備註
The parameters of this method are properties of the IDTSOutputColumn100 object that are individually read-only, and must be set by using this method. This method is required because the values of these properties depend on each other. It provides a mechanism for updating these properties at the same time and enables the component and the data flow task to enforce the dependencies. The eDataType parameter dictates the requirements of the other parameter values.
The following table lists the rules that must be adhered to when setting the data type properties of an output column.
