    <p>After searching for how to POST large files using python, I came across <a href="https://stackoverflow.com/questions/2502596/python-http-post-a-large-file-with-streaming">this</a> and I wrote a program based on that, but when I run it I get the following error message:</p> <pre><code> Traceback (most recent call last): File "Test3.py", line 187, in &lt;module&gt; main() File "Test3.py", line 184, in main do_upload(options, args) File "Test3.py", line 48, in do_upload response = urllib2.urlopen(request) File "C:\Python27\lib\urllib2.py", line 126, in urlopen return _opener.open(url, data, timeout) File "C:\Python27\lib\urllib2.py", line 400, in open response = meth(req, response) File "C:\Python27\lib\urllib2.py", line 513, in http_response 'http', request, response, code, msg, hdrs) File "C:\Python27\lib\urllib2.py", line 438, in error return self._call_chain(*args) File "C:\Python27\lib\urllib2.py", line 372, in _call_chain result = func(*args) File "C:\Python27\lib\urllib2.py", line 521, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) urllib2.HTTPError: HTTP Error 500: Internal Server Error </code></pre> <p>and here is my code, to run the program I use <code>--upload "path_to_file" [space] "filename"</code>.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
