Hi,
das habe ich gelesen, mag es in einem Kosch Buch gewesen sein, oder im Entwickler. Auf die Schnelle habe ich folgendes gefunden:
http://community.borland.com/article...,27659,00.html
Zitat:
IBDataset - This is the main data aware control I recommend using. It has advantages of having all the Live mode
SQL statements (InsertSQL, DeleteSQL, ModifySQL and RefreshSQL) built in. It can still use an UpdateObject for more complicated update sequences. The major difference between an IBDataset and an IBQuery is the use of the native IBXSQLVAR instead of TParam. This has the advantage of being able to
handle INT64 data types under
IB 6.0, but has a disadvantage of the Params not accessible at design time. Expect future versions to be able to publish the Params property.
Zitat:
IBQuery is a read only component by default. To make the component Read Write an IBUpdateSQL object needs to be tied to the IBQuery through the UpdateObject property. One main difference between IBQuery in this configuration and IBDataset is the Edit functionality. When posting an edit IBUpdateSQL will raise an
exception if you do not modify one and only one record. IBDataset will allow you to update 0 or more records without any exceptions.
Zumindest hier steht eindeutig, dass neue Features von
IB/
FB (z.B. INT64) von TIBQuery nicht unterstützt werden.
Wenn Du mehr Quellen brauchst, musst Du mir Zeit geben.
