HCopyFile (Function)
Disponible solo con este tipo de conexión
Performs an copy of a data file HFSQL (.fic, .ndx, .ftx, .sdx and .mmo files if available): - from the HFSQL server to the server (to perform a backup for example).
- from the HFSQL server to the client (to perform a local backup for example).
- from the client to the HFSQL server (to update the data files for example).
- from an HFSQL server to another HFSQL server.
Novedad versión 2024HFSQL ClusterFrom version 2024 Update 1, it is possible to use the HCopyFile function with an HFSQL cluster. In particular, it is possible to make an copy of a data file: - from the HFSQL server to a node in the HFSQL cluster.
- from a local directory to an HFSQL cluster.
HCopyFile(MaConnexion, ".\sauvegarde\fichierclient_sov.fic", MaConnexion, ".\fichierclient.fic")
HCopyFile("", "C:\Données\Client.fic", MaConnexion, "client.fic")
HCopyFile(MaConnexion, "client.fic", "", "C:\Données\Client.fic")
HCopyFile("CNX", "client.fic", "CNX2", "rep\client.fic", hNoIndex, JAUGE_MaJauge)
sMonRepertoireDestination is string = CompleteDir(fExeDir()) + "RepertoireTest\"
IF NOT fDirectoryExist(sMonRepertoireDestination) THEN fMakeDir(sMonRepertoireDestination)
HCopyFile("", sMonRepertoireDestination + "CLIENT.FIC", "", ...
CompleteDir(fExeDir()) + "CLIENT.FIC", hCopyIndex)
Sintaxis
<Result> = HCopyFile(<Destination connection> , <Destination data file> , <Source connection> , <Source data file> [, <Copy mode> [, <Progress Bar control> [, <Password>]]])
<Result>: Boolean - True if the data file was copied,
- False if an error occurs. HError is used to identify the error.
<Destination connection>: Character string or Connection variable Connection to which the data file must be copied. This connection corresponds to:If this parameter corresponds to an empty string, the destination will be the local computer. <Destination data file>: Character string Name and path of destination data file. The path and this data file are automatically created if they do not exist on the server. If the destination data file is found on the server, the path is relative to the database. Caution: the extension of the '.fic' file must be specified. <Source connection>: Character string or Connection variable Connection from which the data file must be copied. This connection corresponds to: <Source data file>: Character string Name and path of the source data file (to copy). If the source data file is found on the server, the path is relative to the database. Caution: - the extension of the '.fic' file must be specified.
- the '.mmo' file, if any, will be automatically copied.
<Copy mode>: Optional Integer constant Copy mode used:
| | hCopyIfNotFound | Copies the data file only if it does not exist at the specified location on the destination computer. | hCopyIndex | The of the data file index(es) are copied (NDX file, SDX file and FTX file if available). | hCreateIndex | of the data file index(es) are not copied (NDX file, SDX file and FTX file if they exist). They are automatically re-created on the destination via a reindex operation. If the data file is password-protected, the <Password> parameter must be specified. | hNoIndex | The of the data file index(es) are not copied (NDX file, SDX file and FTX file if they exist). |
<Progress Bar control>: Optional control name Name of Progress Bar control found in the window, used to show the progress of copy. <Password>: Optional character string File password (if it exists). This password is required if the hCreateIndex constant is used. Observaciones Operating mode of HCopyFile - The copied data file is unlocked, as well as the records found in the data file.
- The index is not copied if it does not exist or if it is corrupted.
- The password is not required to copy the data file. However, the copied data file remains password-protected.
- It is not possible to copy data files to a source server of a SPARE replication server.
- Data file in transaction: before copying the data file, we advise you to:
Use conditions - You can also copy a data file from the client computer to the same client computer. In this case, this function is equivalent to fCopyFile.
- This function is used to copy files to an HFSQL server (in Client/Server mode). This function cannot be used with an external server (Oracle or other).
- To copy an HFSQL data file from a local computer to the server, all the users must have freed such file beforehand. No connection to the data file must be in progress, or the copy will fail. To prevent any new connection to the data file, you can:
- Case of replicated data files (replication between servers):
For a replicated data file, HCopyFile must not be used to copy a data file to the server: the copy is not possible. However, a data file can be copied from the server to the client computer. Novedad versión 2024Case of an HFSQL cluster- If the data files to be copied use enhanced security, it is necessary to specify the of the data file password via the parameter . This password is required to synchronize data files on the various nodes..
- To use the HCopyFile function with an HFSQL cluster, it is necessary that both the HFSQL cluster and the client application use at least version 2024 Update 1.
Names of data files and directories on the server - The names of data files (.fic, .ndx, .ftx, .sdx and .mmo files if they exist) on the server must not include accents.
- On a LINUX server, the name of the data files must be written in lowercase characters.
