備註

Modifications to this property are not persisted in the upstream column or in the virtual column. When new input columns are created from a virtual column, the length property of the new column matches this value.

The Length property is set for the following data types.

  • DT_WSTR

  • DT_BYTES

  • DT_STR

  • DT_TEXT

  • For all other data types, Length is zero.
