属性值

true if the input columns in the IDTSInputColumnCollection90 reference upstream columns; otherwise, false.

备注

An invalid input column is a column whose LineageID property does not match the LineageID of an IDTSOutputColumn90 in the IDTSOutput90 of the upstream component.

This method checks each of the IDTSInput90 objects in the IDTSComponentMetaData90 for the existence of invalid columns. If found, the RemoveInvalidInputColumns method can be called to automatically remove the invalid columns.
