Stored procedures
Returns the approximate position of current record in the data file. This position is given in relation to a specific item.
Remark: The position is given approximately for performance reasons. The position is calculated according to the position in the index.
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([<Data file> [, <Item>] [, <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.
<Data file>: Optional character string
Name of the data file used. If this name is not specified, HGetCurrentPosition will use the last data file used by the last HFSQL function (function starting with "H").
<Item>: Optional character string
Name of the item used. If this name is not specified, HGetCurrentPosition will use the last item used by the last HFSQL management function (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.
hPrecisionHighHigh precision.
hPrecisionLowLow precision.
hPrecisionMedium
(default value)		Medium precision.

PHP This parameter is ignored.
Java This parameter is ignored. The calculation is always performed with a high 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 iteration

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.
