c# - Returning related elements in a single query (Is my query bad?) -

-

Hey, I have a table of those products with regards to myself, these table products, their sub-products , And then stores sub-sub-products. When a user searches for the top-most product, this query should be returned to parents, children, and children of his children. Now, my query works, but I am normally new to the structure of the organization and SQL, so I'm not sure that this is a way to do what should be done. To make things a little more hairy, I'm searching for many fields in the table. 

  else {productQuery = solutions in b. Presentation. Example (b.Product.Name == Search || B.Product.Description == Search || B.Product.product 2.Name == Search || B.Product.Product 2.Description ==Search || B Product Product 2. Product 2. Name == Search || B. Product.Product2.Product.Description == Search) Order by B.Product LastNumber Ascending Selection B; }

For clarification, Product 2 is a relationship that goes from child to parent.

Subsection: In the future, I want to search for a child. Return to the parents of my parents, and parents, the way I am currently going to do this Some lambda expressions are to be added and what I did, but raising the relationship is it smart?

There is really nothing wrong with this query. Certainly, the expected access to related members is likely to be in L2E.

Consider using Syntax: 

  b.Product.Name.Equals (Search, String Companion, Ordinal Ignore Case)

Search should usually be case-insensitive

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).
