- HSecurity and HFlush functions
HSecurity (Function) In french: HSécurité
  Available only with these kinds of connection
Enables or disables the automatic security mechanism on one or more data files. HSecurity(False)
HSecurity(True)
Syntax
<Result> = HSecurity([<Data file>, ] <Security level>)
<Result>: Integer Former security level (before running HSecurity). <Data file>: Optional character string Name of the data file used.
If this name is not specified, HSecurity manipulates all the data files defined in the analysis.
<Security level>: Integer or boolean Requested security level:- 0 or False (default): Safety mechanism disabled. Data is written to data files at the highest speed possible.
- 1 or True: Security mechanism activated: writing speed is slower than with the HSecurity(0) option, but security is guaranteed when writing to data files.
- 2: Maximum security mechanism: Data file writing speed is slower than with the HSecurity(1) option..
Remarks HSecurity and HFlush functions HSecurity and HFlush can both be used to force a physical write operation on disk. However: - HSecurity forces the data file(s) to be written. The HFSQL engine automatically performs the write operation. The data files are not closed during this write operation. This results in slower write speeds.
- HFlush forces a write operation to the data files when it is called. The data files are closed and then re-opened during this write operation. The write operation is not slowed down.
