Objekt TKAPBtrTable

Objekt TKAPBtrTable

Tato třída slouží pro manipulaci s databázovými tabulkami ve skriptovacím programovacím jazyku. Je možné otevřít tabulku (konkrétní složka je určena automaticky na základě aktuální databáze, do které je uživatel přihlášen), procházet záznamy tabulky, filtrovat záznamy, načítat či měnit hodnoty z jednotlivých polí záznamu apod.
