python读取mdb_什么可以从Python读取Microsoft .MDB文件？
I''m looking for something that can read .MDB files, the format
Microsoft Access uses, from Python. I need to do this on
Linux, without using Microsoft tools. I just need to read
the files once, so I can load the tables into another database.
Speed isn''t an issue, and I don''t need to access the file in
database fashion. The files are too big to read into RAM all at once,
though.
I tried "MDBtools", but the only (last) release was
a pre-release three years ago, and I''ve encountered
many build problems trying to make it work on Fedora
Core 6.

I was just gonna suggest it. Under ubuntu, it works easy as cake, and
converts the mdb nicely to some CSV-files.
I think you should really try and make it work.

What MDBtools did you install? The RPM, a checkout from CVS,
or the downloadable distribution? They''re all different.

I''ve read .MDB files using ODBC. I don''t know how big your files are,
but I had a file with almost 3000 rows and I was able to fetch it in
1-2 seconds. If you want to give it whirl, you just need to create an
ODBC connection and then do the following:
myconn = odbc.odbc(''mydb_connection_name'')
mycursor = myconn.cursor()
mycursor.execute(''SELECT * FROM db_name'')
mydata = mycursor.fetchall()
mycursor.close()
myconn.close()
for each in mydata:
# do something like pull the info from the variable "mydata" and
send it into the other database
It is fast. But you may like what the others have said more.
