Undocumented SQL Server 2012 Express LocalDB

As a developer of Microsoft Visual Studio, SQL Server 2012 Express LocalDB probably has gotten onto your machine without your notice. I will document some of my exploration on LocalDB in this post.

Installation and Location

There are three ways to get LocalDB onto your machines:

  1. Install together when installing Microsoft Visual Studio 2013 (this is my case);
  2. Install by using SqlLocalDB.msi found in SQL Server 2012 Express
  3. Install by downloading from Microsoft Download Centre directly (here).

The installation location is default to C:\Program Files\Microsoft SQL Server\110\LocalDB\Binn where sqlserv.exe is the main application.

The tools (utilities) to operate the LocalDB are SqlLocalDB, SQLCMD and bcp which are located at C:\Program Files\Microsoft SQL Server\110\Tools\Binn. Make sure to include it into your PATH.

SqlLocalDB

This is the utility to administrate the localdb instances.

  • to get help: sqllocaldb -?
  • to print the version: sqllocaldb versions
  • to create an instance: sqllocaldb create “YourInstanceName”
  • to delete an instance: sqllocaldb delete “YourInstanceName”
  • to start an instance: sqllocaldb start “YourInstanceName”
  • to stop an instance: sqllocaldb stop “YourInstanceName”
  • to share an instance: sqllocaldb share “YourInstanceName”
  • to unshared an instance: sqllocadbl unshare “YourInstanceName”
  • to list all your instances: sqllocaldb info
  • to list the status of an instance: sqllocaldb info “YourInstanceName”
  • to set the trace on and off: sqllocaldb trace on|off

If you’ve used VS 2013 to connect to LocalDB, VS 2013 would have created an instance for you (in my case is v11.0).

Even your instance is stopped, it will be auto-started when you try to connect to it first time either via VS 2013 or SQLCMD.

SQLCMD, BCP, process ‘sqlservr’

Both SQLCMD and BCP are well documented. The only difference between LocalDB and SQL server is that we need to put a bracket ‘()’ to indicate it is a LocalDB instead of hostname for the named instance like:

sqlcmd -S ‘(LocalDB)\v11.0’

This is also applied to SSMS and VS 2013 connections. There is only one process “sqlservr” related to LocalDB. It is very lightweighted by using about 12MB RAM on my machine.

Some Examples

Sharing or Not

From A TechNet Article
When sharing a SqlLocalDB instance with a non-owner, you must re-start the instance for the other users to be able to see the instance you have shared. A non-owner cannot start an instance, so if you are going to share an instance with other users who can access your machine, you also need to be sure it has been started. When you create an instance you can do this as follows:

sqllocaldb create “MyInstance”
sqllocaldb share “MyInstance” “OurInstance”
sqllocaldb start “MyInstance”

You should add users explicitly when connected to the instance as the owner, e.g.

CREATE LOGIN [Domain\User] FROM WINDOWS;
GRANT CONNECT TO [Domain\User];
— other permissions…

In general, though, the purpose of SqlLocalDB is to serve as a sandbox for an individual developer on a machine, not to serve as a development environment for multiple users. Each user should be able to create, start, administer and use his/her own LocalDB instances.

Using Entity Framework in an ASP.NET MVC5 Application

In my previous two posts, I built a C# console application using Entity Framework (EF) in Microsoft Visual Studio 2013, and investigated how to perform CRUD operations on EF.

Building an ASP.NET MVC5 application using EF can become a straightforward job in Visual Studio 2013. It is very similar to building a J2EE MVC application by using JPA in Netbeans 7. The steps can be summarized as three steps: 1) create a ASP.NET MVC project; 2) add M: reversed engineer an EF model(M) from database; 3) Add C with V: scaffolding MVC 5 Controller (C) with views (V) using EF.

1. Create a ASP.NET MVC Project

In Microsoft Visual Studio 2013, create a new project (Ctrl-Shift-N) called EmployeeMVC using template (Visual C#->ASP.NET Web Application) and also select a template ‘MVC‘ and add folders and core references for ‘MVC’.

What will happene?
Visual Studio will create a few folders (App_Data, App_Start, Content, Controllers, fonts, Models, Scripts, Views) and files (Global.asax, packages.config, Web.config, Project_Readme.html, Startup.cs), also download a list of js scripts in Scripts folder, create AccountViewModels.cs and IdentityModels.cs in Models folder, AccountController.cs and HomeController.cs in Controllers folder, a list of *.shtml in various view folders, site style sheets in Contents folder and a few config.cs in App_Start.

Press F5 to build and run the empty application now.

2. Add ADO.NET Entity Data Model

Following the steps to reversed engineer EF 5 model from a table in the database into ASP.NET MVC (for reversed engineer an EF 6 model class, please use Entity Framework Power Tools):

  • Right click on Models folder, and choose New Item-Add->Data->ADO.NET Entity Data Model (C#);
  • Provide a Name: EmployeeModel.edmx and Click ‘Add’;
  • Choose ‘generate from database’ and Click ‘Next’
  • Connect to a SQL instance (local), choose your database (test) and table (HR.Employee)
  • If you receive a security warning, select OK to continue running the template.
  • This will add EmployeeModel.edmx (EF 5) as a folder under Models, and also add relevant references.

    Build the solution.

    3. Generate Controller and Views

    To generate controller and views:

  • Add the new controller to the existing Controllers folder. Right-click the Controllers folder, and select Add – New Scaffolded Item; Select the MVC 5 Controller with views, using Entity Framework option. This option will generate the controller and views for updating, deleting, creating and displaying the data in your model.
  • Set the controller name to EmployeeController, select Employee (EmployeeMVC.Models) for the model class, and select the testEntities (EmployeeMVC.Models) for the context class, Click ‘Add’
  • This will create EmployeeController.cs in Controllers:

    using System;
    using System.Collections.Generic;
    using System.Data;
    using System.Data.Entity;
    using System.Linq;
    using System.Net;
    using System.Web;
    using System.Web.Mvc;
    using EmployeeMVC.Models;
    
    namespace EmployeeMVC.Controllers
    {
        public class EmployeeController : Controller
        {
            private testEntities db = new testEntities();
    
            // GET: /Employee/
            public ActionResult Index()
            {
                var employees = db.Employees.Include(e => e.Employee1);
                return View(employees.ToList());
            }
    
            // GET: /Employee/Details/5
            public ActionResult Details(int? id)
            {
                if (id == null)
                {
                    return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
                }
                Employee employee = db.Employees.Find(id);
                if (employee == null)
                {
                    return HttpNotFound();
                }
                return View(employee);
            }
    
            // GET: /Employee/Create
            public ActionResult Create()
            {
                ViewBag.mgrid = new SelectList(db.Employees, "empid", "lastname");
                return View();
            }
    
            // POST: /Employee/Create
            // To protect from overposting attacks, please enable the specific properties you want to bind to, for

            public ActionResult Create([Bind(Include="empid,lastname,firstname,title,titleofcourtesy,birthdate,hiredate,address,city,region,postalcode,country,phone,mgrid")] Employee employee)
            {
                if (ModelState.IsValid)
                {
                    db.Employees.Add(employee);
                    db.SaveChanges();
                    return RedirectToAction("Index");
                }
    
                ViewBag.mgrid = new SelectList(db.Employees, "empid", "lastname", employee.mgrid);
                return View(employee);
            }
    
            // GET: /Employee/Edit/5
            public ActionResult Edit(int? id)
            {
                if (id == null)
                {
                    return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
                }
                Employee employee = db.Employees.Find(id);
                if (employee == null)
                {
                    return HttpNotFound();
                }
                ViewBag.mgrid = new SelectList(db.Employees, "empid", "lastname", employee.mgrid);
                return View(employee);
            }
    
            // POST: /Employee/Edit/5

            [HttpPost]
            [ValidateAntiForgeryToken]
            public ActionResult Edit([Bind(Include="empid,lastname,firstname,title,titleofcourtesy,birthdate,hiredate,address,city,region,postalcode,country,phone,mgrid")] Employee employee)
            {
                if (ModelState.IsValid)
                {
                    db.Entry(employee).State = EntityState.Modified;
                    db.SaveChanges();
                    return RedirectToAction("Index");
                }
                ViewBag.mgrid = new SelectList(db.Employees, "empid", "lastname", employee.mgrid);
                return View(employee);
            }
    
            // GET: /Employee/Delete/5
            public ActionResult Delete(int? id)
            {
                if (id == null)
                {
                    return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
                }
                Employee employee = db.Employees.Find(id);
                if (employee == null)
                {
                    return HttpNotFound();
                }
                return View(employee);
            }
    
            // POST: /Employee/Delete/5
            [HttpPost, ActionName("Delete")]
            [ValidateAntiForgeryToken]
            public ActionResult DeleteConfirmed(int id)
            {
                Employee employee = db.Employees.Find(id);
                db.Employees.Remove(employee);
                db.SaveChanges();
                return RedirectToAction("Index");
            }
    
            protected override void Dispose(bool disposing)
            {
                if (disposing)
                {
                    db.Dispose();
                }
                base.Dispose(disposing);
            }
        }
    }
    
    

    It will also create a folder ‘Employee‘ in Views with a list of cshtml (Create, Delete, Details, Edit, Index)

    Build and run by pressing F5, and go to the similar link in the browser like:
    http://localhost:49481/employee

    I removed some of unwanted items in index.cshtml. My index page looked like:

    Summary

    Using Entity Framework, Visual Studio 2013 can easily generate a model from database, and scaffold a controller and generate all the views based on default templates and standard CRUD operations on EF.

    The advantage of this process is that the model, controller and view can be easily re-generated by repeating the above step 2 and 3 if the table structure in the underlying physical table is changed.

    The disadvantage is also obvious. Whatever customization made after the generation on (M. V. C) will have to be repeated after re-generation.
