    first_name VARCHAR2(50),
    last_name VARCHAR2(50),
    hire_date DATE,
    salary NUMBER
);
Enter fullscreen mode Exit fullscreen mode

Insert Data

INSERT INTO employees (employee_id, first_name, last_name, hire_date, salary)
VALUES (1, 'John', 'Doe', TO_DATE('2020-01-01', 'YYYY-MM-DD'), 60000);

INSERT INTO employees (employee_id, first_name, last_name, hire_date, salary)
VALUES (2, 'Jane', 'Smith', TO_DATE('2021-02-15', 'YYYY-MM-DD'), 75000);
Enter fullscreen mode Exit fullscreen mode

Select Data

SELECT * FROM employees;
Enter fullscreen mode Exit fullscreen mode

Update Data

UPDATE employees
SET salary = 80000
WHERE employee_id = 1;
Enter fullscreen mode Exit fullscreen mode

Delete Data

DELETE FROM employees
WHERE employee_id = 2;
Enter fullscreen mode Exit fullscreen mode

Example: Simple PL/SQL Block Using Variables

DECLARE
    v_employee_id NUMBER := 1;
    v_first_name VARCHAR2(50);
    v_last_name VARCHAR2(50);
    v_salary NUMBER;
BEGIN
    SELECT first_name, last_name, salary
    INTO v_first_name, v_last_name, v_salary
    FROM employees
    WHERE employee_id = v_employee_id;

    DBMS_OUTPUT.PUT_LINE('Employee: ' || v_first_name || ' ' || v_last_name || ', Salary: ' || v_salary);
END;
/
Enter fullscreen mode Exit fullscreen mode

Example: Creating a Stored Procedure

CREATE OR REPLACE PROCEDURE raise_salary (
    p_employee_id IN NUMBER,
    p_amount IN NUMBER
) IS
BEGIN
    UPDATE employees
    SET salary = salary + p_amount
    WHERE employee_id = p_employee_id;

    COMMIT;
END;
/
Enter fullscreen mode Exit fullscreen mode

Example: Using SQL*Loader to Import Data
Control File (load.ctl):

LOAD DATA
INFILE 'employees.csv'
INTO TABLE employees
FIELDS TERMINATED BY ',' 
( employee_id, first_name, last_name, hire_date DATE 'YYYY-MM-DD', salary )
Enter fullscreen mode Exit fullscreen mode

Command to Run SQL*Loader:
