I am using SSIS for ETL.
As part of transformation I dont want to process the records row by row. I want to apply the transformation to the complete column .
1) Using derived column for transformation process the records row by row and it affects performance. Am I right?
2) Can I use script component to avoid row by row processing. Even in script component I see the description as ''This method is called once for every row that passes through the component from Input0."
So what is the best way to perform transformation.
