        print(errorMsg)
        return False
    except Exception as errorMsg:
        print("ERRORE: "+str(errorMsg))
        input("Premi un ENTER per chiudere la finestra.")
        return -1

此代码适用于计算机内部的文件夹，但莫名其妙地不适用于我们本地网络中共享的文件夹.我使用了 os. path.exists()检查Python是否能够找到所选的共享文件夹，并且始终返回True.

我一直收到此错误，而且不知道如何解决它，即使我怀疑这与斜杠转换问题有关.

This code works for folders inside my computer, but inexplicably it doesn't work for folders shared in our local network. I used os.path.exists() to check whetever Python was able to find the selected shared folders and it always returned True.

I keep getting this error and I don't have any clue how to solve it, even if I suspect that it is somewhat related to a slash conversion issue.

('Error while connecting to database:
- SQLCODE: -902
- I/O error during "CreateFile (open)" operation for file "Danea Easyfatt\\ANYMA 2017 dal 06-02-17.eft"
- Error while trying to open file
- Impossibile trovare il percorso specificato. ', -902, 335544344)

我尝试了以下所有方式来键入路径:

I tried all the following way to type the path:

• \\ CENTRALE \ Danea Easyfatt \ ANYMA 2017年6月2日至17日
• //CENTRALE/Danea Easyfatt/ANYMA 2017 dal 06-02-17.eft
• \\\ CENTRALE \\ Danea Easyfatt \\ ANYMA 2017年6月2日至17日.

他们都没有工作.

推荐答案

您无法访问网络共享上的数据库. Firebird明确禁止使用此 ^* .但是，据我所知，显示的错误仅表示您正在尝试使用无效的路径来访问文件.

You cannot access databases on a network share. Firebird explicitly disallows this^*. However, as far as I can tell, the error you display simply means you're trying to use an invalid path to access file.

如果要通过网络连接到Firebird数据库，则应连接到托管该数据库的系统上的Firebird服务器.这意味着要运行Firebird服务器，而不要使用Firebird Embedded.

If you want to connect to a Firebird database over a network, you should connect to a Firebird server on the system hosting the database. That means running Firebird server, not using Firebird Embedded.

^{*:您可以将Firebird配置为允许在网络驱动器上打开数据库，但是如果多个进程试图从不同主机修改数据库，这是破坏数据库的好方法，这是您实际上不应该执行的操作}
