Convertir FDB en SDF

Comprendre les formats de fichiers fdb et sdf

FDB files are database files used by Firebird, an open-source relational database management system. These files store structured data, tables, and relationships in a format optimized for Firebird's engine.

SDF files are SQL Server Compact Edition Database files, used by Microsoft SQL Server Compact (SQL CE). SDF files are lightweight, single-file databases suitable for mobile and desktop applications.

Why convert fdb to sdf?

Converting an FDB file to an SDF file is often necessary when migrating data from a Firebird-based application to one that uses SQL Server Compact, or for compatibility with Microsoft development tools.

How to convert fdb to sdf

There is no direct one-step converter for FDB to SDF due to differences in database engines. The process typically involves exporting data from Firebird and importing it into SQL Server Compact. Here’s a step-by-step approach:

1. Export data from Firebird (FDB):
   • Use Firebird’s isql tool or a GUI like FlameRobin to export tables to CSV or SQL scripts.
   • Example with isql: isql -u SYSDBA -p masterkey -d database.fdb -o output.sql
2. Create a new SDF database:
   • Use SQL Server Compact Toolbox (a Visual Studio extension) or SQL Server Management Studio (SSMS) with SQL CE support.
   • In Toolbox: New Database → SQL Server Compact 4.0 (*.sdf)
3. Import data into SDF:
   • Use the Toolbox’s Script → Execute SQL to run the exported SQL, or use the Import Data wizard for CSV files.
   • Map data types and adjust SQL syntax as needed for SQL CE compatibility.

Logiciel recommandé pour la conversion

• Firebird’s FlameRobin (pour l’export Firebird) : Outil d’administration de base de données Firebird libre et multiplateforme.
• SQL Server Compact Toolbox : Extension Visual Studio pour gérer les fichiers SDF, importer des données, et exécuter des scripts.
• DBConvert : Outil commercial supportant la conversion de Firebird vers SQL Server, pouvant être adapté pour SQL CE.

Résumé

Bien qu’il n’existe pas de convertisseur direct de FDB à SDF, le processus consiste à exporter les données de Firebird et à les importer dans SQL Server Compact en utilisant des outils comme Firebird’s FlameRobin et SQL Server Compact Toolbox. Il est nécessaire de faire un mapping précis des types de données et de la syntaxe SQL pour réussir la migration.
