I'm not sure I agree that's unexpressive. When you consider the relational model, it's not clear to me what "deleting
thevalue of a column" means. It could be:
1. Removing the current value, which begs the question of "replacing it with what?"
2. Dropping the column, for which we already have ALTER TABLE ... DROP COLUMN.
Can you give a bit more detail about what the state of the table is when you have "deleted the value of a column
directly"?
