J# 支持显式接口实现的使用，但不支持新接口实现的声明。

参数

  • bMatch
    Specifies whether the IDTSOutputColumn90 column should be set to match the IDTSExternalMetadataColumn90 column.

返回值

The IDTSExternalMetadataColumn90 that is mapped to the output column.

备注

Call this method to map an IDTSOutputColumn90 column to a column in the ExternalMetadataColumnCollection of the output. If the bMatch parameter is true, and the data type properties of the two columns differ, the component will modify the data type properties of the output column to match the properties of the external metadata columns.
