sql - FULL OUTER JOIN or UNION? -

-

How can it be confused or confused with the whole union? I want to be involved in the results like this: 

  Table 1 Table 2 --------------- ---------- --- ---- ID name salary ID return --------------------------------- 1 John 1000 1 Sepals 1 Henry 4000 1 mango 1 smith 1000 1 tomato

should be the result 

  ResultTable ---------------- --- ----- ID name pay fruit ----------------------- 1 John 1000 sepals 1 John 1000 mangoes 1 John 1000 tomato 1 Henry 4000 Sepels 1 Henry 4000 megons 1 Henry 4000 tomato 1 Smith 1000 Sepels 1 Smith 1000 mangoes 1 Smith 1000 Tomatoes  < / Pre>

You need to join a cartesian product or cross-joint. 

 < Table 1 Cross Joyce Tables 2 from Code> SELECT * to Table 1, Table 2

or 

  SELECT *
< P> (context :)

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).
