Status Property (ADO Field)
Indicates the status of a Field object.
Return Value
Returns a FieldStatusEnum value. The default value is adFieldOK.
Remarks
Record Field Status
Changes to the value of a Field object in the Fields collection of a Record object are cached until the object's Update method is called. At that point, if the change to the Field's value caused an error, OLE DB raises the error DB_E_ERRORSOCCURRED (2147749409). The Status property of any of the Field objects in the Fields collection that caused the error will contain a value from the FieldStatusEnum describing the cause of the problem.
To enhance performance, additions and deletions to the Fields collections of the Record object are cached until the Update method is called, and then the changes are made in a batch optimistic update. If the Update method is not called, the server is not updated. If any updates fail then an OLE DB provider error (DB_E_ERRORSOCCURRED) is returned and the Status property indicates the combined values of the operation and error status code. For example, adFieldPendingInsert OR adFieldPermissionDenied. The Status property for each Field can be used to determine why the Field was not added, modified, or deleted.
Many types of problems encountered when adding, modifying, or deleting a Field are reported through the Status property. For example, if the user deletes a Field, it is marked for deletion from the Fields collection. If the subsequent Update returns an error because the user tried to delete a Field for which they do not have permission, the Field will have a Status of adFieldPermissionDenied OR adFieldPendingDelete. Calling the CancelUpdate method restores original values and sets the Status to adFieldOK.
Similarly, the Update method may return an error because a new Field was added and given an inappropriate value. In that case the new Field will be in the Fields collection and have a status of adFieldPendingInsert and perhaps adFieldCantCreate (depending upon your provider). You can supply an appropriate value for the new Field and call Update again.
Recordset Field Status
Changes to the value of a Field object in the Fields collection of either a Recordset are cached until the object's Update method is called. At that point, if the change to the Field's value caused an error, OLE DB raises the error DB_E_ERRORSOCCURRED (2147749409). The Status property of any of the Field objects in the Fields collection that caused the error will contain a value from the FieldStatusEnum describing the cause of the problem.
