Convert FDB to SDF

Understanding fdb and sdf file formats

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.

Recommended software for conversion

• FlameRobin (for Firebird export): Free, cross-platform Firebird database administration tool.
• SQL Server Compact Toolbox: Visual Studio extension for managing SDF files, importing data, and running scripts.
• DBConvert: Commercial tool supporting Firebird to SQL Server conversions, which can be adapted for SQL CE.

Summary

While there is no direct FDB to SDF converter, the process involves exporting data from Firebird and importing it into SQL Server Compact using tools like FlameRobin and SQL Server Compact Toolbox. Careful mapping of data types and SQL syntax is required for a successful migration.
