Scalar User-defined Functions (UDFs)
Custom scalar functions can be created for use in queries to extend database functionality. Functions can be written in SQL, JavaScript and Python.
Use the following SQL statements:
CREATE FUNCTION to define a function
DROP FUNCTION to remove a function
UDFs must be enabled and configured as described in the System Administrator Guide.
Note:  Currently, only SQL UDFs support BYTE and VARBYTE arguments.
