I want to create index on Abstract Field ...Just like the capability of
Oracle InterMediaText in which Themes can be generated using any of the
field....
Example of oracle InteMedia Text is
SQL> create table DSpace
(id number Primary Key,
Abstract varchar2 (5000)
)
/
Table created.
SQL> create table mythemes
(Qry_id number Primary Key,
Theme varchar2 (1500)
Weightage number
)
/
Table created.
Inserting data into table
SQL> Insert into DSpace (id, Abstract
(01,
‘Go to your favourite web search engine, type in a frequently occurring word
on the internet like “database”, and wait for plethora of search result to
return.’
)
/
1 Row created.
SQL> commit;
Commit complete
Index Creation
SQL> Create index my_idx on DSpace (Abstract) indextype is ctxsys.context;
Index created
PL/SQL Procedure
SQL> Begin
Ctx_doc.theme(index_name => ‘my_idx’,
