Extending HCL OneDB™Beyond standard relational database objects, HCL OneDB™ can be extended to handle specialized data types, access methods, routines, and other objects. HCL OneDB™ includes many built-in extensions that are fully integrated in the database server. HCL OneDB™ also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for HCL OneDB™.
Creating extensionsYou can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in HCL OneDB™ databases.
User-Defined Routines and Data Types Developer's GuideThe HCL OneDB™ User-Defined Routines and Data Types Developer's Guide describes how to define new data types and enable user-defined routines (UDRs) to extend HCL OneDB™.
Create user-defined aggregates
Drop an aggregate

Drop an aggregate

The DROP AGGREGATE statement removes the definition of an aggregate from the database. You must be the owner of the aggregate or the database administrator (DBA) to drop its definition from the database.

If you are the owner or the DBA, the following statement removes the aggregate SUMSQ from the database:

DROP AGGREGATE SUMSQ;

Dropping an aggregate has no effect on functions that are associated with the aggregate. Use the DROP FUNCTION statement to remove a function from the database.
