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™.

Create an etx index

To create an etx index, you specify the etx access method in the USING clause of the CREATE INDEX statement. You specify the operator class right after specifying the indexed column.

You must create an etx index for each text column you plan to search. You cannot alter the characteristics of an etx index after you create it. Instead, you must drop the index and recreate it with the desired characteristics.
