The fpdbfexport module is part of fpDBExport in the FreePascal FCL database modules.
This export module provides export to DBF formats (e.g. DBase IV format). The format is still fairly popular because it is simple, and - opposed to e.g. CSV - is clear about what data type is enclosed in its fields. Many spreadsheet and database programs can import DBF files.
In Lazarus, the DBF export component is located on the Data Export tab.
Limitations and known bugs
In FPC before 2.6.4/Lazarus before 1.2.2, exporting to e.g. dbase IV format - that has a 10 character field length limit - of fields with longer field names will throw an error unless you populate the export fieldname mapping yourself.
See the examples in your FPC source directory $(fpcdir)\source\packages\fcl-db\tests (see Databases#Running_FPC_database_tests), specifically testdbexport.pas.
The various export formats are run in
The procedure TTestDBExport.GenericExportTest shows how you can export to only supported field types (handy if you do not know in advance what field types are used in a dataset).
Another useful example is the the dbftool example included in FPC 2.6.4+:
- creating DBF files
- using DBF files
- exporting data (to DBF and other formats) using db export
