Vertica analytics are SQL functions based on the ANSI 99 standard. These functions handle complex analysis and reporting tasks—for example:
- Rank the longest-standing customers in a particular state.
- Calculate the moving average of retail volume over a specified time.
- Find the highest score among all students in the same grade.
- Compare the current sales bonus that salespersons received against their previous bonus.
Analytic functions return aggregate results but they do not group the result set. They return the group value multiple times, once per record. You can sort group values, or partitions, using a window
ORDER BY clause, but the order affects only the function result set, not the entire query result set.
For details about supported functions, see Analytic Functions in the SQL Reference Manual.
