1. PL/SQL

PL/SQL is Oracle’s procedural extension to SQL. Blocks, variables, loops, exceptions—tight integration with SQL right inside the database. It’s the backbone for encapsulating business logic close to the data, where it belongs.

Why It's Important

PL/SQL lets you build secure, performant, and portable database-centric applications. Put logic in the database. Reduce round trips. Improve integrity. It’s the core tool for serious Oracle work.

How to Improve PL/SQL Skills

Go deep on fundamentals and write code that’s clean, fast, and safe. Short punch list:

1. Nail the basics: Master SQL first, then PL/SQL control structures, scoping, and datatypes.

2. Bind variables everywhere: Better plans, safer code, happier cache.

3. Write efficient SQL: PL/SQL won’t save a bad query. Tune joins, predicates, and projections.

4. Use collections and records: Batch with BULK COLLECT and FORALL. Cut context switches.

5. Handle errors deliberately: Use structured EXCEPTION blocks. Log. Propagate with care. No silent failures.

6. Optimize hot paths: Avoid unnecessary conversions and loops. Profile, then refactor.

7. Package your code: Group related procedures and functions. Hide internals. Keep APIs crisp.

8. Test and debug: Unit test logic-heavy routines. Use step debugging and trace when needed.

9. Code reviews: Enforce standards. Naming, error handling, performance conventions—make them stick.

10. Keep learning: New features land steadily. Explore result cache, function inlining, and more.

Practice on real problems. Measure. Iterate. That’s how PL/SQL gets sharp.
