HDeleteFile (Function) In french: HSupprimeFichier
Available only with this kind of connection
Deletes HFSQL data files (.fic, .ndx, .ftx, .sdx and .mmo files, if any) from the server.
MaConnexion is Connection
IF HDeleteFile(MaConnexion, ".\sauvegarde\fichierclient_sov.fic") = False THEN
Error(HErrorInfo())
END
Syntax
<Result> = HDeleteFile(<Connection> , <Data file path> [, <Options>])
<Result>: Boolean - True if the data file was deleted,
- False if an error occurred (the data file does not exist on the server for example). HError is used to identify the error.
<Connection>: Character string or Connection variable Connection in which the data file must be deleted. This connection corresponds to: <Data file path>: Character string Physical name and path of the data file to delete. The path is relative to the database: the name of the database must not be specified in the path. The ".fic" extension of the data file must be specified. <Options>: Optional Integer constant (or combination of constants) By default, when deleting a data file: - the files corresponding to the logs are not deleted,
- the files corresponding to the transactions are deleted.
This parameter is used to modify this behavior:
| | hDeleteLog | Deletes the Log file and all the logged operations associated with the deleted data file. | hDestroyLink | Deletes all links related to the deleted data file. | hKeepTRS | Keeps the transaction file associated with the deleted data file. |
Remarks Deleting a data file The data file can be deleted only if it is not currently used (which means if it is not used by a query, a view, another window, a thread or a component with independent HFSQL context). The data file is automatically closed in the HFSQL context that calls HDeleteFile. A WLanguage error occurs if the data file is used in a context or by an application. Names of files and directories on the LINUX server On a LINUX server, the names of data files (.fic, .ftx, .sdx, .ndx and .mmo files, if any) must be in lowercase and must not contained accented characters.
