Built by the engineers behind Netezza and the technology behind Amazon Redshift, AnzoGraph is a native, Massively Parallel Processing (MPP) distributed Graph OLAP (GOLAP) database that executes queries more than 100x faster than other vendors.  

There are times when you want to retrieve the ID of the last inserted record when using Entity Framework. For example:


Employee emp = new Employee();

emp.ID = -1;

emp.Name = "Senthil Kumar B";

emp.Expertise = "ASP.NET MVC"

EmployeeContext context = new EmployeeContext();

context.AddObject(emp);

context.SaveChanges();


In the above example , if i need to retrieve the ID of the employee that was inserted , all that i need to do is use the emp.ID property once the data is saved as shown below.


Employee emp = new Employee();

emp.ID = -1;

emp.Name = "Senthil Kumar B";

emp.Expertise = "ASP.NET MVC"

EmployeeContext context = new EmployeeContext();

context.AddObject(emp);

context.SaveChanges();

int empID = emp.ID;
