備註
An IDTSVirtualInputColumn100 column represents the IDTSOutputColumn100 of an upstream component in the data flow layout. Its properties are the same as those in the output column. Modifications to virtual column properties are not persisted in the virtual column, or in the output column of the upstream component. The upstream component might or might not be directly upstream from the component with the virtual input column.
