3. Can I write anonymous PL/SQL blocks using DECLARE, BEGIN, and END?

Yes. Anonymous blocks are one of the most useful ways to practice PL/SQL logic.

You can also test conditions:

And loops:

4. What is the main difference between SQL and PL/SQL?

SQL is mainly used to retrieve, insert, update, delete, and manage relational data. PL/SQL extends SQL with programming features such as variables, conditions, loops, cursors, procedures, functions, and exception handling.

A standard SQL query might look like this:

PL/SQL allows procedural logic around database operations:

Use SQL when you primarily need to work with data, and PL/SQL when you need procedural logic around Oracle database operations.
