Weird FileMaker JDBC Error

Greg Pinero (Primary Searcher) — Wed, 01 Feb 2012 14:29:38 +0000

I was querying a table from FileMaker using DB Visualizer via JDBC/ODBC and I kept seeing error messages like this one:

Error getting value for: 19037/4: com.filemaker.jdbc.FMSQLException: [FileMaker][FileMaker JDBC] For input string: "?": ?

I couldn’t figure out a good way to prevent it, so I looked at the row in the results it was mentioning e.g., 19037, then looked up the corresponding record in FileMaker, and noticed it had “?” instead of numbers in a number field. So I replaced the “?” with 0 and now it seems to work.

Python – How to use MySQLdb when MySQL Isn’t Installed Locally

Greg Pinero (Primary Searcher) — Mon, 21 Nov 2011 14:15:22 +0000

It turns out there’s a new MySQL connection library called MySQL Connector.

I installed it and then I just imported that into my script and everything else seemed to work normally. At least for my simply import script.

import mysql.connector as MySQLdb

I believe this library is designed for those who want to connect to MySQL on another server. It doesn’t seem to require any MySQL libraries to be installed.

When I tried to install mySQLdb it complained with the following message. I’m guessing the problem was that it requires MySQL to be installed:

File "/Users/pinerog/Downloads/MySQL-python-1.2.3/setup_posix.py", line 24, in mysql_config raise EnvironmentError("%s not found" % (mysql_config.path,)) EnvironmentError: mysql_config not found

Python zipfile – Fixing Error: Unable to unarchive “..” into “Downloads”

Greg Pinero (Primary Searcher) — Wed, 19 Oct 2011 12:48:07 +0000

I made a zip file in Python and tried to open it on my mac. I got the error mentioned in the title.

Investigating further, I got this information from running:

lm1:Downloads pinerog$ unzip -t costume_spreadsheets_from_jackrabbit.zip

Archive:  costume_spreadsheets_from_jackrabbit.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of costume_spreadsheets_from_jackrabbit.zip or
        costume_spreadsheets_from_jackrabbit.zip.zip, and cannot find costume_spreadsheets_from_jackrabbit.zip.ZIP, period.

Well, silly me, I forgot to close the zip file I made in Python. Here is the correct code for generating a zip file. Make sure you close the zip file object!

import zipfile
import glob, os

file = zipfile.ZipFile("test.zip", "w")
for name in glob.glob("samples/*"):
    file.write(name, os.path.basename(name), zipfile.ZIP_DEFLATED)
file.close()
