How to do Select All(*) in linq to sql

Question

How do you select all rows when doing linq to sql?

Select * From TableA

In both query syntax and method syntax please.

Answer 1

Assuming TableA as an entity of table TableA, and TableADBEntities as DB Entity class,

1. LINQ Method

IQueryable result;
using (var context = new TableADBEntities())
{
   result = context.TableA.Select(s => s);
}

2. LINQ-to-SQL Query

IQueryable result;
using (var context = new TableADBEntities())
{
   var qry = from s in context.TableA
               select s;
   result = qry.Select(s => s);
}

Native SQL can also be used as:

3. Native SQL

IList resultList;
using (var context = new TableADBEntities())
{
   resultList = context.TableA.SqlQuery("Select * from dbo.TableA").ToList();
}

Note: dbo is a default schema owner in SQL Server. One can construct a SQL SELECT query as per the database in the context.
