sql - Merging result from 2 columns with same name and not over-writing one -

-

मेरे पास एक साधारण MySQL क्वेरी की तरह है: 

  SELECT * content_Category` सीसी से, `Content_item` सीआई जहां CI.content_id = '"। (Int) $ contentId।' 'और CI.category_id = CC.category_id और CI.active = 1

दोनों तालिकाओं में एक कॉलम है कॉन्फ़िगरेशन नामक एक क्वेरी में ओवरराइट हो जाता है अर्थात केवल content_item.configuration परिणाम में लौटा दी गई है। > SELECT CC.configuration को `category_configuration` के रूप में, CC.category_id के रूप में` .....

के रूप में सभी डेटा को चुनने का एक तरीका है * दोनों से और उन डुप्लिकेट को हल करें किसी गैर-विनाशकारी तरीके से स्तंभ नाम।

आपको सभी स्तंभों को अलविदा करने की ज़रूरत नहीं है, केवल एक परस्पर विरोधी: 

  SELECT *, CC.configuration cc_conf, ci.configuration के रूप में ci_conf के रूप में `content_category` सीसी,` content_item` सीआई जहां CI.content_id = '"। (Int) $ contentId।' 'और CI.category_id = सीसी.category_id और CI.active = 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).
