Notes

The parameters of this method are individual read-only properties of the IDTSOutputColumn100 object whose values are set by using this method. The method is required because the values of these properties are dependent on each other. This method provides a mechanism for updating these properties atomically, allowing the data flow to enforce the dependencies. The eDataType parameter is used to determine the other checks to perform on the parameter values.

The following table shows the dependencies that are enforced when setting the data type properties of an output column.

For a brief overview of the codepages supported by the Moteur de base de données SQL Server, and a partial list of codepage values, see Architecture des pages de codes.

The use of the SetDataTypeProperties method is discussed or demonstrated briefly in Developing a Custom Source Component, Developing a Custom Transformation Component with Synchronous Outputs, and Developing a Custom Transformation Component with Asynchronous Outputs.
