HGetCurrentPosition (Function)
In french: HPositionCourante
ODBCNot available with this kind of connection
Returns the approximate position of current record in the data file. This position is given in relation to a specific item.
Note: The position is given approximately for performance reasons. The position is calculated according to the position in the index. Note: From version 19, HFSQL is the new name of HyperFileSQL.
Example
HSeek(CUSTOMER, NAME, "Smith")
IF HFound(CUSTOMER) = True THEN
        Percentage is int = HGetCurrentPosition(CUSTOMER, NAME)/10
        Info("The first SMITH is at " + Percentage + "% of CUSTOMER on the NAME key")
END
Syntax
<Result> = HGetCurrentPosition([<File name> [, <Item name>] [, <Precision>]])
<Result>: Integer
  • Approximate current position, plotted to the [1;1000] interval.
  • -1 if an error occurs (empty data file, filter returning no result, etc.). HErrorInfo returns more details about the problem.
<File name>: Optional character string (with or without quotes)
Name of data file used. If this name is not specified, HGetCurrentPosition uses the last data file used by the last HFSQL management function (starting with "H").
<Item name>: Optional character string (with or without quotes)
Name of item used. If this name is not specified, HGetCurrentPosition uses the last item used by the last HFSQL management function (starting with "H").
<Precision>: Optional integer
Defines the precision with which the position is evaluated. Caution: The higher the precision, the longer it takes to evaluate the position in the file.
hPrecisionLowLow precision.
hPrecisionMedium
(default value)
Medium precision.
hPrecisionHighHigh precision.

Position in relation to a key item or to a non-key item

For a key item, the position returned is relative to the position of the record in the index of this item.
For a non-key item, the position returned is relative to the record number in the data file (see HRecNum).

Position in a filtered browse

If a filter with bounds is defined (HFilter without condition string but with lower and upper bounds), the returned position is relative to the records selected by the filter.
If a condition string is given to HFilter, the returned position ignores the filter.
