Parámetros

  • lLength
    The length of the column.
  • lPrecision

  • lCodePage
    The code page of the column.

Notas

The parameters of this method are properties of the IDTSOutputColumn90 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.
