HStatNbRec (Function)

In french: HStatNbEnr

Available only with these kinds of connection

Returns the number of entries for a given key item. This number was calculated during the last statistical calculation.

Example

// Calculate statistics for the CustomerName key in the Customer table
ResStat = HStatNbRec(Customer, CustName)

Syntax

<Result> = HStatNbRec([<Table> [, <Key item>]])

<Result>: Integer

Number of entries found for the specified item.
Corresponds to the hInvalidRecNum constant if:
the statistics have never been calculated for the specified item.
the statistics are not supported by the specified type of item. HFSQL allows you to perform statistical calculations on key items only.

<Table>: Optional character string

Name of the table used. If this name is not specified, HStatNbRec will use the last table used by the last HFSQL function (function starting with "H").

<Key item>: Optional character string

Name of the key item used to calculate statistics. If this name is not specified, HStatNbRec will use the last item used by the last HFSQL management function (function starting with "H").

Remarks

The statistics can be updated by HIndex and HStatCalculate.
In the HFSQL Classic tables, the statistical calculations can only be performed on key items.
