ResStat = Customer.StatNbRec(CustName)

Syntax

<Result> = <Source>.StatNbRec([<Key item>])

<Result>: Integer

Number of entries found for the specified item.

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.

<Source>: Type corresponding to the specified source

Name of data file used.

<Key item>: Optional character string (with or without quotes)

Name of key item used to perform the statistical calculation. If this name is not specified, <Source>.StatNbRec will use the last item used by the last HFSQL management function (function starting with "H").

Remarks

The statistics can be updated by <Source>.Index and <Source>.StatCalculate.
In the HFSQL Classic data files, the statistical calculations can only be performed on key items.
