Title: Distinguish between the two categories of functions in SQL.
Course: Database Design and Management (Oracle) (10052) > Section: Performing Single-Row Functions

Distinction should include

- single-row functions, which return a result (e.g., character, number, date, conversion) for a selected row
- group functions (aggregate functions), which select multiple rows of data but return only one result (i.e., AVG, COUNT, MAX, MIN, STDDEV, SUM, VARIANCE).
