Oracle Debugging Techniques

Debug Workflow

1. Reproduce with minimal dataset.
2. Trace critical variables using DBMS_OUTPUT.
3. Inspect failing SQL and exception points.
4. Validate fix with repeatable test script.

Common Focus Areas

• SELECT INTO no-data/multi-row errors.
• Constraint violations during DML.
• Slow queries due to poor plans/index usage.

Summary

Use deterministic test data and trace points to debug quickly.
