<Result> = HViewToFile(<View>)
<Result>: Boolean
  • True if the view was transferred into the data file,
  • False otherwise. HError returns more details about the problem.
<View>: Character string
Name of view used. If this name is not specified, HViewToFile will handle the last view used by an HFSQL function (function starting with "H").
Remarks
If an error occurs when updating the data file, HError is used to identify the records that caused the problem. Simply loop through the view again and run HError on each record in the view.
