- Deleting a data file
- Names of files and directories on the LINUX server
In french: HSupprimeFichier
Available only with this kind of connection
Deletes the HFSQL data files (.fic, .ndx, .ftx and .mmo files if they exist) from the server.
MyConnection is Connection
// Deletes data files from the server
<Result> = HDeleteFile(<Connection> , <Data file path> [, <Options>])
- 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.|
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 name of data files (.fic, .ftx, .ndx and .mmo files if they exist) must be written in lowercase and they must not contain any accented characters.
