You can also use the $ORACLE_HOME/rdbms/admin/utldtree.sql utility to find out how the dependency tree looks like and which objects are dependent on e.g. DBMS_PIPE. One of those objects will be the sql statement
('public.unaccent', $1); $$ LANGUAGE sql IMMUTABLE COST 1; the indexes are exported as follow: CREATE INDEX t_document_title_unaccent_trgm_idx ON t_document USING gin (unaccent_immutable(title) gin_trgm_ops); In your queries you will need to use the same function in the search to ...

The challenge here is there could be any size gap between rows. It’s possible to solve this using recursive queries or themodelclause. But I prefer to useSQL pattern matching. This looks like: Copy code snippet Copied to Clipboard
For example, the two queries in Example 4-7 are equivalent. Example 4-7. Using the NOT operator SELECT * FROM employee WHERE employee_id <> 114; SELECT * FROM employee WHERE NOT employee_id = 114; NOT can be handy when writing complex queries because sometimes it's easier to think in...
