Log File


Log File -> Function result

Parameter	Type	Description
Function result	String	Long name of the database log file

Description

The Log File command returns the long name (i.e. the complete pathname of the file, including its name) of the current log file of the open database.

If the database is operating without a log file, the command returns an empty string and the system variable OK is set to 0.

If the database operates with a log file, the system variable OK is set to 1. The pathname returned by the command is expressed with the syntax of the current platform.

WARNING: If you execute this command from a 4D Client machine, only the log file name is returned, not the long name

System variables and sets

If the database is operating without a log file, the system variable OK is set to 0; otherwise, it is set to 1.
If for some reason the log file becomes unavailable during a working session, error 1274 is generated and 4D Server does not allow users to write data anymore. When the log file is available again, it is necessary to do a backup.
