Microsoft SQL Server Express LocalDB is a feature of SQL Server Express targeted to developers. It is available on SQL Server Express with Advanced Services.

LocalDB installation copies a minimal set of files necessary to start the SQL Server Database Engine. Once LocalDB is installed, you can initiate a connection using a special connection string. When connecting, the necessary SQL Server infrastructure is automatically created and started, enabling the application to use the database without complex configuration tasks. Developer Tools can provide developers with a SQL Server Database Engine that lets them write and test Transact-SQL code without having to manage a full server instance of SQL Server.

Try it out!

• To download and install SQL Server Express LocalDB, go to SQL Server downloads. LocalDB is a feature you select during installation, and is available when you download the media. If you download the media, either choose Express Advanced or the LocalDB package. In the Visual Studio Installer, you can install SQL Server Express LocalDB as part of the .NET desktop development workload or as an individual component.

Tip

You can also install LocalDB as part of Visual Studio. During Visual Studio installation, select the .NET desktop development workload, which includes SQL Server Express LocalDB.

• Have an Azure account? Get started and spin up a virtual machine with SQL Server 2016 (13.x) already installed.

Install LocalDB

Install LocalDB through the installation wizard or by using the SqlLocalDB.msi program. LocalDB is an option when installing SQL Server 2016 Express.

Select LocalDB on the Feature Selection/Shared Features page during installation. There can be only one installation of the LocalDB binary files for each major SQL Server Database Engine version. Multiple Database Engine processes can be started and will all use the same binaries. An instance of the SQL Server Database Engine started as the LocalDB has the same limitations as SQL Server Express.

An instance of SQL Server Express LocalDB is managed by using the SqlLocalDB.exe utility. SQL Server Express LocalDB should be used in place of the SQL Server Express user instance feature, which was deprecated.

Description

The LocalDB setup program uses the SqlLocalDB.msi program to install the necessary files on the computer. Once installed, LocalDB is an instance of SQL Server Express that can create and open SQL Server databases. The system database files for the database are stored in the local AppData path, which is normally hidden. For example, C:Users<user>AppDataLocalMicrosoftMicrosoft SQL Server Local DBInstancesLocalDBApp1. User database files are stored where the user designates, typically somewhere in the C:Users<user>Documents folder.

For more information about including LocalDB in an application, see Visual Studio Local Data Overview, Create a database and add tables in Visual Studio.

For more information about the LocalDB API, see SQL Server Express LocalDB Reference.

The SqlLocalDb utility can create new instances of LocalDB, start and stop an instance of LocalDB, and includes options to help you manage LocalDB.For more information about the SqlLocalDb utility, see SqlLocalDB Utility.

The instance collation for LocalDB is set to SQL_Latin1_General_CP1_CI_AS and cannot be changed. Database-level, column-level, and expression-level collations are supported normally. Contained databases follow the metadata and tempdb collations rules defined by Contained Database Collations.

Restrictions

• LocalDB cannot be a merge replication subscriber.

• LocalDB does not support FILESTREAM.

• LocalDB only allows local queues for Service Broker.

• An instance of LocalDB owned by the built-in accounts such as NT AUTHORITYSYSTEM can have manageability issues due to windows file system redirection. Instead use a normal windows account as the owner.

Automatic and named instances

LocalDB supports two kinds of instances: Automatic instances and named instances.

• Automatic instances of LocalDB are public. They are created and managed automatically for the user and can be used by any application. One automatic instance of LocalDB exists for every version of LocalDB installed on the user's computer. Automatic instances of LocalDB provide seamless instance management. There is no need to create the instance; it just works. This feature allows for easy application installation and migration to a different computer. If the target machine has the specified version of LocalDB installed, the automatic instance of LocalDB for that version is available on the target machine as well. Automatic instances of LocalDB have a special pattern for the instance name that belongs to a reserved namespace. Automatic instances prevents name conflicts with named instances of LocalDB. The name for the automatic instance is MSSQLLocalDB.

• Named instances of LocalDB are private. They are owned by a single application that is responsible for creating and managing the instance. Named instances provide isolation from other instances and can improve performance by reducing resource contention with other database users. Named instances must be created explicitly by the user through the LocalDB management API or implicitly via the app.config file for a managed application (although managed application may also use the API, if desired). Each named instance of LocalDB has an associated LocalDB version that points to the respective set of LocalDB binaries. The instance name of a LocalDB is sysname data type and can have up to 128 characters. (This differs from regular named instances of SQL Server, which limits names to regular NetBIOS names of 16 ASCII chars.) The name of an instance of LocalDB can contain any Unicode characters that are legal within a filename.A named instance that uses an automatic instance name becomes an automatic instance.

Different users of a computer can have instances with the same name. Each instance is a different processes running as a different user.

Shared instances of LocalDB

To support scenarios where multiple users of the computer need to connect to a single instance of LocalDB, LocalDB supports instance sharing. An instance owner can choose to allow the other users on the computer to connect the instance. Both automatic and named instances of LocalDB can be shared. To share an instance of LocalDB, a user selects a shared name (alias) for it. Because the shared name is visible to all users of the computer, this shared name must be unique on the computer. The shared name for an instance of LocalDB has the same format as the named instance of LocalDB.

Only an administrator on the computer can create a shared instance of LocalDB. A shared instance of LocalDB can be unshared by an administrator or by the owner of the shared instance of LocalDB. To share and unshared an instance of LocalDB, use the LocalDBShareInstance and LocalDBUnShareInstance methods of the LocalDB API, or the share and unshared options of the SqlLocalDb utility.

Start LocalDB and connect to LocalDB

Connect to the automatic instance

The easiest way to use LocalDB is to connect to the automatic instance owned by the current user by using the connection string Server=(localdb)MSSQLLocalDB;Integrated Security=true. To connect to a specific database by using the file name, connect using a connection string similar to Server=(LocalDB)MSSQLLocalDB; Integrated Security=true ;AttachDbFileName=D:DataMyDB1.mdf.

Note

The first time a user on a computer tries to connect to LocalDB, the automatic instance must be both created and started. The extra time for the instance to be created can cause the connection attempt to fail with a timeout message. When this happens, wait a few seconds to let the creation process complete, and then connect again.

Create and connect to a named instance

In addition to the automatic instance, LocalDB also supports named instances. Use the SqlLocalDB.exe program to create, start, and stop a named instance of LocalDB. For more information about SqlLocalDB.exe, see SqlLocalDB Utility.

The last line above, returns information similar to the following.

Microsoft Sql Server Express 2012 64 Bit

Note

If your application uses a version of .NET before 4.0.2 you must connect directly to the named pipe of the LocalDB. The Instance pipe name value is the named pipe that the instance of LocalDB is listening on. The portion of the Instance pipe name after LOCALDB# will change each time the instance of LocalDB is started. To connect to the instance of LocalDB by using SQL Server Management Studio, type the instance pipe name in the Server name box of the Connect to Database Engine dialog box. From your custom program you can establish connection to the instance of LocalDB using a connection string similar to SqlConnection conn = new SqlConnection(@'Server=np:.pipeLOCALDB#F365A78Etsqlquery');

Connect to a shared instance of LocalDB

To connect to a shared instance of LocalDB add . (backslash + dot + backslash) to the connection string to reference the namespace reserved for shared instances. For example, to connect to a shared instance of LocalDB named AppData use a connection string such as (localdb).AppData as part of the connection string. A user connecting to a shared instance of LocalDB that they do not own must have a Windows Authentication or SQL Server Authentication login.

Troubleshooting

For information about troubleshooting LocalDB, see Troubleshooting SQL Server 2012 Express LocalDB.

Permissions

An instance of SQL Server 2016 ExpressLocalDB is an instance created by a user for their use. Any user on the computer can create a database using an instance of LocalDB, store files under their user profile, and run the process under their credentials. By default, access to the instance of LocalDB is limited to its owner. The data contained in the LocalDB is protected by file system access to the database files. If user database files are stored in a shared location, the database can be opened by anyone with file system access to that location by using an instance of LocalDB that they own. If the database files are in a protected location, such as the users data folder, only that user, and any administrators with access to that folder, can open the database. The LocalDB files can only be opened by one instance of LocalDB at a time.

Note

LocalDB always runs under the users security context; that is, LocalDB never runs with credentials from the local Administrator's group. This means that all database files used by a LocalDB instance must be accessible using the owning user's Windows account, without considering membership in the local Administrators group.

Microsoft Sql Server Express 2012 Sp2

Microsoft SQL Server Express is a version of Microsoft's SQL Serverrelational database management system that is free to download, distribute and use. It comprises a database specifically targeted for embedded and smaller-scale applications. The product traces its roots to the Microsoft Database Engine (MSDE) product, which was shipped with SQL Server 2000. The 'Express' branding has been used since the release of SQL Server 2005.

Capabilities[edit]

SQL Server Express provides many of the features of the paid, full versions of Microsoft SQL Server database management system.^[3] However it has technical restrictions that make it unsuitable for some large-scale deployments. Differences in the Express product include:

• Maximum database size of 10 GB per database in SQL Server 2016, SQL Server 2014, SQL Server 2012, and 2008 R2 Express^[4] (4 GB for SQL Server 2008 Express and earlier; compared to 2 GB in the former MSDE). The limit applies per database (log files excluded); but in some scenarios users can access more data through the use of multiple interconnected databases.
• No SQL Server Agent service^[5][6]
• Artificial hardware usage limits:
  • Single physical CPU, but multiple cores allowable^[7]
  • 1 GB of RAM (runs on a system with higher RAM amount, but uses only at most 1 GB per instance of SQL Server Database Engine. 'Recommended: Express Editions: 1 GB All other editions: At least 4 GB and should be increased as database size increases to ensure optimal performance.'^[8]).^[9] Express with Advanced Services has a limit of 4 GB per instance of Reporting Services (not available on other Express variants). Analysis Services is not available for any Express variant.

Unlike the predecessor product, MSDE, the Express product does not include a concurrent workload-governor to 'limit performance if the database engine receives more work than is typical of a small number of users.'^[10]

SQL Server Express includes several GUI tools for database management. These include:

• SQL Server Management Studio - since 2012 SP1;^[11] before that, only a stripped-down version called SQL Server Management Studio Express is provided
• SQL Server Configuration Manager
• SQL Server Surface Area Configuration tool
• SQL Server Business Intelligence Development Studio

The predecessor product MSDE generally lacked basic GUI management tools,^[12]

Features available in SQL Server 'Standard' and better editions but absent from SQL Server Express include:

Variants[edit]

Microsoft makes SQL Server Express available as:

• An integrated edition with management tools
• Core database-engine only
• A SQL Server Express with Advanced Services edition (first introduced relatively late in Q2 2006 compared to the original release) with a reduced-functionality version of SQL Server Reporting Services and with full-text search capabilities

In the Free 2005 Express version, for example, a standard approach to installation options was provided, as follows.Generally, the SQL 2005 Express installers are packaged with the following consistent naming convention:

SQLEXPR.EXE

Has installers for BOTH 32-bit and 64-bit processors, but is a basic install

SQLEXPR32.EXE

Has ONLY the installer for 32-bit processors (still the basic install)

SQLEXPRWT.EXE

Has installers for BOTH 32-bit and 64-bit processors and SQL Server Management Studio Express (SSMSE) (2008 R2)

SQLEXPR_ADV.EXE

Has the basics and SQL Server Management Studio Express (SSMSE) + Reporting and Full Text Queries

SQLEXPR_TOOLKIT.EXE

Has the basics and SSMSE and Business Intelligence Development Studio (BIDS)

These optional variants have gone through several service packs (SP), and each SP installer can be used without using the older ones first:

• Originals of the above files all carry the version number 9.0.1399.6
• Service Pack 2 (SP2) versions all carry the version number 9.0.3042
• Service Pack 3 (SP3) versions all carry the version number 9.00.4035
• Service Pack 4 (SP4) versions all carry the version number 9.00.5000

Version history[edit]

• Does not include Windows Server 2016 'Essentials' Edition
