The Copy Column transformation creates new columns by copying input columns and adding the new columns to the transformation output. Later in the data flow, different transformations can be applied to the column copies. For example, you can use the Copy Column transformation to create a copy of a column and then convert the copied data to uppercase characters by using the Character Map transformation, or apply aggregations to the new column by using the Aggregate transformation.
Configuration of the Copy Column Transformation
You configure the Copy Column transformation by specifying the input columns to copy. You can create multiple copies of a column, or create copies of multiple columns in one operation.
This transformation has one input and one output. It does not support an error output.
You can set properties through the SSIS Designer or programmatically.
