주의

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.

DataType	Length	Scale	Precision	CodePage
DT_DECIMAL	Not enforced	Greater than or equal to 0, and less than or equal to 28.	Not enforced	Not enforced
DT_NUMERIC	Not enforced	Greater than or equal to 0, and less than or equal to 38, and less than or equal to the specified precision.	Greater than or equal to 1, and less than or equal to 38.	Not enforced
DT_BYTES	Greater than 0, and less than or equal to 8000.	Not enforced	Not enforced	Not enforced
DT_DBTIME2 DT_DBTIMESTAMP2 DT_DBTIMESTAMPOFFSET	Not enforced.	Greater than or equal to 0, and less than or equal to 7.	Not enforced.	Not enforced.
DT_STR	Greater than 0 and less than or equal to 8000.	Not enforced	Not enforced	Not 0.
DT_TEXT	Not enforced	Not enforced	Not enforced	Not 0.
DT_WSTR	Greater than 0 and less than or equal to 4000.	Not enforced	Not enforced	Not enforced.

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.
