Characteristics of a row

  • Each row element is changed into the type of the associated column.
  • If one of the elements corresponds to an empty string ("") or to 0 (depending on the column type), its value will be overwritten.
    For example:
    TABLE_TableClient.Modifie("Dubois" + TAB + "Pierre" + TAB + "" + ...
    TAB + "21/06/72")
  • If an element corresponds to the calculation result, the numeric expression must be enclosed in brackets.
    For example:
    TABLE_TableCalcul.Modifie((53+29) + TAB + (83-21))
  • To modify the value of an element in a row, use the following syntax:
    NomTable.NomColonne[IndiceLigne] = NouvelleValeur
