<Source>.ErrorModification (Function)
In french: <Source>.ErreurModification
ODBCNot 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).
Remark: From version 19, HFSQL is the new name of HyperFileSQL.
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
