Example

See additional examples

IF HState(CUSTOMER) = hStateActive THEN
// Processes
END

Syntax

<Result> = HState([<File Name> [, <Record Number>]])

<Result>: Integer constant

Status of record:
hStateActive The record is active.
hStateInvalid Record status not found (error).
hStateCrossed The record is crossed.
hStateDel The record is deleted.

<File Name>: Optional character string (with or without quotes)

Name of data file used. If this name is not specified, HState handles the last data file used by the last function for HFSQL management (starting with the letter H).

<Record Number>: Optional integer

Number of the sought record. If this number is not specified (or if it is equal to 0), HState handles the current record. The current record is not read again.

Remarks

Record number not specified

HState reads no record if <Record Number> is not specified.

In a network application, we advise you to read the record again before the call to HState to make sure that the record was not deleted. With HRead for example:

HRead(FileName, hCurrentRecNum)

Data files in Hyper File 5.5 format

With the Hyper File 5 engine, the record must be read again in order for its status to be refreshed. Indeed, if the record is not read again after HDelete or HCross, HState always returns hStateActive.

This operating mode is no longer available in the HFSQL Classic engine. Once HDelete or HCross was used on the current record, HState returns the current record status.

xBase files

HDelete and HCross have the same effect: the record is crossed but it is not deleted. Therefore, the record can be re-enabled by HModify.

In this case, HState returns the hStateCrossed constant for a deleted record (instead of hStateDel).
