sql - How to delete completely duplicate rows -

-

Say that there are duplicate rows in my table and well my database design is of third grade: - 

 
  tblProduct (product id, product name, description, category) value (1) Insert 'synthetic', 'cosmetic soap', 'soap'); Enter TblProduct (product, product, name, description, category) values ​​(1, 'synthol', 'cosmetic soap', 'soap'); Enter TblProduct (product, product, name, description, category) values ​​(1, 'synthol', 'cosmetic soap', 'soap'); Insert TblProduct (product, product, name, description, category) values ​​(1, 'Lux', 'cosmetic soap', 'soap'); Insert TblProduct (product, product, name, description, category) values ​​(1, 'Crowning Glory', 'Cosmetic Soap', 'Soap'); Enter TblProduct (product, product, name, description, category) values ​​(2, 'Synthol', 'Good soap', 'Soap'); Insert TblProduct (product, product, name, description, category) values ​​(3, 'Lux', 'good soap', 'soap'); Insert TblProduct (product, product, name, description, category) values ​​(3, 'Lux', 'good soap', 'soap');

I want my table to contain only one instance of each row. Thus, the 2, 3, and the last line whcih should be completely removed as well. Which query can I write for? Can this be done without creating temporary tables? Just in the same question?

Thank you in advance :)

Try it - it's all duplicates from your table Removal of: Duplicate with duplicate (SELECT ProductID, ProductName, Description, Category, ROW_NUMBER), Product from productive product name, from 'RONAMA' Dbo.tblProduct) with duplicate where Roam & Gt; Select 1GO * FROM dbo.tblProduct GO

Your duplicate should now go: Output is: 

  ProductID ProductName DESCRIPTION Category 1 Synthol Cosmetic Soap Soap 1 Lux Cosmetic Soap Soap 1 Crowning Glory Cosmetic Soap Soap 2 Senthol Good Soap Soap 3 Lux Good Soap Soap

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).
