mysql - Problem with writing an SQL Sub Query -

-

I know that I should be missing something simple ... but I'm having trouble writing a SQL sub query . Looking at the following data 

  user_id question_id ANSWER_TEXT 89 1 value 1 89 2 value 2 80 2 value 2 99 2 value 2 96 1 value 1 96 2 value 2 111 1 value 1 111 2 value 2  
 <
 
  p> I have both question_id of user_id1 = 'VALUE1' and 2 = 'value2'  
 above the results The query is generating the question_id that needs to be received> User_answer`.user_id`, `User_answer`.question_id`,` User_ant`.`answer_text` Selection` `` user_answers` User_answer` where` User_answer`. In question_id` (1, 2) and `User_answer` in ('value1', 'value2') .`_txt`  
 
 but of course it Land that "value 1" but has a fully answer the question with a question with different answers 2 than 1 return value "2" (and vice versa). 
 
 I need to add in more circumstances but I think I can add that if I can at least do these two things.

One way to use self join is to use eg 

 Select  as a1.user_id, ANSWER1, a2.answer_text as a1.answer_text user_answers as a1 a1.userid = a2.userid and a1.question_id = 1 and a2 as ANSWER2. Question_id = 2 where A1.answer_text to join user_answers a2

Sorry if the syntax is a bit far away (it's been a while since I was using MySQL), but you get this idea.

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).
