- Functions that modify the result of HOut
- Miscellaneous
HOut (Function) In french: HEnDehors Used to find out whether the record on which you want to be positioned is located outside the data file, filter, view or query.
HReadFirst(Customer, Name) WHILE HOut() = False // Process the record HReadNext(Customer, Name) END
Syntax
<Result> = HOut([<Data file>])
<Result>: Boolean - True if attempt to position on a record located outside the data file, filter, view or query. In this case, the current record corresponds to the one before the move operation.
- False if no problem occurred: the current record belongs to the data file, filter, view or query.
<Data file>: Optional character string Name of data file, filter, view or query onto which a positioning attempt was performed. If this name is not specified, HOut will use the last data file (filter, view or query) used by the last HFSQL function (function starting with "H").
Remarks Functions that modify the result of HOut The following functions modify the value returned by HOut: Miscellaneous - HOut corresponds to the h.Out variable available in WINDEV 5.5. This variable is kept for backward compatibility.
- Once a locked record is read, the data file is not read (HErrorLock returns True and HOut returns True).
Therefore, if the read operation is performed while looping through an HFSQL data file, the iteration is interrupted.
