c# - Equivalent of SQL Query with linq -


I search for LINQ equal with this query: 

  Select from shapes I ABS (45.403703 - latitude), ABS (- 71.948638 - longitude)   
 Does anyone have an idea? I started with linq  
 class = "post-text" itemprop = "text">  (45.403703 - X. latitude), Math. Abs (- 71.948638 - X. Long) selection X;

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -
