備註
The columns in an IDTSBuffer100 contain metadata about the column data. This information is represented by the DTP_BUFFCOL structure. This structure is retrieved for an individual column by calling the GetColumnInfo method.
The values contained in the fields in the structure reflect the values contained in the IDTSOutputColumn100 that originally inserted the column into the data flow.
