- Filtered source
- Data source: View or query
<Source>.ToFile (Function) In french: <Source>.VersFichier
  Available only with these kinds of connection
Copies a data source (file, query, view, ...) to a physical HFSQL data file with the same description. This data file is neither encrypted nor password protected. This function can be used, for example, to save a history: a query selects all records for the year 2019, the result is transferred to a data file, and a new query deletes all records for the year 2019. IF MaVue.VersFichier("C:\temp\Test.fic") = True THEN
Info("Données transférées dans un fichier de données")
END
