Percentage Sampling Transformation Editor

Use the Percentage Sampling Transformation Editor dialog box to split part of an input into a sample using a specified percentage of rows. This transformation divides the input into two separate outputs.

To learn more about the percentage sampling transformation, see Percentage Sampling Transformation.

Options

  • Percentage of rows
    Specify the percentage of rows in the input to use as a sample.

    The value of this property can be specified by using a property expression.

  • Sample output name
    Provide a unique name for the output that will include the sampled rows. The name provided will be displayed within the SSIS Designer.

  • Unselected output name
    Provide a unique name for the output that will contain the rows excluded from the sampling. The name provided will be displayed within the SSIS Designer.

  • Use the following random seed
    Specify the sampling seed for the random number generator that the transformation uses to create a sample. This is only recommended for development and testing. The transformation uses the Microsoft Windows tick count if a random seed is not specified.
