Hello SQL Dev team,
New version implies new bugs sadly. But this one is a regression :-(
DDL Code extracted from the database using DBMS_METADATA package is truncated.
SELECT DBMS_METADATA.get_ddl ('TABLESPACE', tablespace_name)
FROM dba_tablespaces
WHERE tablespace_name = 'FOODSUP';
-- 23.1 --

-- 22.2.1 --

Executing with Run Script yields the complete command.
