Chapter 2. Functions and Operators

Hyper provides a large number of functions and operators for the built-in data types.

If you are concerned about portability then note that most of the functions and operators described in this chapter, with the exception of the most trivial arithmetic and comparison operators and some explicitly marked functions, are not specified by the SQL standard. Some of this extended functionality is present in other SQL database management systems, in particular PostgreSQL, and in many cases this functionality is compatible and consistent between the various database systems. This chapter is also not exhaustive; additional functions appear in relevant sections of the manual.
