Paramètres

• eDataType
  The DataType of the column.

• lLength
  The length of the column.

• lPrecision
  The total number of digits of the output column.

• lScale
  The number of decimal places of the output column.

• lCodePage
  The character set of the output column.

Notes

Exemple de code mis à jour :17 juillet 2006

The parameters of this method are individual read-only properties of the IDTSOutputColumn90 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.

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.
