Qu'est-ce qu'un fichier SDF ?

An SDF file contains a compact relational database saved in the SQL Server Compact (SQL CE) format, which is developed by Microsoft. It is designed for applications that run on mobile devices and desktops and contains the complete database contents, which may be up to 4GB in size.

To open an SDF file with Visual Studio, select View → Server Explorer → Data Connections → Add Connection..., change the data source to "Microsoft SQL Server Compact," click Browse..., and select the SDF file.

To open an SDF file with LINQPad, follow these steps:

  1. Click "Add connection" in the top-left pane
  2. Select "Build data context automatically," choose "LINQ to SQL," and click Next >.
  3. Select "SQL CE 4.0 (auto-install)" in the Provider section.
  4. Click "Attach database file" in the Database section, click "Browse," and choose the SDF file.

REMARQUE: Previous versions of SQL Server Compact were distributed as SQL Server for Windows CE and SQL Server Mobile Edition.

An SDF file is a data file saved in the Standard Database Format (SDF), which stores data in a structured format that consists of values organized into fields of fixed lengths. Various database and data analysis programs can import and export SDF files, making SDF a common format for transferring data between different programs.

Plus d'informations

The Standard Database Format is one of several data formats that use the .sdf file extension. Other formats include the Spatial Data Format, SQL Server Compact Database Format, and the Structure Data Format.

While an application can open an SDF file saved in one format, it likely does not support SDF files saved in other formats. For example, the Avogadro molecule editor and visualizer can open SDF files in the Structure Data Format but cannot open SDF files in the Standard Database Format.

Comment ouvrir un fichier SDF

You can open SDF files with various programs, including dBase, a database management system that supports many modern database engines.
