Convert DB to SDF

Understanding db and sdf file formats

DB files are generic database files that can be created by various database management systems, such as SQLite, dBASE, or Microsoft Access. The structure and content of a DB file depend on the software that created it, making the format quite versatile but also ambiguous without knowing its origin.

SDF files refer to SQL Server Compact Edition Database files. These are used by Microsoft SQL Server Compact (SQL CE), a lightweight, embedded database solution for desktop and mobile applications. SDF files store relational data in a compact, single-file format.

Why convert db to sdf?

Converting a DB file to an SDF file is often necessary when migrating data from a generic or legacy database system to a modern, portable SQL Server Compact Edition environment. This enables easier integration with .NET applications and mobile solutions.

How to convert db to sdf

The conversion process depends on the original DB file's format. If your DB file is an SQLite database, you can use tools to export the data and then import it into an SDF file. If it's from another system, you may need to first export the data to a common format like CSV or SQL, then import it into SQL Server Compact.

Recommended software for db to sdf conversion

• SQL Server Compact Toolbox (for Visual Studio): This free extension allows you to import data from various sources, including SQLite and CSV, into an SDF file. Use Tools → SQL Server Compact Toolbox → Import to start the process.
• DBConvert/DBSync for SQLite and SQL Server: This commercial tool supports direct conversion from SQLite DB files to SQL Server Compact SDF files, streamlining the migration process.
• Microsoft SQL Server Management Studio (SSMS): While SSMS does not natively support SDF files, you can use it to export data from a DB file (if supported) to SQL scripts, then use SQL Server Compact Toolbox to import those scripts into an SDF file.

Step-by-step conversion example using SQL Server Compact Toolbox

1. Install SQL Server Compact Toolbox in Visual Studio.
2. Open the Toolbox and create a new SDF database via New Database.
3. Import data from your DB file (or from a CSV/SQL export) using Import options.
4. Map tables and fields as needed, then complete the import to generate your SDF file.

Tips and considerations

• Always back up your original DB file before conversion.
• Check for compatibility between data types in the source and target formats.
• If your DB file is not recognized, try exporting its data to CSV or SQL first.
