How Do I Find My SQL Server Connection String and Database Location?

Finding Your SQL Server Connection String and Database Path

Developing database-driven applications requires knowing your connection string and database location. This guide explains how to find this information for SQL Server databases created with SQL Server Management Studio (SSMS).

Locating the Connection String

1. Open Visual Studio and navigate to View > Server Explorer.
2. Establish a connection to the server hosting your database.
3. Select the connected server and press F4 or Alt Enter to open the Properties window.
4. The connection string is displayed under the "Connection String" property.

Advanced Connection Options

The "Advanced..." button within the Server Explorer's connection dialog allows customization of advanced settings like Multiple Active Result Sets (MARS), connection resiliency, timeout values, and connection pooling.

Database File Location

Databases created through SSMS reside on a specific server instance. Application deployment necessitates:

1. Backing up the database.
2. Restoring the backup on the target SQL Server instance.

Alternative Deployment Strategies

• SQL Server Express (localDB in SQL Server 2012 and later): Create a data file using SQL Server Express. This approach allows deployment of the database file alongside your application.
• ASP.NET App_Data Folder: Storing your SQL Server database within the App_Data folder is suitable for use with SQL Server Express. The database file will be located within this folder.
