<Source>.ErrorModification (Function)

In french: <Source>.ErreurModification

Not available with this kind of connection

If a modification conflict occurs, returns the value of a record item. This value is returned as a character string (empty string for binary memos).

Remark: this function must only be used during a custom management of modification conflicts (in a procedure or window called by the HFSQL engine to process the modification conflict for example).

Example

LOOP
// Extracts the nth item from the list of items in conflict
AnItem = ItemList.ExtractString(i, CR)
// Exit if no other item
IF AnItem = EOT THEN BREAK // Exit if no other item in conflict

// Displays the value of the item for the source record
Trace(FileName.ErrorModification(AnItem, hRecRead))
// Displays the value of the item for the file record
Trace(FileName.ErrorModification(AnItem, hRecFile))
// Displays the value of the item for the user record
Trace(FileName.ErrorModification(AnItem, hRecUser))
END

Syntax

<Result> = <Source>.ErrorModification(<Item> [, <Item index>] , <Record to read>)

<Result>: Character string

Content of the requested item,
Empty string ("") if no error occurred.

<Source>: Type corresponding to the specified source

Name of data file used.

<Item>: Character string

Name of item used.

<Item index>: Optional integer

Subscript of the item for array items only. This parameter is not required for the other types of items.

<Record to read>: Integer constant

Used to specify the record for which the information must be read:
hRecFile Value of the item currently saved in the data file.
hRecRead Value of the item for the source record (read before the modification performed by <Source>.Modify).
hRecUser Value of the item for the current record when the modification is performed (<Source>.Modify).
