LINQ to SQL – Select with SORT (ORDER BY)

LINQ to SQL – Select with SORT (ORDER BY)

Before writing a LINQ to SQL query, we first need to create a DataContext using the LINQ to SQL Classes template, to know more on how to create the DataContext refer to the post LINQ to SQL Sample

Once the DataContext is created we can query the Object model using LINQ queries, let us consider the Employee table which has the following structure.

In practical situations we will have to SORT Records based on query data for reporting. Assume we have the following data in the Employee Table

Table: Employee

ID	NAME	DOB	DOJ	Phone	Email	DepartmentID	Salery
1	Tom	11/11/1967	05/01/2009	123-123-1234	tom@abcsoftware.com	1	5000
2	Harry	10/07/1973	05/01/2009	123-123-1234	harry@abcsoftware.com	2	6000
3	Peter	12/07/1975	05/01/2009	111-222-3333	peter@abcsoftware.com	3	6500
4	John	05/04/1981	05/01/2009	111-222-3333	john@abcsoftware.com	3	7500
5	Charles	12/12/1973	05/01/2009	666-444-2222	charles@abcsoftware.com	4	6500

Suppose we want to SORT the rows based on Name then in SQL Query we can use the ORDER BY clause as follows

SELECT     ID, Name, Phone

FROM         Employee

ORDER BY Name

Now let us see how the same can be achieved using a LINQ query.

EmployeeClassesDataContext dbContext = new EmployeeClassesDataContext();

var emp = (from e in dbContext.Employees orderby e.Name 

          select new { e.ID, e.Name, e.Phone });
