true if the input columns in the IDTSInputColumnCollection100 reference upstream columns; otherwise, false.
Osservazioni
An invalid input column is a column whose LineageID property does not match the LineageID of an IDTSOutputColumn100 in the IDTSOutput100 of the upstream component.
This method checks each of the IDTSInput100 objects in the IDTSComponentMetaData100 for the existence of invalid columns. If found, the RemoveInvalidInputColumns method can be called to automatically remove the invalid columns.
