What are summary column and placeholder column in reports?
Answer / Swadesh Deepak
"Summary column" in Oracle Reports is a special type of column used to display calculations such as totals, subtotals, minimum, maximum, average, and count. On the other hand, "placeholder columns" are columns that do not have a specific data source or SQL query associated with them and are used primarily for layout purposes, like setting up group boundaries or creating blank spaces.n
