Introduction

PL/SQL (Procedural Language/SQL) is Oracle’s extension to SQL, enabling developers to write more powerful queries and procedures for complex data management. While PL/SQL is powerful, writing accurate code can be time-consuming — especially for beginners.

With AI2SQL, you can generate PL/SQL queries from plain English in seconds. In this guide, we’ll walk through 10 real-world PL/SQL examples, from beginner-friendly queries to advanced use cases, showing how AI2SQL can simplify your workflow.

Beginner Examples

1. Select All Customers

Request: “Get all customers from the customers table.”

SELECT * FROM

2. Count Orders in the Last 30 Days

Request: “Count orders placed in the last 30 days.”

SELECT COUNT(*) 
FROM orders 
WHERE order_date >= SYSDATE - 30

3. Display Employee Names and Salaries

Request: “Show employee names and salaries from employees table.”

SELECT name, salary 
FROM

4. Find the Maximum Salary

Request: “Find the highest salary in employees.”

SELECT product_name 
FROM products 
WHERE category = 'Electronics'

Intermediate Examples

6. Join Customers and Orders

Request: “Get customer names and their orders.”

SELECT c.name, o.order_id, o.total 
FROM customers c 
JOIN orders o ON

7. Calculate Average Salary by Department

Request: “Show average salary by department.”

SELECT department_id, AVG(salary) AS avg_salary 
FROM employees 
GROUP BY

8. Insert a New Employee

Request: “Insert a new employee John Doe in Sales with salary 5000.”

INSERT INTO employees (name, department, salary) 
VALUES ('John Doe', 'Sales', 5000)

Advanced Examples

9. Create a PL/SQL Procedure for Bonus

Request: “Create a procedure to add 10% bonus to salaries in Sales.”

CREATE OR REPLACE PROCEDURE add_bonus IS
BEGIN
    UPDATE employees
    SET salary = salary * 1.10
    WHERE department = 'Sales';
END

10. Use a Cursor to Fetch Orders

Request: “Create a cursor to fetch all orders above $1000.”

DECLARE
    CURSOR high_value_orders IS
        SELECT order_id, total 
        FROM orders 
        WHERE total > 1000;
    order_record high_value_orders%ROWTYPE;
BEGIN
    OPEN high_value_orders;
    LOOP
        FETCH high_value_orders INTO order_record;
        EXIT WHEN high_value_orders%NOTFOUND;
        DBMS_OUTPUT.PUT_LINE('Order ID: ' || order_record.order_id || 
                             ' Total: ' || order_record.total);
    END LOOP;
    CLOSE high_value_orders;
END
