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.
DataBlade® API Function ReferenceThese topics describe the DataBlade® API functions and the subset of HCL OneDB™ ESQL/C functions that the DataBlade® API supports.The HCL OneDB™ DataBlade® API Function Reference describes the DataBlade® API functions and the subset of HCL OneDB™ ESQL/C functions that the DataBlade® API supports.
Categories of DataBlade® API functionsThis section summarizes by categories the functions that the DataBlade® API provides. It divides functions that are valid within DataBlade® API modules into several functional categories and lists the functions within each category.
