I need to display a particular column in my SQL result only if it is not null. If it is null, I don’t want that column to appear at all in my result.
Is there a way to express this condition in SQL?

This wouldn’t make sense because a query may return multiple rows. One row may have a value for the column in question and the next may not have a value. Then a conditional column would create a structural inconsistency between returned rows.
