CREATE FUNCTION Statement¶

Confluent Cloud for Apache Flink® enables registering customer user defined functions (UDFs) by using the CREATE FUNCTION statement. When your UDFs are registered in a Flink database, you can use it in your SQL queries.

Syntax¶

CREATE FUNCTION <function-name>
  AS <class-name>
  USING JAR 'confluent-artifact://<plugin-id>/<version-id>';

Description¶

Register a user defined function (UDF) in the current database.

To remove a (UDF) from the current database, use the DROP FUNCTION statement.
