Columns in the PDV
- [Narrator] It's important to think about whether you need columns for processing when you are deciding how to drop or keep them. When you use a drop equal or keep equal data set option on a table in the SET statement the excluded columns are not read into the PDV so they are not available for processing. When you use a drop or keep statement or a drop equal or keep equal data set option in the data statement the columns are included in the PDV and can be used for processing. They are flagged to be dropped when an implicit or explicit output is reached.
