Hi Francesc, thanks for developing and maintaining PyTables all this years,
good luck to you and good luck to PyTables. I hope that the strengths of
opensource help this project live on.
Armando.

Hi
Here's an alternative method that uses the built-in search capabilities in
PyTables in place of the itertools library.
Using readWhere as shown below will return a NumPy ndarray of the data that
matches the query. I think that answers your question #4. There are
similar methods - where and
Hi All,
Sorry if this sounds too naive.
Wanted to see whether there is a windows installer with the newly created
pytables (with pro) version for both 32 bit and 64 bit operating system.
I did try this location but couldn't find the new version.

Hi Josh,
Thanks for your response. The problem of readWhere() is that it does
not fully take advantage of the fact that my table is sorted and the
time to iterate over it should be no greater than O(n).
The strange thing is that my iter0() is really fast but all other
versions are really slow.
Geoffrey,
I think the difference is that your iter0 function accesses the records in
the order in which they appear in the table, while all the other methods
sort them.
If you only need to read the records associated with a single key at a time,
you could take advantage of the fact that the keys
Is it possible to rename a column in an existing table? I've dug
through the documentation and not been able to find anything.
I'd rather not have to copy the data from the existing table into a
new one, as this will require compacting -- and the database is huge.
Thanks,
Ben
