कोई आदेश नहीं है 'ALTER TABLE XXX DISABLE ALL CONSTRAINTS'
मैं इसका प्रस्ताव करता हूं;
BEGIN
FOR c IN (SELECT table_name, constraint_name FROM user_constraints WHERE constraint_type = 'R')
LOOP
EXECUTE IMMEDIATE ('alter table ' || c.table_name || ' disable constraint ' || c.constraint_name);
END LOOP;
FOR c IN (SELECT table_name FROM user_tables)
LOOP
EXECUTE IMMEDIATE ('truncate table ' || c.table_name);
END LOOP;
FOR c IN (SELECT table_name, constraint_name FROM user_constraints WHERE constraint_type = 'R')
LOOP
EXECUTE IMMEDIATE ('alter table ' || c.table_name || ' enable constraint ' || c.constraint_name);
END LOOP;
END;
