MySQL query, problem with my join? -

-

I'm not sure that there is a problem, but take a look:

I have 3 tables Are:

  • Category: ID, icon, name;
  • Subcategories: ID, Name, Description, Category_ID;
  • Subject: ID, Title, Text, Author, Created, Subcategory_ID;

    • I am now trying to get this information (query): 

      $ string = "select categories.id catid, the categories. In caticon, categories. Catname as name, scatid as subcategories.id, subcategories.name AS scatname, scatdescription as subcategories.description, scatcatid as subcategories.category_id, as COUNT (topics.id) Topics, title AS ttitle, topics. Add sub-sub-categories to the above subclasses from categories classified as Tantric, Subject. ED = 1 sub-disciplines classes Honkaidi = themes. Subcategory_id GROUP BY categories.id ";

    Result: <5 p>

    Perhaps the categories from 5% to 5 - OK, 4 show subcategories only in the first categories.

    Maybe even the question is long? Thanks for any answers.

    this 

      subsection.category_id = 1

    This should be 

      Add sub-categories to sub-categories. Category_id = categories.id

    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).
