sql - How do you rewrite a query in PostgreSQL 8.3 -

-

I am quite new to SQL and need some help with a certain task. I have a query that is called by our flex / java code which is included in many tables to get the information. After running on the analysis of an explanation, I have seen that the query takes more than 15 minutes, which is sometimes many times if the site is in heavy traffic. What I'm trying to do is to create a rule or trigger, which sees that the query is called and instead selects the data from the physical view table. I tried to apply a rule for this, but when I was having trouble getting errors while trying to join many tables in the rules, there is a way in it, whether it is a rule, a trigger, Or I have not seen anything, to see if a certain query is executed that I can replace that query from another table? Thanks in advance.

Example of the query:

player_id, player_level, select current_location (player_id) from server_info to player_id (location_id) where current_location = 'central Hub '

Why not just convert the app into a source of physical visual What do you want Are you There is no way to rewrite the complex premises for an unrelated table source - which I know and, if you can do this, then really have to do magic in your Query Planner / Rule system? SQL view s is implemented with a SELECT RULE , but it does not get you from complex-query to physical view. You can get it from TABLE1 , TABLE2 .

There will be a better question on what types are player_id , and location_id are both int and Both have btree index? Is current_location indexed, and is it being used for similarity, regeps or conditions of choice? Are you using the version of Postgresql? Can you attach a expanicle analysis to that query, which is why waiting for big time?

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).
