sql - Select DISTINCT items rows and associated columns based on a condition -

-

Suppose i have a table like this in my db 

  date items etc. 7 / 29/2010 3 1 7/30/2010 3 2 7/31/2010 2 3 7/2 9/2010 3 4 7/30/2010 1 5 7/31/2010 1 6 7/29/2010 2 7 7 / 30/2010 3 8 7/31/2010 1 2

For each item type, I want to select the count only on the latest date found in the table.

Is there an easy way to do this?

I'm thinking of something different to get a specific item IDID, but I'm stuck there. 

  to calculate from item id, (select date, item id, calculation, R Rank () (Table by R Rank) (Order IDID, Item IDID, Date Disclosure), where R = 1

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
