The driver supports polymorphic functions in SQL. To access those functions through the DDL, each function or procedure is assigned a generated implementation name to make it unique for reference in schema manipulation commands. If you prefer to provide your own reference name, instead of the generated one, you can specify it using the SPECIFIC statement. Using this statement assists in referencing the correct function in metadata or DDL statements when you have multiple similar functions. 
SPECIFIC <reference_name>

where:

reference_name
is a unique reference created by you to be used in schema manipulation commands.
