SAP Sybase SQL Anywhere 16.0 » SQL Anywhere Server - SQL Reference


SQL functions

Functions are used to return information from the database. They can be called anywhere an expression is allowed.

Unless otherwise specified in the documentation, NULL is returned for a function if any argument is NULL.

If an argument is optional, DEFAULT can be provided as an argument.

Functions use the same syntax conventions used by SQL statements.
