Scalar User-defined Functions (UDFs)
Custom scalar functions can be created for use in queries to extend database functionality. Use the CREATE FUNCTION statement to define a function and the DROP FUNCTION statement to remove it. Functions can be written in SQL.
Note:  SQL UDFs are a development release. Please work with Actian Support before using such UDFs in a production environment.
